What is cryptocurrency?

Cryptocurrency is a type of digital currency that generally exists only electronically. You usually use your phone, computer, or a cryptocurrency ATM to buy cryptocurrency. Bitcoin and Ether are well-known cryptocurrencies, but there are many different cryptocurrencies, and new ones keep being created.

How do people use cryptocurrency?

People use cryptocurrency for many reasons — quick payments, to avoid transaction fees that traditional banks charge, or because it offers some anonymity. Others hold cryptocurrency as an investment, hoping the value goes up.

How do you get cryptocurrency?

You can buy cryptocurrency through an exchange, an app, a website, or a cryptocurrency ATM. Some people earn cryptocurrency through a complex process called “mining,” which requires advanced computer equipment to solve highly complicated math puzzles.

Where and how do you store cryptocurrency?

Cryptocurrency is stored in a digital wallet, which can be online, on your computer, or on an external hard drive. A digital wallet has a wallet address, which is usually a long string of numbers and letters. If something happens to your wallet or your cryptocurrency funds — like your online exchange platform goes out of business, you send cryptocurrency to the wrong person, you lose the password to your digital wallet, or your digital wallet is stolen or compromised — you’re likely to find that no one can step in to help you recover your funds.

How is cryptocurrency different from U.S. Dollars?

Because cryptocurrency exists only online, there are important differences between cryptocurrency and traditional currency, like U.S. dollars.

• Cryptocurrency accounts are not backed by a government. Cryptocurrency held in accounts is not insured by a government like U.S. dollars deposited into an FDIC insured bank account. If something happens to your account or cryptocurrency funds — for example, the company that provides storage for your wallet goes out of business or is hacked — the government has no obligation to step in and help get your money back.
• Cryptocurrency values change constantly. The value of a cryptocurrency can change rapidly, even changing by the hour. And the amount of the change can be significant. It depends on many factors, including supply and demand. Cryptocurrencies tend to be more volatile than more traditional investments, such as stocks and bonds. An investment that’s worth thousands of dollars today might be worth only hundreds tomorrow. And, if the value goes down, there’s no guarantee it will go up again.

Paying With Cryptocurrency?

There are many ways that paying with cryptocurrency is different from paying with a credit card or other traditional payment methods.

How Does It Work?

1. Digital Coins: Just like you have coins in your piggy bank, cryptocurrency has digital coins. These coins are not made of metal; they are made of computer code.
2. Blockchain: Think of a big notebook where every time someone uses cryptocurrency, it gets written down. This notebook is called a blockchain. It keeps track of who has what coins, so everyone knows who owns what.
3. Wallets: To keep your digital coins safe, you need a special place called a wallet. This wallet is like a treasure chest on your computer or phone where you store your cryptocurrency.

Why Do People Use Cryptocurrency?

1. Buying Things: Some people use cryptocurrency to buy things online, like video games or clothes. It’s like using your allowance to buy snacks, but on the internet!
2. Trading: Just like trading cards with your friends, people can trade cryptocurrencies with each other. They hope to get more valuable coins in return.
3. Saving: Some people save their cryptocurrency, hoping it will be worth more in the future, just like saving your allowance to buy something bigger later.

How to Get Started

1. Learn: Before you start using cryptocurrency, it’s important to learn more about it. Ask questions and read books or watch videos.
2. Get a Wallet: If you want to use cryptocurrency, you’ll need a wallet. There are many types of wallets, so choose one that is easy to use.
3. Buy Some Coins: You can buy cryptocurrency using regular money. It’s like exchanging your allowance for digital coins!
4. Be Careful: Just like you wouldn’t share your secret hideout with strangers, be careful with your cryptocurrency. Keep your wallet safe and don’t share your secret codes with anyone.

Finding New Cryptocurrencies

1. Cryptocurrency Exchanges: These are like online stores where you can buy and sell cryptocurrencies. Some exchanges have sections for new coins. Look for exchanges like Binance, Coinbase, or Kraken, which often list new cryptocurrencies.
2. Crypto News Websites: Websites like CoinDesk, CoinTelegraph, and CryptoSlate share news about new cryptocurrencies. They often write articles about upcoming projects and new coins that are launching.
3. Social Media and Forums: Platforms like Twitter, Reddit, and Telegram have communities where people talk about cryptocurrencies. You can follow hashtags like #Crypto or join groups to hear about new coins from other enthusiasts.
4. Coin Market Cap Websites
5. Coin Market Cap Websites: Websites like CoinMarketCap and CoinGecko list many cryptocurrencies, including new ones. You can filter the list to see the newest coins and check their prices and market information.
6. Initial Coin Offerings (ICOs): Sometimes, new cryptocurrencies are offered through ICOs, which are like fundraising events. People can buy coins before they are officially launched. Be careful and do your research, as not all ICOs are safe.
7. Crypto Launchpads: These are platforms that help new cryptocurrencies launch. They often have a list of upcoming projects and allow you to invest early. Examples include Binance Launchpad and Polkastarter.

How to Research New Coins

1. Whitepapers: A whitepaper is a document that explains what a cryptocurrency is about, how it works, and what problems it aims to solve. Reading the whitepaper can help you understand if the coin is worth your attention.
2. Team and Community: Check who is behind the cryptocurrency. A strong team with experience and a supportive community can be good signs. Look for active discussions on social media or forums.
3. Use Cases: Think about what the cryptocurrency is trying to achieve. Does it solve a real problem? Is it useful? Coins with clear use cases are often more promising.
4. Market Trends: Keep an eye on market trends. Sometimes, certain types of coins become popular due to new technology or changes in the world. Understanding these trends can help you find new opportunities.
5. Risk Assessment: New cryptocurrencies can be risky. Some may not succeed, so it’s important to only invest what you can afford to lose. Diversifying your investments (not putting all your money into one coin) can also help manage risk.

Fun Facts

• Bitcoin: The first and most famous cryptocurrency is called Bitcoin. It’s like the superhero of digital money!
• Mining: Some people help keep the blockchain safe by solving puzzles on their computers. This is called mining, and they earn coins for their work.

Remember

Finding new cryptocurrencies can be exciting, but it’s important to do your homework. Just like trying a new flavor of ice cream, you want to make sure you’ll enjoy it! Always research and be cautious, and have fun exploring the world of cryptocurrency!
