Wow, don't tell me you have kept all these coins since 2017 and haven't sold any?
If that was the case, then you missed an opportunity to become rich. It's unfortunate that the altcoins of 2017 are either dead now or the team is no longer active. Only valuable coins such as Wanchain, ICON, Elastos and Quanstamp remain. All cash flow is only being poured into Defi, top coin and Bitcoin projects.
So I recommend that you spend about 1-2 days analyzing the remaining altcoins to see if the team is still active or not. Otherwise, sell all of them and use that money to invest in the top coin, it makes more sense, especially XRP and ETH. The profits you bring will definitely be higher than the altcoins because XRP and ETH's communities are fomo very strong in their coin.
