Is it realy this easy to make money?

hi:), im complety new to stocks and stuff, and tried Pluss500. Its CFD kind of thing.

But is there a catch? it just seems to easy to be true.

I bought some oil stocks and then it started to rise and i earned almost 1800 $ the same day.



i just wanna know if theres something hidden that i dont know, i dont wanna get in debt and suddenly own someone alot of money
