What is Cryptocurrency?
Cryptocurrency is a form of digital currency that is decentralized and uses cryptography to secure transactions. The first and most well-known cryptocurrency is Bitcoin, which was created in 2009. Unlike fiat currencies like the U.S. Dollar or Euro, cryptocurrencies are not controlled by any government or central authority.
The "crypto" part of the word refers to cryptography, which is the process of encrypting and decrypting information. Cryptocurrencies use cryptography to regulate the creation of new currency units and verify transactions.
How Does Cryptocurrency Work?
Cryptocurrencies run on distributed ledger technology called blockchain. When a transaction occurs, it is recorded on a public ledger that is updated across thousands of computers globally through a network of nodes. Nodes are users who maintain the network by hosting copies of the blockchain on their devices.
The nodes validate transactions through cryptography, ensuring that the sender has sufficient funds and has not already spent them. Valid transactions are combined into blocks, which form the blockchain.
Decentralization
A key feature of cryptocurrencies is their decentralized nature, meaning they are not issued or regulated by any central authority like a government or bank. The lack of central control makes cryptocurrencies immune to manipulation or interference from governments.
Anonymity
For most cryptocurrencies, transactions are pseudonymous rather than anonymous. Each transaction is linked to a crypto wallet address comprised of letters and numbers. While the crypto address does not reveal the identity of the owner, transactions can potentially be traced back to a person or entity.
Irreversibility
Unlike credit card or bank transactions, crypto transactions are irreversible once added to the blockchain. This prevents the possibility of chargebacks or cancellations, which protects merchants but means extra care must be taken by buyers.
Supply Limits
Many cryptocurrencies have a fixed or maximum supply that cannot be exceeded. For example, only 21 million Bitcoins can ever be created. These supply limits result in deflation and contribute to cryptocurrencies being seen as scarce digital assets. The limited supply helps cryptocurrencies hold and increase their value over time compared to assets with unlimited supply.
Types of Cryptocurrencies
There are thousands of cryptocurrencies in existence today. Besides Bitcoin, some other major cryptocurrencies include:
Ethereum (ETH)
Ethereum is the second largest cryptocurrency after Bitcoin in terms of market capitalization. Along with being a tradeable cryptocurrency, the Ethereum network supports decentralized apps and smart contracts.
Litecoin (LTC)
Litecoin is similar to Bitcoin but processes transactions faster and has lower transaction fees. There is a limit of 84 million Litecoins that can ever be created.
Cardano (ADA)
Cardano uses a Proof of Stake consensus mechanism that is less energy intensive than Bitcoin's Proof of Work method. It aims to allow decentralized apps and smart contracts like Ethereum.
XRP (Ripple)
XRP was created by Ripple Labs and is designed for fast, global financial transactions. It is used by banks and other financial institutions rather than individual investors.
Polkadot (DOT)
Polkadot aims to allow interoperability between different blockchains and decentralized networks. Its native DOT token provides network governance and operations.
Dogecoin (DOGE)
Dogecoin is a meme-based cryptocurrency that features the Shiba Inu dog from the "Doge" meme. It has a very high coin supply and is well suited for micropayments and tips.
How to Buy Cryptocurrency
There are a few ways you can buy and begin investing in cryptocurrency:
Cryptocurrency Exchanges
Cryptocurrency exchanges like Coinbase, Kraken and Binance allow you to buy and sell major cryptocurrencies like Bitcoin and Ethereum. You can create an account, deposit funds and then start trading coins. Exchanges also securely store your coins in hosted crypto wallets. Fees vary across exchanges.
Brokerages
Many brokerages like Robinhood, Webull and SoFi also now allow users to buy and sell popular cryptocurrencies. This option may be simpler for investors already using a brokerage account to buy other asset classes like stocks and ETFs. Trading fees at most brokerages are $0.
P2P Exchanges
Peer-to-peer (P2P) exchanges like LocalBitcoins and Paxful connect cryptocurrency buyers directly with sellers. Payments can be made via cash, bank transfer, PayPal or other methods. P2P exchanges are higher risk but allow more payment flexibility.
Cryptocurrency ATMs
There are thousands of Bitcoin ATMs or BTMs around the world that allow you to physically deposit cash to immediately purchase cryptocurrency without needing an account. However, BTMs charge high convenience fees.
Accepting Cryptocurrency Payments
If you operate a business, you can begin accepting direct cryptocurrency payments through payment processors like BitPay and CoinPayments. This allows you to receive settlements in digital currencies instead of cash or bank deposits.
How to Store Cryptocurrency
Once you've bought cryptocurrency, you'll need a secure place to store it outside of the exchange account. Here are some of the best options for safely storing crypto:
Digital Wallets
Software and mobile apps like Trust Wallet or Coinbase Wallet provide free digital wallets to safely store your private keys and crypto. Wallets also allow you to personally manage your crypto funds.
Hardware Wallets
Physical hardware wallets like Ledger and Trezor offer offline, cold storage for your private keys. Storing your keys offline offers greater security against hacking and theft. Though more costly than software wallets, hardware wallets provide top-tier security.
Paper Wallets
A paper wallet involves printing out your private and public keys in QR code form and storing this piece of paper somewhere very safe like a bank vault. As long as the paper remains intact, your coins are accessible.
Crypto Debit Cards
Debit cards linked to crypto wallets like Wirex and Crypto.com allow you to conveniently spend your cryptocurrency balance at stores or ATMs just like a regular debit card. The crypto is instantly converted to fiat currency by the provider.
Safe Storage
However, you store your cryptocurrency, some basic measures apply for keeping it secure like using passwords with special characters, enabling two-factor authentication and safely backing up your wallet. Also avoid publicly sharing your crypto wallet addresses and keys.
