I was recently using Cex.io for selling BTC to USD, with a minimum trade in their exchange at 0.001btc.
And I'm now shock to see the minimum trade has gone up to 0.01btc per trade.
Cex.io BTC withdraw fee: 0.001btc
Cex.io BTC minimum can be withdraw is: 0.01btc
If you know any other exchange with low fees please share thanks.
