now I try fixedfloat but 1% fees is too much,
There is a 2nd option there, 0.5% where the amount you'll receive will depend on fluctuations, it will be like a market order in the spot market.
and I also don't understand when I exchange BTC why they charge 30 USD but I'm the one sending the BTC! ?
Who do you think should pay the fees and who should receive them?
