There is no doubt my favorite altcoin is the NEO, I bought them when the price is $0.5 and I sold a half of them when the price is $50, 100x profit, that is the reason.
Wow that is quite the haul. I didn't get into Neo until just recently and I still don't have a lot
For me my favourite alt coin is stratis and ethereum - I think they will take off even more by end of year
