Most of the exchanges have a minimal trading fees of about 0.25%
I see many people discussing trading fees here and there and that how high the trading fees is.
Does 0.25% really make a huge difference if you are earning at least more than 2% ?
It is, we're not always winning in every trade. So it's already 1% in every 4 trades no matter win or lose.
But trading fee is importan to keep the exchange alive because that's the only way they're funding money
