I also gambled too much when I was new to gambling but fortunately now I deposit very less and bet that much only.
Actually with time I have matured with gambling, the mistake was to not save the bitcoins and gambling them. Really I have lost over 6 bitcoins overall man and I just don't know why I lost that. I was way toooo confident when I was new to gambling.
Yes, losing 6 BTC is quite unfortunate, even in a long period of time. But it's good to see that you were not completely affected by it, and manage to create a good mind set, and didn't end up chasing losses etc. With a little luck maybe you can win that same amount now, and if not, you are at least enjoying it, and doing it in a healthy manner.
