Coinbase doesn’t charge you any markup fee — but there’s some inevitable spread. And with some obscure trading pairs (exchanging ZRX for BCH for instance), you might end up paying around 1 percent in spread. Still, it’s a much better user experience for those who just want to trade on Coinbase. If you buy or sell less than 200 USD or equivalent, fees get much more expensive. For instance, a $10 order will generate $0.99 in fees, or 9.9 percent.
Fees are even higher if you’re using a credit or debit card. Without even mentioning other exchanges, Coinbase Pro users have been able to trade between multiple cryptocurrencies for a long time. But Coinbase is still the entry gate for many new cryptocurrency users. But the good news is that it’s a completely different story with token-to-token transactions.
