Bitcoin's will surely have good days ahead post halving but which will be the most valuable altcoin for 2020? I vouch on Ethereum and Tron but I would like to know expert's opinion as it would help other members while choosing their altcoin investment as altcoin does pump along with bitcoin so those who cannot afford to invest into bitcoin can invest into altcoins.
I will be for Ethereum and Ripple mate as i am sure that the number 2 currency will spike together with bitcoin next year and Ripple as centralized currency will make another way just like what he did last year.
IMO ADA - Cardano in 5-10 years will be unbeatable!
if you only care reading OP?for sure you will find that the question is only for 2020 and not for 5-10 years that you are mentioning mate.
