Well, at least you don't need money right now so you'll be ok when the price goes down which is good. 5-10 years for holding crypto is a good plan, make sure to hold them in the safest wallet or something that you can control the private key. Don't put them in exchange because anything can happen especially in 5-10 years, we've seen many exchanges got hacked or even vanished in the past. I see some people still holding their assets in exchange for the long term which is totally bad.
