There are lots of cryptocurrency payment gateways. Each of them have different processing fees and transaction fees. some of them charge 1% to 5% fees on each transaction. which is a huge amount but merchants have to pay this amount. But there are payment gateways who charge the lowest amount like, one payment gateway only charges 0.23% processing fees on transaction. I find it very attractive because merchants will get more from it and it will be more beneficial for them eventually.
For this reason, a trader must be able to choose and sort coins with low transaction fees. Because we need to take as much advantage as possible with certain tricks. Even traders who always do Arbitrage know the benefits of fees. Personally before I make a withdrawal the first thing to do is to check all crypto withdrawal fees and set it as a favorite option.
