It was 0.20 BTC daily, then they decided to make this 0.30 BTC daily and now 0.50 BTC daily?
Bad news for small coins, many many other markets at Bittrex are in danger right now.
A stable coin with low volume is no bad sign. Exchanges should make fees dependant on volume, flexible between 0.2 (high vol)and 1.0 (low vol) percent.
This is a good idea actually, though 1% on buyer and seller each seems a bit high.
I think it's a good compromise, exchanges have some efforts with administering this. 0.5 BTC volume with 1% fee is around
Edit: selling and buying side together is 200 USD a month, in my example. Ok, perhaps 0.5% is enough.
Bittrex want 50 Dollars fees per month now.
