You may be familiar with the most popular versions, Bitcoin and Ethereum, but there are more than 5, different cryptocurrencies in circulation. A cryptocurrency is a medium of exchange that is digital, encrypted and decentralized. Unlike the U. Dollar or the Euro, there is no central authority that manages and maintains the value of a cryptocurrency.
You can use crypto to buy regular goods and services, although most people invest in cryptocurrencies as they would in other assets, like stocks or precious metals. While cryptocurrency is a novel and exciting asset class, purchasing it can be risky as you must take on a fair amount of research to fully understand how each system works.
We've combed through the leading exchange offerings, and reams of data, to determine the best crypto exchanges. That cryptographic proof comes in the form of transactions that are verified and recorded on a blockchain. A blockchain is an open, distributed ledger that records transactions in code.
With a blockchain, everyone who uses a cryptocurrency has their own copy of this book to create a unified transaction record.
Software logs each new transaction as it happens, and every copy of the blockchain is updated simultaneously with the new information, keeping all records identical and accurate. To prevent fraud, each transaction is checked using one of two main validation techniques: proof of work or proof of stake. Cryptocurrencies typically use either proof of work or proof of stake to verify transactions.
The first computer to do so successfully is rewarded with a small amount of cryptocurrency for its efforts. This race to solve blockchain puzzles can require an intense amount of computer power and electricity. In practice, that means the miners might barely break even with the crypto they receive for validating transactions, after considering the costs of power and computing resources.
To reduce the amount of power necessary to check transactions, some cryptocurrencies use a proof of stake verification method.
To discourage fraud, if you are chosen and verify invalid transactions, you forfeit a part of what you staked. Both proof of stake and proof of work rely on consensus mechanisms to verify transactions. This means while each uses individual users to verify transactions, each verified transaction must be checked and approved by the majority of ledger holders.
The amount of resources necessary to do this makes fraud unlikely. Mining is how new units of cryptocurrency are released into the world, generally in exchange for validating transactions.
There are too many people who have optimized their equipment and technology to outcompete. And remember: Proof of work cryptocurrencies require huge amounts of energy to mine. It does, however, require that you already own a cryptocurrency to participate. If you have no crypto, you have nothing to stake. A handful of online retailers like Overstock. Until crypto is more widely accepted, you can work around current limitations by exchanging cryptocurrency for gift cards.
At eGifter, for instance, you can use Bitcoin to buy gift cards for Dunkin Donuts, Target, Apple and select other retailers and restaurants.
You may also be able to load cryptocurrency to a debit card to make purchases. In the U. You may also use crypto as an alternative investment option outside of stocks and bonds. To transfer money from your wallet, you can scan the QR code of your recipient or enter their wallet address manually. Some services make this easier by allowing you to enter a phone number or select a contact from your phone. Keep in mind that transactions are not instantaneous as they must be validated using proof of work or proof of stake.
Depending on the cryptocurrency, this may take between 10 minutes and two hours. This lag time, though, is part of what makes crypto transactions secure. Cryptocurrency can be purchased on peer-to-peer networks and cryptocurrency exchanges , such as Coinbase and Bitfinex. Keep an eye out for fees, though, as some of these exchanges charge what can be prohibitively high costs on small crypto purchases. Coinbase , for instance, charges a fee of 0. Some brokerage platforms—like Robinhood , Webull and eToro —let you invest in crypto.
They offer the ability to trade some of the most popular cryptocurrencies, including Bitcoin, Ethereum and Dogecoin, but they may also have limitations, including the inability to move crypto purchases off their platforms. Rather than buying only security, its better to spread your purchases out over many different options. If you want exposure to the crypto market, you might invest in individual stocks of crypto companies.
Experts hold mixed opinions about investing in cryptocurrency. By April , the price of BTC had more than doubled from where it started the year, but all those gains had been lost by July. As you can see, cryptocurrencies can be very volatile. That said, for clients who are specifically interested in cryptocurrency, CFP Ian Harvey helps them put some money into it.

Bitcoin mining is the process by which new bitcoins are entered into circulation. It is also the way the network confirms new transactions and is a critical component of the blockchain ledger's maintenance and development.
