it seems that what you say is the best according to your response and we can not hinder the analysis that you may have also done, because it is asked to provide alternative options.

but I partially agree with you but the most important of the existing coins is bitcoin and ethereum, because they are both now kings and queens of crypto coins.

For altcoins, all the coins in the top rankings are very potential for investment, I am even interested in chainlink, LTC, Binance, TRX for other alternatives. all of them will definitely have their own version in determining which is appropriate and it is reasonable that the top ranked coin is not a newly growing coin.
