Well OP it depends if you want to make money or not. Investing tiny amounts here and there i guess could be a hobby. But dont expect to make anything. Trading as a hobby expect to lose a lot of money.
It one of the most competitive professional environments you can enter. If you want to make money it has to be a profession. I started off doing it as a hobby in my late teens. Lost money all the time. Then eventually started working for professional trading firms. 12 years on it has been my full time career for 10 years. Don't believe the hype about people relaxing by the pool monitoring their positions. To make it you need to be dedicated 12+ hours a day studying, watching and learning.
