If you want long-term investment, then I suggest you choose BTC, ETH, EOS. These are very good choices. If you invest in them, you don't have to worry about them collapsing, and as long as you patiently hold them waiting for the market to pick up, then I believe you can get huge wealth.
Yes, either of the three coins, as long as you patient to hold and wait longer you can have a big profit in the future bacause i believe that the coins will rise soon.
