Still ethereum is most promising coin. ethereum will be the best Crypto coin I think after 2023. Bitcoins are still hard to beat, but in the future bitcoin and ethereum will not make much difference, they will be almost the same in terms of development projects. I hope to be born a new altcoin capable of splitting both and causing market chaos.
Ethereum is how a lot of the traders on this forum like to use for their portfolio. The coin is an easy investment.
