I would say ETH. I’ve been holding ETH since January 2020 when it was still between $180 to $200. When ETH reached a then-all time high of $4,500+, it could have been my chance to sell it at a good profit. However, I choose to HODL for a long while no matter what. I still believe that it could go even much higher. $4,500+ isn’t enough.
ETH still has yet to launch the consensus layer (ditching the 2.0), which could be the ultimate game-changer for us to eliminate these exorbitant gas fees. This is what I am going to hold until 2023 or so.
