Before I realized all gambling does is give you some thrills and fun, I was into it for money. Yeah I know it sounds silly now but at the time I really tough I could win it all and now looking back on it I realize it is silly and stupid. At the time I didn't know what martingale was and how it could lose you everything but I saw it as something that might work.
I had about 1 bitcoin (well back in the day it was easier to own 1 bitcoin, I made 0.2 of it just by mining with my old laptop) and I gambled with it, I made it up to 2.2 bitcoin for a while before it all crashing down when I lost back to back in a row couple times and all was gone. Since than I didn't stop gambling but I realize it is something to have fun with and accept the loss even before starting gambling.
It is even a good thing that you were able to quickly get the real picture before things ended up getting out of hand. The thing with gambling is that it gets you to be comfortable with winning when you start and then the house edge picks on you all of a sudden and then you see yourself getting into some deep shit eventually.
Gambling addictions stories started from the mentality of the person involved and with the wrong one, it is always a bad experience at the end.
