Cryptocurrency Exchanges Explained
Cryptocurrency exchanges are online platforms where you can exchange one cryptocurrency for another cryptocurrency (or for fiat currency). In other words, depending on the exchange, it is either like a stock exchange or a currency exchange (at the airport or bank)
There are general there are the following types of exchanges:
NOTE: The terms used below are somewhat semantical. The important thing to note is the different styles of exchange, not the exact words used to describe them.
- “Traditional” Cryptocurrency Exchanges: These are the exchanges that are like the traditional stock exchanges where buyers and sellers trade based on the current market price of cryptocurrencies (with the exchange playing the middle-man). These type of trading platforms generally charge a fee for each transaction. Some of these types of exchanges deal only in cryptocurrency, others allow users to trade fiat currencies like the U.S. dollar for cryptocurrencies like Bitcoin. Coinbase’s GDAX (AKA Coinbase Pro) is an example of this type of exchange, as is Kraken . In general centralized exchanges will require a lot of info, but often allow fiat trading, and DEX exchanges won’t allow fiat trading, but require less information.
- Cryptocurrency Brokers: These are website-based exchanges that are like the currency exchange at an airport. They allow customers to buy and sell cryptocurrencies at a price set by the broker (generally at the market price plus a small premium). Here the exchange is between the buyer or seller and the broker, not between a buyer and seller. Coinbase is an example of this type of exchange. Shapeshift provides a similar service as well (it lets you swap on type of token for another). This is the simplest solution for new users. You’ll generally pay slightly higher prices than you do on the exchanges due to the ease of use and the work the broker puts in.
- Direct Trading Platforms: These platforms offer direct peer-to-peer trading between buyers and sellers. Direct trading platforms of this type don’t use a fixed market price. Sellers set their own exchange rate and buyers either find sellers via the platform and preform an Over the Counter (OTC) Exchange, or they denote the rates they are willing to buy for and the platform matches buyers and sellers. Many Decentralized Exchanges are of this type (although some are closer to being like traditional exchanges, which is why they are listed in the first category). This type of exchange can be the only solution in some regions. In regions where trading is limited to direct exchange, but where trading isn’t smart contract based (like it is with DEX exchanges), make sure to do some extra research and ensure you are using a trusted platform and dealing with highly rated users. Also, make sure to check market prices on Coinmarketcap, as you aren’t buying / selling at a fixed market price! For an example of a decentralized peer-to-peer direct trading platform, see AirSwap.io (here the DEX facilitates direct swaps between users via smart contracts, and thus may require no information). For an example of a centralized peer-to-peer exchange that facilitates the exchange of fiat and crypto.
- Cryptocurrency Funds: Funds are pools of professionally managed cryptocurrency assets which allows public buy and hold cryptocurrency via the fund. One such fund is GBTC Using a fund you can invest in cryptocurrency without having to purchase or store it directly. As a trade-off, you can’t use crypto in a fund as money, these are strictly for investment.
