I would say its pretty risky. I would also say put SOME not ALL of it in btc/eth/alt coins and the rest in stocks, bonds, etc. Its good to have a bunch of various different ways of storing value. Everyone has their own risk tolerance and preference as well so keep that in to consideration. If youre younger you generally have a high risk tolerance since you are able to make it up later. If you are old you tend to be more conservative.
