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.
Yes, there is a huge amount of transaction fees in the world of cryptocurrencies. We pay for the input to the exchange and for the withdrawal from it, and the larger the amount, the higher the fee.
We also lose money on converting courses. Many people here live in countries where the main currency is not the dollar, and they have to convert through it.
A great solution was p2p, when all the above steps are excluded for input and output.
I often use this system for binance, and I am grateful to them for the fact that Binance introduced p2p in the country where I live.
