Very good suggestion given by our friend, who are already willing to help. Indeed, it must be admitted that the Binance exchange is the best at the moment and you can use it as an alternative if you don't have a clue what is the best altcoin token to invest in for you. or you can also use CMC and Coingecko which are at the top of the rankings if you want to be an investment.

If I stick to the first altcoin, ethereum really deserves to be a very attractive investment to date, if there are others it might be chainlink, XRP and others. You can analyze yourself to choose among those described above.
try Litecoin and BNB also ,for safer and long term investment.
