OmiseGo (OMG) is, in my opinion the best investment right now, it was the fastest to recover in last big fall after China news threw everything into turmoil and now with a buoyant BTC (Bitcoin) price it is primed for new highs.
If you want one to avoid right now, I would say do not jump on ZEC (ZCash) it is way over priced and ready for a big fall. I say this because I do not believe that coindesk articles can keep the volume up on ZEC considering the best privacy coin by a long shot is XMR (Monero) technology wise and DASH is still better than ZEC also. I think this will become common knowledge and sooner or later.
Anyway happy bull times guys. Remember to trade carefully and don't join any disreputable ICOs. Do your research before buying in!
