Has anyone here ever made money gambling with BTC?
Do you mean the admin of the gambling site or the "player" ? Only a few people has made a lot of money on the gambling the site , but all know that at the end is only a question of luck (and the site will win at 99% of the times).
I mean the player. I am doing this because I am tired of seeing posts like "I can't repay my loan for a few days because I lost .xxx BTC gambling", etc. I am trying to show people just how easy it is to lose money gambling, and hard to win.
So, in my opinion, taking out a loan in order to gamble is a big mistake. So is gambling with money you owe someone else. I gamble BTC and I tend to lose more than I win (as is the rule) but I do it with my own money in order to have a little fun playing this or that game. I consider the money I gamble to be the price of the fun and if I win something then it's a bonus. People who are doing what you are saying are being irresponsible, IMO.
