When I read the title I though you manage to profit due to a bonus, which is normally hard in casino, but I guess it was a normal win.
Congratulations on your wins, although I would be much happier if the profit was related to a deposit bonus, and not just luck, because that way I would probably be able to do it as well xD
Yes the title looks like the OP made that much amount of deposit bonus, I think many people are confused like us. He really lucky guy made a huge profit in slot games.
You played slots, and just on slots, you can earn so much in so short period. But trust me when I say on slots its easy to lose much more then 0.1 btc very fast. I see OP lost at mbitcasino, once I lost around 0.2 btc in 10 minutes, in that time I had maybe 10 win spins with 10% from bet payout, that means nothing and like that to the end, I was disappointed, and I never went there again.
Congratulations for win, I know how nice it feels when you make nice amount on slots, I love it. Slots are expensive to play, and even I play sometimes with very small bankroll that isn`t that, for slots you need a lot of money to be able to miss, miss, miss and then raise bets and miss and raise bets and when you hit the bonus you get all back with very nice reward.
Yes the slots are too much expensive without knowing us we will lose our money in this games. Every win will make us spend more time in these games. But finally, we end up with a big loss. I never had this type of lucky day in my life. Congrats OP.
