For both platforms we can make a distinction in the level of fees granted to transactions, start with poloniex which determines the fees according to the evolution of your trading over a month and taking into account your assigned status as maker or taker . Fees are low for decision makers because they provide liquidity. If for example you are trading less than 600 BTC, Poloniex will add a 0.15% decision maker fee or 0.25% taker fee to your trade.

Coinbase, its fees are its weak point and the supreme argument traders use against this trading platform. It is based on both the trade amount and the payment method you have chosen. For transactions under $ 200, a fixed fee applies regardless of the service payment method.

The fees are as follows:

$ 0.99 for a transaction valued at $ 10.99 or less
$ 1.49 for a transaction valued at $ 11.00 to $ 26.49
$ 1.99 for a transaction valued at $ 26.50 to $ 51.99
$ 2.99 for a transaction valued at $ 52.00 to $ 78.05
