your questions are difficult to answer with certainty will get a profit, just do what you think is good, but I invested the BNB and Link because I felt the BNB had enough potential in the future.
actually there are many coins that are suitable for investment one like the coin that you mentioned BNB, BNB are pretty good if you look at their developments and the price is not too expensive Other coins are on ethereum, Ethereum movement is fast enough and the price hasn't reached its maximum yet ethereum likely will rise again from the current price
there are a lot of options, but the OP should learn how to choose on his own. for sure, there are alts worth looking at, but he should know the risks involved. if he will assess each alt that he wants to venture with and not just because someone else suggested him, at least he's doing his part. no one but him is to blame him for whatever may happen to his funds. just remember that. at the end of the day, it is only him that can take care of his portfolio. won't suggest any alt as it is for him to decide on this stuff.
