it's true that investing in altcoin have a bigger risk than Bitcoin, but for now only altcoin can give you a bigger profit than Bitcoin (many altcoin still have the potential that their prices can increase by more than 1000%), therefore there are still many investors who choose to invest in altcoin even though the risk of investing in altcoin is greater than investing in Bitcoin.
Do not assume that all altcoins can increase 1000% but all altcoin increases are only temporary if the bitcoin price has recovered from the correction, it is a big risk if you expect high profits from altcoins even the top altcoins are not a guarantee that the security of assets will still be worth it, you should review luna and ftx coins which has caused losses of up to hundreds and millions of dollars from altcoin investments.
