Yes, Ethereum is best. Because
Despite the current Ethereum price level and decreasing trend over the last few months, long-term predictions seem rather positive. According to Longforecast, Ethereum will hit $724 USD by the end of 2020. Experts state that the price could range between $474 USD and $672 USD over the next few months.
A very large number of projects have been built on Ethereum, a lot of smart contracts have been made, but I am still repelled by such large commissions from this Blockchain, Buterin could come up with something to reduce the price for gas, I do not understand why he will not do so.
