I stopped using Bittrex when they limited my withdrawls to something like $100 a day. I knew soon it'd be a full stop, and I made sure to withdraw anything I had. I'm using Cryptopia right now. They do have "verification" unfortunately, but unverified accounts can withdraw up to $5,000. I'm happy with that, but I also don't keep money on exchanges. I only use it for a quick buy or sale. So, if they do limit me in the future I'll just go some place else.
