Bitshares DEX is 0% fee to withdraw
0.07 BTS fee to trade, that's $0.063 - and that is currently HIGH because of the increase in BTS (what like 500 or 600% since the beginning of this year? Fees get adjusted once a quarter. Bitshares was paying its witnesses plenty when fees were much lower.
Decentralized? Yes. Low trading fees? Yes. Withdrawal limits? No.
The only reason why we don't have volume is because "the uneducated" wont trade there... idk out of stupidity?
