I'm surprised you're included XRP as stable enough coin, did you forget XRP got lawsuit and few big exchanges already delisted XRP on previous year? [1] Literally XRP is centralized coin and doesn't deserve to listed on top 10 crypto.

Most of altcoins will become deadcoins aka worthless, you can't do anything since the exchanges didn't list those deadcoins anymore and no one will interested to buy your coins in Dapps or P2P. But Bitcoin is the only exception coin that high likely wouldn't become deadcoin due to it's security and decentralization as the main purpose of Bitcoin.
