i transfered eth here to buy OTN. Sold them later for btc. then i sold the btc fur usdt. now i want to place an buy order, but the system tell me uncificient funds....any idea what im doing wrong?
ps i have 900+ usdt
edit: i just figured out, that i cant use my whole USDT but have to leave some in order to place an order. why is that?
I'm pretty new here - but I believe you have to leave enough to cover the trade fees of the buy order.
