Of the thousands of altcoins on the market, most are risky. Yes there are still some alt coins, from which there is a good chance to earn money.  There is also another special factor that is the price of altcoins, many people are still involved in investing in altcoins due to the low prices. I think some of the best altcoins worth considering as an investment are Ethereum, BNB, Litecoin, Solana among the top alt coins. These coins are well known and old coins in the market. I think atleast you won't lose money if you invest in mentioned coins instead of investing in crap altcoins.
