Crypto Spread Eats into Trades: The Hidden Cost You Need to Know
The crypto spread is a hidden cost that can eat into your trades without you even realizing it. It's the difference between the bid price, which is the highest price a buyer is willing to pay for a coin, and the ask price, which is the lowest price a seller is willing to accept.
When you buy a cryptocurrency, you pay the ask price, which is higher than the bid price. Conversely, when you sell, you receive the bid price, which is lower than the ask price. The gap between these two prices is the spread, and it represents an immediate cost that you incur with each trade.
Exchanges make money from the spread in two primary ways: explicit trading fees and spread markups. On platforms with full order books, such as Binance, Kraken, and Coinbase Pro, the spread exists naturally and is set by the activity of buyers and sellers on the market. The exchange takes a small commission on each trade.
However, on simpler platforms or those that claim zero fees, the spread can be wider than the organic market spread because it's artificially inflated by the platform to compensate for lost revenue. This means that if you use an instant buy/sell service or a no-fee exchange, you may end up paying a higher effective spread without even realizing it.
To spot the spread before you trade, check the quoted price against an independent source like CoinGecko or CoinMarketCap. Note the current mid-market price and compare it to the price quoted by your exchange. The difference between these two prices expressed as a percentage is roughly your effective spread.
