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.
Of course it is. Nobody likes to pay fees. The smaller the fee is, the better is (unless you are the one that makes a living from earning them fees) When I am withdrawing my coins from an exchange, I always use the crypto with the cheapest withdrawal fee. Binance is making less money but do I give damn? No, because thanks to this decision, I am losing less money. For these reasons, doge and ltc are my favorites lately.
