Just check top 20 cmc if you want to find new projects to buy. Rest of them are bullshit mostly
The top 20 projects are the best in this market, but to be honest it won't make you much profit like other altcoins. We should bet a bit on the altcoins outside the top 100 because if the bull run begins its price will increase many times compared to the top altcoins.
That is not true all the time, this depends on the coin you are investing, it's not because they are already in the top 20, we can't expect some significant growth, of course we can still expect, look at xrp, it's in top 3 in the last bull run but it rise big time, and domes other coins in the top 20.
We are just guessing here and we never know what lies ahead so we need to make some good research on the coins we are investing, regardless of what rank they are now.
