What crypto currency would you hold for a 20 year period

I’ve been investing a bit on the usual (BTC, ETH) for a few months and was recently thinking about the long term implication of holding these. I know that it won’t hurt to hold and invest within a 1-2 year period. However, i’m sceptical about the ROI in a decade + hold. What are your positions about this and would you recommend any crypto currency’s that you believe could last?
