Well, it is like you said... I'm not a big fan of "unknown" coins and I avoid to trade them, but I do like to trade some big coins, but on small exchanges... just for fun... :)
Big volume has sense if you are trading with big amounts, but if you trade with smaller amounts, you can try on smaller exchanges, with less volume, as the spread is usually wider, and possible gains bigger... ;)
For example, when steem-hive split happened, I made some nice amount of HIVE trading with the steem/btc and the hive/btc pair on Ionomy...
