There is no doubt Bitcoin, ETH, BNB is a good long term investment.  You can also try to look at UTK, ADA, Matic, DOT, Uniswap, Cake and many more.  The second list of token is yet to be pumped hard and has a very promising future.  Their developer is very active and they have their own innovations that they can put on the table.  But a word of advice, never fully trust any suggestion here until you have verified it yourself.
