Learning the friendly way

Both hard and soft forks are fundamental to blockchain development and cryptocurrency evolution. The hard fork is what offers the ability for different cryptocurrencies to split into two and allows them to compete with each other, offering new features or security upgrades that appeal to users looking to buy in a particular niche.

Both soft and hard forks happen whenever a community makes a change to the blockchain’s protocol or basic set of rules. This is different from an update: updates often lead to improvements in the software (for example, adding new features), whereas soft and hard forks can result in changes that may not be compatible with existing code.

Cryptocurrency forks are important because they can be used to change blockchain rules, instead of forcing users to upgrade their software. This allows new cryptocurrency development teams to fix bugs and issues without forcing everyone else onto new software versions. Soft and hard forks enable cryptocurrencies that have diverged from the original codebase to solve problems using a consistent protocol across two branches.

A hard fork creates a new blockchain that shares the same history as another blockchain. The best way to imagine it is like splitting an old road into two new roads, both of which have their own unique set of rules and paths. To understand the term and concept of blockchain forks more accurately, let's look at the difference between a hard fork and a soft fork.

Cryptocurrency forks: Hard Forks and Soft Forks

What Is A Hard Fork?

A hard fork is when a blockchain splits in two and a new cryptocurrency network is created. The hard fork happens when there’s a fundamental change to the blockchain, such as upgrading one of its core technical components (ie: blocksize). This requires everyone who uses that blockchain to upgrade their software or else they will no longer be able to participate on the network. Users can also opt to be a part of both blockchains that result from cryptocurrency forks.

When a hard fork occurs two unique blockchains are created that each have their own cryptocurrencies, and is usually a result of a community split over a decision or vision for the future. A hard fork is a common occurrence in the cryptocurrency industry, with many big cryptocurrencies being the product of a successful hard fork.

An Example of a Hard Fork: the Bitcoin Cash Fork

Bitcoin Cash is a prime example of a hard fork. In 2017, following a disagreement within the Bitcoin community about the future of the original cryptocurrency, a group of developers and miners got together to form a new and improved version known as Bitcoin Cash. The Bitcoin Cash hard fork was implemented and BCH was created, with several new additions to the original blockchain code.

The most significant change to the Bitcoin Cash network was the increase of the block size to 8MB, allowing for faster transaction speeds, more transactions able to get verified at once, and lower transaction fees. The network also increased the difficulty to ensure the security of the network would not be compromised. In March 2022, the block size limit was increased to 32MB.

There have been many Bitcoin forks over the years, with Bitcoin Cash and Litecoin being the two most well-known.

What Is A Soft Fork? 

Soft forks is backward-compatible and require upgrades only if you want to access new features. For example, soft forks that increase transaction speed don’t require everyone to upgrade their software in order to enjoy the new feature.

If you don’t upgrade your software, however, you will not be able to take part in any future transactions using the new feature (ie: faster transaction speeds). Soft forks are a great way for new changes to be implemented without creating an entirely new cryptocurrency.

An Example Of A Soft Fork: The SegWit Upgrade

In 2015, the Bitcoin blockchain underwent a soft fork known as the Segregated Witness (SegWit) Bitcoin protocol update.

Before the SegWit upgrade, Bitcoin's protocol was both more expensive and slower, with transactions costing about $30 each and taking around an hour to complete. The inventors of the SegWit change recognized that signature data accounts for 65% of a transactional block. As a result, SeGWit proposed moving the effective block size from 1MB to 4MB.

The motivation for this increase was to separate or delete the signer data from the transactional data on every block of the blockchain, allowing for greater transaction throughput per block.

With the soft fork, the old Bitcoin blockchain was able to accept both new 4MB and 1MB blocks at the same time. The soft fork enabled the existing nodes to also validate the new blocks via a clever engineering approach that formatted new rules without breaking existing ones.

What To Do When A Fork Is Announced

When it’s announced that a fork is coming, you should first wait for the dust to calm down before making any big decisions, such as buying or selling your tokens. Keep in mind that sometimes forks can be contentious and not everyone will agree on the path forward, meaning that there may be a lot of confusion and volatility in the coming days as people react.

 In Conclusion

A hard fork is when blockchain technology is split into two resulting in two unique blockchain networks with their own cryptocurrencies. A soft fork is when a blockchain simply upgrades or incorporates new features and allows users to decide whether they would like to continue using the old version, or upgrade their software protocol to make use of the new features.

Either way, cryptocurrency forks are a common occurrence in the blockchain space and have been the start of many different networks. The most iconic hard forks include the likes of Litecoin, a hard fork from the Bitcoin network, Ethereum Classic, a hard fork from the Ethereum network, and Bitcoin Cash, a hard fork of the Bitcoin network.

Both soft and hard forks allow innovation within the blockchain space to evolve, making space for new features, more efficient means of executing an action, and other chain improvements. Hard forks in particular have shed light on new innovations without creating a blockchain network from scratch.

You’ve probably heard whispers about the "whales" swimming in the crypto seas. But these aren’t your typical marine mammals – they’re the ultra-wealthy folks and organizations holding massive amounts of digital currency.

What Exactly is a Crypto Whale?

So, what makes someone a crypto whale? There’s no hard-and-fast rule, but it generally comes down to owning a huge chunk of a coin’s total supply. We’re talking over 10% of the available coins for a particular cryptocurrency. That’s an ocean-sized wallet!

Take Bitcoin, for example. In May 2022, just four wallets controlled over 3% of all Bitcoin in existence. The top 100 wallets? They collectively held over 15%. Now that’s some serious whale power!

Bitcoin isn’t the only one with its share of whales. Dogecoin, the beloved meme coin, had a pretty wild concentration too. In 2022, just 15 addresses held nearly 52% of its total supply. Even Vitalik Buterin, the mastermind behind Ethereum, is considered an Ether whale thanks to his massive stake in the coin he created.

How Whales Make Waves

With that kind of buying power, whales can really make waves in the crypto marketplace. If a whale decides to sell off a giant chunk of their holdings, it creates a tidal wave of downward pressure on prices due to the sheer volume and lack of liquidity. Other crypto enthusiasts are always on the lookout for signs of an impending "whale dump," closely monitoring exchange inflows to spot potential dangers.

Here’s the twist, though – whales keeping their coins locked away actually reduces trading liquidity in the market since there are fewer coins actively circulating. Their massive idle fortunes are like icebergs weighing down the crypto ocean.

Tracking Whale Movements

Not every whale transaction is a sell-off. These giants could simply be migrating to new wallets, switching exchanges, or making monster-sized purchases. But you can bet experienced crypto folks keep a keen eye on those huge whale wallets, carefully tracking any ripples they make to navigate the ever-shifting tides of the market.

Whale Alert is a popular service that tracks these large transactions and reports them, often on Twitter. Whenever a whale makes a big move, it’s usually publicized quickly, giving everyone a heads-up on potential market changes.

Below is an example from Twitter from Whale Alert:

The Human Side of Whales

Behind these massive holdings are real people and organizations. Some whales are early adopters who bought into Bitcoin or other cryptocurrencies when they were cheap. Others are companies that have invested heavily in the belief that cryptocurrencies will continue to grow in value. For instance, Ethereum’s founder, Vitalik Buterin, is the biggest Ethereum whale because he holds a significant amount of the cryptocurrency he created.

How whales affect crypto's price

Price volatility can be increased by whales, particularly when they move a significant amount of one cryptocurrency in one go. For example, when an owner tries to sell their BTC for fiat currency, the lack of liquidity and enormous transaction size create downward pressure on Bitcoin's price. When whales sell, other investors become extremely vigilant, looking for hints of whether the whale is "dumping" their crypto (and whether they should do the same). 

The exchange inflow mean, also known as the average amount of a certain cryptocurrency deposited into exchanges, is one of the most common indicators crypto investors look for. If the mean transaction volume rises above 2.0, it implies that whales are likely to start dumping if there are a large number of them using the exchange. This can be viewed by regular crypto traders as a time to act before losing any potential profit.

How whales effect liquidity

When it comes to learning about whales and liquidity, one must remember that while whales are generally considered neutral elements in the industry, when a large number of whales hold a particular cryptocurrency, instead of using it, this reduces the liquidity in the market due to there being fewer coins available. 

What crypto whales mean to investors

In terms of the relationship between whales and investors, one must remember that there are various situations in which a person may transfer their cryptocurrency holdings. It's worth mentioning that moving one's assets doesn't always indicate that you're selling them; they might be switching wallets or exchanges, or making a major purchase.

Occasionally, whales may sell portions of their holdings in discrete transactions over a longer period to avoid drawing attention to themselves or generating market anomalies that send the price up or down unpredictably. This is why investors keep an eye on known whale addresses to check for the number of transactions and value. This is not necessarily a task that newbie investors need to actively be involved with, however, understanding the terms and how whale accounts can affect the market is recommended.

Why Whales Matter

Whether you love them or hate them, whales are a formidable force in the crypto world, shaping its dynamics in profound ways. These giants, whether they’re creators, collectors, or traders, have a tremendous impact across the digital waters. When they make a move, it can trigger monumental swells that ripple through the entire market.

By understanding whale activity, anyone involved in cryptocurrency can better navigate these choppy waters. Staying informed about whale movements helps both newbies and seasoned traders make smarter decisions and stay afloat in this ever-changing space. Keep an eye on these behemoths; their actions can significantly influence your crypto journey.

While tracking whale activity can offer valuable insights into the cryptocurrency market, it's important to complement this knowledge with expert advice. Consulting with a financial advisor can help you navigate the complexities of investing and ensure your strategies align with your personal financial goals and risk tolerance.

As you navigate the waters of the cryptocurrency market you're likely to come across a term called "coin burning". In this article, we're exploring the process used to manage the token supply of projects, a means for companies to manually alter the supply (and thereby demand) of a token's circulating supply. While not adopted by every project, coin burning has proven over the years to be successful in increasing the price of a digital currency.

What Is A Coin Burn

Diving right in, a coin burn is the process of removing a certain number of tokens from circulation by sending them to an invalid address, a "black hole" of sorts. This process is written into the project's code and implemented at various increments as outlined in the whitepaper. While Bitcoin doesn't make use of coin burning, many projects on the Ethereum network, particularly ERC-20 tokens, have been known to implement it.

Through the use of a smart contract, also known as a burn function, the network would remove a specified number of tokens from circulation, decreasing the total supply and thereby (hopefully) increasing the demand. Coin burns have been known to lead to an increase in price, as the supply-demand ratio is altered.

An Example Of Coin Burning

A top 10 cryptocurrency project underwent a coin burn last year that is believed to be the biggest layer 1 token burn to date. 88.7 million LUNA, the native coin to the Terra project, were burned in November 2021 following a vote by the community. This was effectively worth $4.5 billion at the time. A few days following the coin burn the LUNA token hit a new record high. 

The burn aimed to remove value from Terra’s community pool, but in reality, it simply moved the value from the pool to the individual holders of the cryptocurrency.

Bitcoin Cash and Stellar are two other high profile cryptocurrencies that have made use of the coin burning initiative. Shiba Inu is another cryptocurrency to have undergone a coin burn, although this wasn't the initial intention of the project. The project's developers gifted half of the SHIB supply to Ethereum creator Vitalik Buterin, who went on to donate 10% and burn the remaining 90%.

How Does Coin Burning Work?

Should a project wish to implement a coin burn they will need to create a smart contract. Smart contracts are digital agreements that execute when certain criteria have been met. Say a project wants to implement a coin burn every 200,000 blocks, they will create the burn function to include this instruction.

When this milestone is achieved, the coins will automatically move from the designated wallet to a wallet address that does not have a private key. Without a private key, these coins can never be recovered. The coins will then be sent from the one wallet address to the other and effectively be removed from circulation. The transaction (burn) will be added to the network's blockchain records and be available to view through the blockchain explorer.

The Downside To Coin Burning

Before you get into a project that undergoes coin burning it is important to note that coin burning does not guarantee an increase in the coin's price. The increase in price will depend on the network, the market climate and the current sentiment. During the Shiba Inu coin burn, while the price rose considerably, it soon returned to a more stable and substantially lower level.

Coin burning can also be used by ill acting developers to deceive the community. Say a project has a total supply of 100 million tokens and allocates 10 million to the platform's developers. They could then burn 40 million tokens, increasing their hold to 60% of the circulating supply on the network.

As with all transactions conducted on the blockchain, all payments are irreversible meaning that once you burn coins they can never be recovered.

What Is Proof Of Burn?

Not to be confused with coin burning, Proof of Burn (PoB) is a consensus mechanism similar to Proof of Work and Proof of Stake. The model utilizes an element of coin burning in its mining practice and is known to use considerably less energy than its PoW counterpart.

The process requires miners to burn tokens in order to participate in the mining process. The more coins burned the more blocks they can create, meaning the more rewards (in the form of transaction fees) they can earn. Miners are still required to use mining hardware. The benefit of this is to provide a less energy-intensive blockchain network that can run optimally through a network of decentralized mining participants.

Cryptocurrency whitepapers are detailed documents that outline the project's intentions, products, and infrastructure. While there isn't a rule on what needs to be included, most projects aim to share as much information about how the project aims to succeed in the hopes of building investors' trust, and interest.

Some of the topics typically covered include a summary of the project's team, goals, products, features, and tokenomics. When researching a blockchain or cryptocurrency project, whitepapers are a very good place to start.

What is a whitepaper?

A typical cryptocurrency whitepaper is usually a report or guide that teaches its readers about a certain topic or problem. As an example, developers might make a whitepaper covering their software to inform users about what they are constructing and why.

In the crypto space, a whitepaper is released by a project and assists in outlining the technical guidelines and core features of the project. While many whitepapers focus on specific coins or tokens, they can also be concentrated around various types of projects, like decentralized finance (DeFi) platforms, for example.

Cryptocurrency whitepapers will typically consist of statistics and diagrams outlining the project's core date, as well as the governing structure of the project, the team involved in creating and leading it, and their roadmap (current and future development plans).

What value do crypto project whitepapers serve?

Despite not being worth a monetary value, whitepapers play an important role in the crypto space. While there are no official criteria for creating them, whitepapers are integral to investors, researchers, developers, and industry insiders.

A great place to start for anyone interested in a project is to read through the whitepaper. If you're considering tapping into a project, it's best to meticulously read through it again. Whitepapers often provide insights into the project's potential red flags and a means to monitor whether they are sticking to their forecasted timeline.

A number of blockchain projects that have crashed displayed subtle warning signs in their whitepaper, like promising a deliverable without providing any evidence on how it will be executed.

How does one make a cryptocurrency whitepaper?

There are no official rules or outlines that projects need to follow when creating a crypto whitepaper, each blockchain project may determine what is best for that individual situation. As mentioned earlier, these are often the first official documents outlining the project to potential investors, so thorough and informative content depicting the project's structure, goals, and roadmap is best included.

Whitepapers should always be neutral, and avoid persuasive language or making too many promises. This is essentially a "business plan" in the crypto sense released to investors or the public prior to launching.

What info is included whitepaper?

Objectives

Whitepapers are created by founders to provide a comprehensive overview of both the project and the goal. For instance, Bitcoin's whitepaper describes the project's core objective as "A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution."

While Ethereum's whitepaper describes its intention as "The intent of Ethereum is to create an alternative protocol for building decentralized applications."

In a good cryptocurrency whitepaper, the project will outline what specific problem it aims to solve, and how it will improve various aspects of people's lives. Be cautious of projects that promise the world but have little in the way of evidence to back these claims. In the ICO boom of 2017, thousands of projects overpromised and underdelivered (if they delivered at all).

Blockchain specifications

Whitepapers will typically include how the cryptocurrency will work and function in the greater crypto ecosystem. This might outline technical aspects like the consensus mechanism the blockchain will utilize and how the decentralized aspect of the network will function.

Tokenomics

Another core piece of information that should be included in a project's whitepaper is the tokenomics. This will include information on the token, how it will be allocated, whether will it participate in token burns, or any incentive mechanisms.

Roadmaps

Roadmaps (a project timeline)are not just useful to see how a project aims to deliver on its objectives, but also provide insights into whether the project can keep up with its promises. While missing a deadline isn't a deal breaker in the crypto space, being open and communicating why is important.

Readability

A well-articulated whitepaper will typically be written in a manner that anyone can understand them. However, its important for the new blockchain project to also include certain technical specifications to provide evidence of the project's competence. Anyone can write a whitepaper, it takes technical know-how to create a blockchain platform.

Tips for reading a cryptocurrency whitepaper

• first and foremost, ALWAYS read a project's whitepaper before putting any money.
• read whitepapers with a pinch of salt, they must be neutral and not over-promise.
• Look into the team members and their experience in the crypto and blockchain realm.
• a great idea doesn't necessarily mean it will be used or adopted.
• look for technical explanations that showcase the project's understanding.

Examples of crypto projects’ whitepapers

The Bitcoin whitepaper (2008)

The instigator of the entire cryptocurrency industry, Satoshi Nakamoto, an anonymous individual or group, published the Bitcoin whitepaper in 2008. The paper is called "Bitcoin: A Peer-to-Peer Electronic Cash System."

The whitepaper explains how Bitcoin can be used as a more efficient and decentralized form of money, outside the traditional banking model. It gives technical explanations of how the peer-to-peer Bitcoin network allows users to send digital currency without intermediaries. The whitepaper also outlines how the Bitcoin network is resistant to censorship and double-spending attacks.

The project launched two months later in January 2009.

The Ethereum whitepaper (2014)

While Bitcoin launched the crypto industry, Ethereum played a pivotal role in the development of the blockchain space. The Ethereum whitepaper was published in 2014 by a young developer named Vitalik Buterin and titled "Ethereum whitepaper: A Next Generation Smart Contract & Decentralized Application Platform."

In the Ethereum whitepaper, Vitalik outlines how the platform's intentions differ from Bitcoin's. The whitepaper outlined how the platform would allow developers to create and launch decentralized applications (now commonly known as dapps) and included technological solutions that backed these goals, such as the Ethereum Virtual Machine and smart contracts.

In conclusion

Crypto whitepapers are not legally regulated, meaning that anyone can write one. Although a cryptocurrency whitepaper should provide readers with an understanding of what the project plans to do and how, it's crucial, if you're interested in a particular project, to consider red flags and risks when reading through the document.

You might have come across the term crypto rug pull in the news over the years, but what does it mean? Different to a pump and dump scheme, we explore the rug pull crypto meaning to help you gain a greater understanding of the industry.

What is a Rug Pull Crypto?

A rug pull is a malicious cryptocurrency industry technique where developers abandon a crypto project and flee with investors' funds.

In the decentralized finance (DeFi) ecosystem, particularly on decentralized exchanges (DEXs), bad actors create a token and list it on a DEX, then link it to a major digital currency like Ethereum.

Developers will often also create hype around the token on Telegram, Twitter, and other social media platforms by abruptly pumping loads of money into their liquidity pool in an attempt to reassure investors. Once a large number of unsuspicious investors swap their ETH for the offered token, the creators drain everything from the liquidity pool, bringing the coin's price to zero.

This is typically seen in a new project, and not in established projects such as Bitcoin, Ethereum, etc.

Rugs Pools and DEXs

Rug pulls thrive on decentralized exchange platforms like DEXs since they allow users to list tokens without undergoing an audit, unlike centralized cryptocurrency exchanges. Furthermore, creating ERC-20 tokens on open-source blockchain technologies such as Ethereum is simple and free. These two features create the ideal climate for a rug pull, and are being used against the unsuspecting public.

What To Look Out For

While this is unlikely to happen to established cryptocurrency projects, there are many crypto projects out there, especially new ones, that might signal a red flag.

It's important to note that the prices of tokens in a pool are determined by the current balances of each. To prevent being caught off guard, ensure there is liquidity in a pool. However, this is only the beginning; you must also look for any lock-in requirements on the pooling system. Most reputable firms lock pooled liquidity for a certain length of time.

A coin that has risen in price within hours is another common feature of a rug pull. A rug pull coin, for example, might jump from 0 to 50X in just 24 hours. This scheme is intended to generate FOMO among investors and encourage them to add even more money into the project.

An "unruggable" project is one that doesn't have a significant number of tokens held by the development team. A project may be classed as "unruggable" if it does not include the signature big number of team-held tokens that could be stolen through a rug pull or exit scam.

An unruggable project is one in which the team gives up any ownership of tokens, such as those they would have received during a presale.

Are Crypto Rug Pulls Illegal?

While crypto rug pulls should be illegal, unfortunately, due to the youth of the crypto industry the laws surrounding rug pulls are not the legal system. Unfortunately, many criminals have and continue to get away with rug pulls and related crimes.

Biggest Rug Pulls

One of the biggest rug pulls to take place in the crypto industry is the Squid game crypto rug pull, which took place in late 2021.

The token, which was named after the popular Netflix series Squid Game was created by an unknown group, and grew dramatically in value with each coin rising from next-to-nothing to an astounding $2,861.

At the peak of its performance, the website was taken down and the promoters were unable to be reached. The liquidity suddenly vanished, sending the value of the token plummeting to near zero while the developers took home more than $3.3 million. Over 43,000 investors had the rug pulled out from under their feet as they suddenly become holders of a worthless token.

It was subsequently discovered that the project's creators had included an anti-dumping mechanism preventing individuals from selling their tokens, indicating that it was designed to be a rug pull from the beginning. By using the name of a well-known TV program and gaining a lot of media exposure, the creators were able to boost public awareness and lend the fraudulent coin a sense of legitimacy.

In Conclusion

While not terribly common, rug pulls happen from time to time and it's in investors' best interests to know about them. Consider these tips mentioned above when navigating the crypto space, and be sure to fully vet a project's quality before parting ways with any money. Choosing established cryptocurrency projects is always advisable, particularly over a new project that has garnered a lot of hype. Unfortunately, crypto rug pulls are here to stay, but that doesn't mean that you need to be involved.

When learning about paper wallets it's likely that you came across this option nestled safely in the “cold wallet” section in the different types of cryptocurrency wallets. While the popularity of paper wallets has somewhat declined, there are still a strong number of crypto enthusiasts that still appreciate the completely offline storage option. Let's explore what is a paper wallet and whether it's suited to your crypto needs.

What is a paper wallet?

For those needing a recap, a paper wallet is a piece of paper that holds both one’s public and private keys in both alphanumeric form and QR codes. Known as a non-custodial cold storage wallet, paper wallets allow the holders to manage their own private keys and remain entirely offline. A private key is a unique code that grants a user ownership of their wallet and digital funds, akin to a pin code for a bank account.

Creating paper wallets is incredibly simple, and can be completed in a matter of seconds. As a paper wallet "functions" offline, this makes them free from hackers, unlike a software wallet which is operated online. However, the paper wallet still carries its own set of risks in that the piece of paper cannot get damaged or lost.  Many Bitcoin paper wallets have been lost due to the paper fading or the information becoming illegible.

The objective of keeping a paper wallet is to keep the private key safe whether its for a Bitcoin paper wallet or one designed to hold any other cryptocurrency. Each crypto wallet will be designed to store one specific cryptocurrency.

The term Bitcoin wallet is a generic term for any type of crypto wallet, whether a paper wallet, a software wallet or any type of online wallet or hot wallet. The only distinguishing factor is that the digital wallet only holds Bitcoin.

Precautions for using paper wallets

While storing the paper wallet securely in a safe location makes the top of the list here, other precautions to take are listed below:

Quality printer

Always use a good quality printer. Ensure that your paper wallet is printed with a high-quality inkjet printed to ensure that the characters on the paper don’t fade or bleed over time. Should this happen you could lose access to your funds. 

Don’t share private keys

Never share your private keys with anyone. Paper wallets are designed to show the public key QR code on one side and the private key on the other. When sharing your public key with someone be sure not to accidentally share the private key as then they could gain access to your funds. 

Be sure to set up a change address

If you don't set up a change address before sending funds from a paper wallet, the leftover funds will go to waste. A change address is a separate wallet address that picks up the change from a transaction. 

If you have, for example, 100 BTC in your Bitcoin paper wallet and only spend 0.50 BTC, the remaining  99.5 BTC will either be sent to the change address or lost from your own paper wallet entirely. 

Paper wallets are not designed to be used for sending funds, but instead for receiving and storing funds for the long term. Hot wallets (as opposed to paper wallets) are better suited to users looking to frequently send and receive funds. There are plenty of crypto wallets on the market, ensure that you find the most convenient one for you.

Alternatively, funds can be stored in a yield-generating account where your funds can earn interest. Tap offers a wallet of this nature conveniently located on the app, which allows users to hold several crypto and fiat currencies and earn rewards based on each currency. The longer the funds remain there, the higher the yield.

While paper wallets remain offline, there are still risks associated with them. Be sure to adhere to the above precautions in order to keep your funds safe. 

Are paper wallets still relevant?

In the early days of crypto trading, paper wallets were strongly advised due to the offline safety of storing private keys. They began to be popular around the end of 2010 but unfortunately have been on a decline in more recent years as innovation in the industry has picked up momentum. A paper wallet is resistant to online attacks as long as it's made correctly; you can't hack a piece of paper.

In the past, people could create and print paper wallets for their crypto right from their exchange accounts. But now experts believe that hardware wallets are a more secure option, so most major exchanges don't offer this service anymore.

While some die-hard crypto traders still believe in the solid security of paper wallets, there are plenty of more innovative options available on the market today.
