75% of crypto investors don't understand that projects like Solana, Cardano, Doge, SAND, XRP, Avalanche did a 100x in this recently past bull run and it will never happen again, not even 20x I believe, those who have been in crypto space since 2017 will understand what im talking about, every four years a new adjustment is always made to Top 20 lists on Coinmarketcap, new breeds will take over.
Get rid of the old stuffs and hunt for the next 100x, not a financial advice but DYOR.
You have a point. These coins who already had a huge pump from the past bullrun might never experience again to increased like 10x of their price. But it doesnt mean it's futile to keep holding these coins (if you have these in your portfolio) just because of that reason. These coins are still good to hold because they're already established and already proven their worth.
Anyway, if you're aiming to have a huge gain on the next bullrun then look for a hidden gem that has real use case and not a shitcoin. It has a chance to increase 10x or more depending on how good the project is and the number of investors believing in it.
