A large amount of investment can not only give you a huge profit but can also give you a huge amount of loss. Apart from a few altcoins, all other altcoins cannot guarantee you that they will surely organize you 10x profit margins for the investment amount. And let's also say one thing that apart from Bitcoin and other prominent Altcoins, the risk of losing is high in other Altcoins, whether it is meme coin, AI or Defi etc.
So it's meant to say that you should invest a huge amount in this coin, which you think can really give you a big amount of profit instead of a big amount of investment. Like Bitcoin or Altcoin has ETH, BNB, SOL etc.
It is left for an investors to know for himself the amount of money he or she can afford to lose and the amount he can not risk losing. There are some rich investors who can risk about $5k in altcoins and for me I can't risk such huge amount. Those rich investors, even if they lose the $5k, it wouldn't affect them and there are some cheap altcoins that you will invest that amount ($5, 000) and if the token pumps, you can earn $50, 000.
Around February this year, I saw a news on binance exchange regarding a trader that used $1k to make $100k just in two hours. So, it is actually the decision of an investor to know how much he or she can risk.
