Since its creation in 2009, Bitcoin (BTC +1.17%) has become a revolutionary digital currency. Because it enables peer-to-peer payments without a third party (like a bank), it has set off a tidal wave of other cryptocurrencies and digital assets making use of blockchain technology.
Blockchain is a digital public ledger where information on each transaction receives a unique "hash" (or identity) and is added to the end of the ledger. Bitcoin's success has put blockchain on the map and put its potential to decentralize and improve the digital economy on a path to disrupting the status quo.
Crypto coins vs. tokens
When discussing cryptos, you may hear the terms "coin" and "token" frequently used. Although they may sound like interchangeable terms, there is a difference, and it's important to keep them straight.
A digital coin is created on its own blockchain and acts in much the same way as traditional money. It can be used to store value and as a means of exchange between two parties doing business with each other. Examples of coins include Bitcoin and Litecoin (LTC +2.33%).
Tokens, on the other hand, have far more uses than just digital money. Tokens are created on top of an existing blockchain and can be used as part of a software application (like to grant access to an app, verify identity, or track products moving through a supply chain). They can represent digital art, including non-fungible tokens (NFTs) that certify something as unique. There has even been experimentation using NFTs with physical assets, such as real-life art and real estate.
Ether is an example of a token, which is used to make transactions on the Ethereum (ETH +2.08%) network.

There really isn't one "best" cryptocurrency since each has different features built in based on what the developer designed it for. Here's an overview of some of the most popular digital coins and how each is being used.
1. Bitcoin
Bitcoin is regarded as the first decentralized cryptocurrency using blockchain technology to facilitate payments and digital transactions. Instead of using a central bank to control the money supply in an economy (like the Federal Reserve in tandem with the U.S. Department of the Treasury) or third parties to verify transactions (such as your local bank, credit card issuer, and the merchant's bank), Bitcoin's blockchain acts as a public ledger of all transactions in the history of Bitcoin.
The ledger allows a party to prove they own the Bitcoin they're trying to use and can help prevent fraud and other unapproved tampering with the currency. A decentralized currency can also make peer-to-peer money transfers (like those between parties in two different countries) faster and less expensive than traditional currency exchanges involving a third-party institution.
2. Ether (Ethereum)
Ether is the token used to facilitate transactions on the Ethereum network. Ethereum is a platform that uses blockchain technology to enable the creation of smart contracts and other decentralized applications, meaning the software doesn't have to be distributed on app exchanges like Apple's (AAPL +2.34%) App Store or Alphabet's (GOOGL +3.62%)(GOOG +3.60%) Google Play Store, where they might have to give a 30% cut of any revenue to the tech giants. Ethereum is both a cryptocurrency (the actual coins are measured in units called Ether) and a software development sandbox.
3. Tether
Tether is a stablecoin, or a currency tied to a fiat currency -- in this case, the U.S. dollar. The idea behind Tether is to combine the benefits of a cryptocurrency (such as no need for financial intermediaries) with the stability of a currency issued by a sovereign government (vs. the wild price fluctuations inherent with many cryptos).
Are there different types of cryptocurrency trading?
Investing in cryptocurrencies is a little different than investing in shares of a company. Stock represents ownership of a business and a claim to profits the company generates. Purchasing coins of a cryptocurrency, though, is a speculative bet on the price movement of that digital currency -- which can be highly volatile and is subject to the law of supply and demand since digital currency by itself is not a dynamic asset. Cryptocurrencies can be exchanged for other digital currencies or for fiat currencies like the U.S. dollar using a digital wallet on a trading app.
But there are other ways to make money besides trading. Certain cryptocurrencies can be "staked" to earn rewards. Once an investor has purchased a crypto, it can be held in their account and used to verify transactions occurring on the blockchain network. This method of powering a blockchain network is known as "proof of stake," and the owner of the crypto can earn a type of dividend by staking their holdings, which are usually paid in additional coins or tokens.
In addition to trading digital currencies, derivatives contracts are also available on Bitcoin and Ethereum from leading derivatives exchange CME Group (CME +0.57%). Derivatives such as futures and options are primarily used as a hedge against price fluctuations in the underlying asset.
Where to buy all types of cryptocurrency
With so many cryptocurrencies out there right now, there is no single place that grants access to all of them. However, Coinbase Global (COIN +2.11%) is one of the largest trading platforms and currently supports more than 100 cryptocurrencies (including most of the top 10 largest cryptos by market cap). Binance is another top trading platform and is where Binance Coin and tokens can be traded.
If you're looking to buy company stock and cryptocurrency from a single place, here are the apps worth checking out:
These trading apps don't support all account types like full-service stock brokers do, but they have lots of functionality that combines basic crypto and stock trading with digital banking capabilities.
This is just the tip of the cryptocurrency iceberg. There are thousands of digital currencies utilizing blockchain technology that are being used for an incredibly diverse list of applications within the digital economy. Bitcoin is far and away the most popular crypto because it has picked up momentum among a young generation of consumers, but developers are always innovating new blockchain tech and uses for it.
The developments give other platforms, such as Ethereum, a lot of value since they are used to build new software. For investors trying to peer into the future, that could hold a lot of appeal since decentralized blockchain could remove third parties from business transactions and make payments around the world more efficient.
