The first rule of crypto and normal investment is simple " invest money which you can afford to lose. "
If you can forget your investments for a long term than do not think just jump in to crypto investment.
Yes, I agree to that. Don't take risk first because you might regret for it in the near future. It is a matter of taking risk because you do not know if the market will fall down or continue rising up. You should play in a safe zone because if you invest all your money and suddenly the ICO fall down, it is a big threat for you. Think wise.
