Also try investing on EOS and AION this two coins would probably give you profit after 1-2 years from now. There are also a lot of coins out there, just try to have research first if your looking for other coins.
Bitcoin and Ethereum is the best if you don't want to regret in the future.
Would you really suggest btc at this point? It's been really unstable this month I think so far. I think it was a really good investment at around 9-10k$ but Idk about now.
