For low-budget investments, I recommend entering low-risk coins. You should keep a close watch on BNB and ethereum. I can say that you will not be upset if you buy at the right time.
BNB and Eth is good i also believe that those coin can give a huge profit to invetors if they buy and sell on the right time. I also prefer to invest on bitcoin today because I believe that the price will soon rise, there are also so many good altcoins that is now rising because of the bull trend, so i think it is not that hard to earn this time.
