If you take a look at the cryptocurrency market you'll notice that it's a difficult time at the moment,only the bitcoin and other good coins will survive.
Investors should be wise and take note of projects they put their money into
There were shitcoins before, now the only difference is that there is much more shitcoins! There will always be some shitcoins, projects without perspective, wrong ideas, wrong realization, many things can go wrong. I agree with op about one thing, this downtrend market will cut many coins very hard, and many will not be able to recover from that fall, some will get out even stronger, on us is to choose coins. I must agree with you about bitcoin, bitcoin will survive, like many others, market will definitely grow, just top 100 coins in 5 years will look different from now.
