Well, first of all, crypto invesment is likely look gambling. Just be sure to know on when you sell your crypto or just leave crypto investment whenever you get your profit.
Well to be honest the way most people "invest in crypto" it really is a form of gambling. I can even admit that when I invested in a couple of ICOs (oh trust me I learn my lesson well), I was gambling on a few things. Gambling that the guys wouldn't run away with my money, gambling that the guys would do what they said they would do, and gambling that people wouldn't dump their tokens when it got listed.
I usually lost on 1 point.
