Which skill? video editing?  I think it is mediocre   Seriously, what you have shown is just you taking risks.  I don't see any skill there but just luck kicking into your game.  You might end up with a huge loss if that bet goes southward.  So from my observation, it isn't the skill that made you double your bankroll but you just happen to have a lucky day.  But well, if you consider luck as skill then I have nothing to say .  Congratulation on your win btw.
