Definitely skill based gambling is more risky. You have to depend on the game fully which can be manipulated easily anytime. And ultimately you have to lose once or even more times. But in trading the case is whole different. Analyzing the market anyone can make money out of it.
I think I need to disagree with you there, it is not that I dont get your point but in my point it is not correct. I really prefer skill based gambling than trading, you can get profits quickly just using your skills. Trading is a really hard thing to deal with especially on these kind of currency, you need to be always alert and really seeks informations concerning your assets.
Skill based gambling do not really need anything, your skill, your money and your experience, while trading there are a lot of needed stuffs like time and passion.
