The average daily trading volume warning on Bittrex has come up almost every month for the past two years or so.. I wouldn't worry about it as much because it's a mechanism they have in place for every market there. The trading volume of filled orders is what this mechanism looks for. That's why I think you shouldn't have to worry or risk your coins. Make trades between exchanges, instead! Putting those coins to use. If you're careful you can make some profit while doing so.
