Investment needs to be diversified. Many forum users have suggested diversifying the portfolio. I would also agree with them. Because there are always risks in cryptocurrency. If we talk about Luna Crash event of 2022 where lots of investors are completely bankrupt because they keep their entire investment in just one project. If there was variation there would not be situation like Bankruptcy. Many investors never imagined that a project like Luna suddenly collapse. Since there is no assurance of any top-level project in altcoins, so investment diversification is essential for all the investors.
Yes mate you are right that it is always high risk to trading or investment with Cryptocurrencies. I will also agree with you on this point that is investment should diversified but in this case if any person wanna do investment only on bitcoin then I also think that it can be also beneficial the thing investor have to hold it for long term . In my personal opinion I think it is more safe to investment on only bitcoin without going to alt-coins. And I think the more alternative coins you invest in, the more risk and effort you'll need.
