In my opinion, investing in altcoins is equally risky, even the top altcoins such as Luna or FTT have collapsed quickly, it cannot be said that the top 100 coins will guarantee your safety. Apart from bitcoin, I think we should remove all old altcoins from our portfolio. Perhaps ETH and BNB are the altcoins to hold and the rest is better to stay away from them. After the death of FTT this time, I started to lose faith when investing in bear season altcoins including top altcoins.
