My top 10 under $50 for next year:
1 Gas and NEO
2 Genesis Vision
3 Vertcoin
4 Walton
5 Nebilo
6 Raiden Token Network
7 Ethos
8 Divi Project
9 Dubai Coin
10 Vsync
The ranking doesn’t imply highest gain to lowest, its just a combination of gains and headlines. There isn’t any specific mathematical formula I’m going by. I believe the top 3 will break $50 easy. Don’t forget that only a year ago Ethereum was $14 and Litecoin was $3. We have way more investors in today’s market and thus $50+ is very conservative.
