Interesting point. I'm in the US and BitTrex is located in Las Vegas. Yea, some coins work fine and others don't . If that's the case BitTrex should give a different error stating the true issue.
Most of the coins I have with this issue with are on the KuCoin exchange so I'll be uploading there if I want to get rid of some. With the recent run up I'm trying to trim my coins by 5-10% to lock in profits.
Thanks for the info :)
Cheers.
Yeah I think I'm going to register with KuCoin now.
