Most of altcoins dump from their position after a certain time. And such situation is seen in low potential altcoins. That's why it is need to hold good alcohol so that they won't drop more when market down. Zilla, fantom 2coins are good in my. Besides Sui, Arbitrum, optimism these altcoins are owning layer-two blockchain and their growth good but still cheap in price. So you can check these altcoins for your investment. Hope these altcoins will react good in long run
Just a friendly advice, never have high hopes in altcoins as they may be good for trading or short term investment but not for long term investment as you are already aware that they are so volatile and they can make or break your portfolio anytime. I would suggest Bitcoin is there for long term but yeah you need to have multiple options with proper grouping like a certain altcoins for daily trade especially those which fluctuates between 1% to 3% on daily basis and then some for short term investments (These should be the ones which has hit rock bottom and started rising back). I have had not so pleasant experience with Altcoin hence requesting to DYOR and be upto date with market insights especially about the coins you have invested into do that you can take appropriate decisions at the right time when it matters the most.
