If you are holding for a long term it's not gambling. And keep in mind that if you are starting with a big budget that's more profitable. But if you are day trading (by following signals or doing your own technical analysis on the price chart or the company profile) it is going to be a little bit more risky, but if u are more cautious and you really understand what is going on.. u can definitely make some descent money with it. For the gambling part.. it is not gambling if u know what u are doing. But if u just follow some hype or rumor.. its gambling. I recommend u learn doing deep technical analysis on price charts and keep yourself updated.. that way you can make money. Lot of it.
