For sure OmiseGO is great!! Backed by huge names, and has everything going for it. Excellent investment choice. For it to reach $20 per OMG token it will need to triple from where it's now. At a current market cap of 600 million, that should put it at a market cap three times bigger: 1.8 billion. I don't see it today since that would put it higher than NEO at this moment. But I definitely see a 1 billion market cap in the near future, and upwards to your estimation if we give it a few more months.
Check out TenX quick too by the way. That train is leaving but you can still get on if you're quick.
I got already is gonna be good profit on that one on long term as well
