It`s risky, and like most others risky activities this one is very interesting and can bring some profit to you if you do everything good. Into unknown you don`t rush with full power, start slowly with little amounts that you can afford to lose, while you practice trading take some time for reading about it, learning about it, try to be involved in some telegram groups where you can talk with others and share your experience, same like you do here. I always say preparation and making plans before is necessary for making profit, you can have luck couple times, but trades you plan are always better then lucky guessing and picking random coins.
