As which coin i need to invest in it.
ETH and BNB are altcoins which in my opinion have very good potential lately, especially altcoin BNB really shows a significant increase, many investors are investing BNB and many traders are trading these coins.
Hopefully you've got profit from them. ETH is always consider will be the best altcoin because its platform has been producing a lot of project that currently used by many user. You may not supprised about it but when there is newbie who hasn't know ETH before then after they know it they will supprised and will be choose ETH as their investment place. Regarding BNB, it also potential coin given its trading platform has been using by most crypto user. Even if you ask someone here where you should trade cryptocurrency I'm sure they will answer binance exchange to suggested you.
