Used to be super active but got burned by most of the old closures (Cryptsy, btc-e, Bter, etc), so where is the best place to trade nowadays? I have a Coinbase account already along with Kraken but not sure of other options that may be better. Thanks!
There are enough places to trade. You can definitely trade in different places if you want. Before trading you must first decide whether you want to trade alt coin or trade bitcoin. If you want to trade alt coin of course you can trade ethereum. The most reliable coin among alt coin is ethereum you can trade ethereum if you want.
