In my opinion, the best coin used as an investment medium is ethereum. I think only ethereum has high success potential. It is very possible that in the next two years, ethereum can get a 50-fold profit. I can say this because ethereum brings almost perfect technology. Technologically, ethereum is the most powerful and great. Almost all ICOs use the ethereum blockchain platform to run their projects so I am sure that in the future there will be higher ethereum opportunities for more ICOs to be used and also more fans. When it arrived, ethereum would be sought after and the price would skyrocket.
