Whatever the problems are for the delay of ETH 2.0, it deserves our waiting time. People (investors) who have enough patience and determination to keep holding ETH will get sweety profits later. It might take a few months to hit the profit-taking line but it deserves waiting time.

Please tell me which one (over thousands of altcoins/tokens) deserves the second position (a solid second position) in crypto? If it is not Ethereum, please tell me.

Vitalik is a kind of perfectionist and maybe he would prefer to prepare a perfect ETH 2.0.
