If I have enough money then I will only buy as many ethereum coins as possible. I only chose ethereum because I think ethereum is the most potential coin in the future. Ethereum has proven its benefits significantly especially in helping ICOs. ICO can easily create a blockchain-based application or project by riding on the ethereum blockchain. I am sure that the longer the community will be aware of the benefits brought by ethereum. When this awareness arises, the popularity and public trust in ethereum will be even higher. This will certainly be followed by higher ethereum prices. I am sure that when that situation is reached, ethereum can become the king of crypto currencies.
