In my experiences, I already won but a little amount of BTC only betting on a boxing fight which is Pacquiao-Thurman fight.
Now can I ask you, did you ever won a huge amount of money on gambling?

The term
HUGE is relative depending on the circumstances of an individual which cannot be the same to all classes.
As to my experience, back when Dota 2 has KEYS as their main currency in the market (dota2lounge.com), I started with 0 keys and ended up with ~35 keys in the market due to betting to a bot. But when I slowly started losing my keys on by one, I tried betting all of my remaining keys which doubled my initial amount. From that experience, I vowed to stop and gamble with a limitation on my mind.
On the other hand, my father used to practice cockfighting as we have a farm specifically for breeding and fighting chickens. I remembered my father won around $2,000 from one fight alone and won all the remaining fights (he had a total of 5 fights).
