I think Bittrex should be removed from that list. Because Bittrex currently no longer offers many good services, they are being strictly controlled by the US government.
The most recent bad event was that they were forced to delist more than 30 alts on their exchanges due to security issues.
It is really a big loss for many investors and the choice is not much anymore.
sooner or later, Bittrex will also go into a dead end.
