If you really want to make money then find a decent job, or build your own business. Gambling can never be a source of income. The question is, how often do you gamble this year? Is there any fund which is intended only in gambling? Do you empty it and get on other funds? Do you quit when its time to quit? If you dont have discipline then most likely you will fail. 10 BTC is hige and its impossible that you didnt win with all that stuff.
Very well said! Gambling should only be for fun and not a full time job because we already know it is pure luck, no matter what you do the chance of winning is low and don't gamble most especially if you don't have the resources to do it. I think this is very common to most people who are desperate in having a better living, they tend to gamble in the hope to win and double the money but failed to realized the consequences of gambling and worst case is they get easily addicted to gambling. Self discipline on the other hand, is indeed very important because if you don't have discipline you'll become greedy and probably lose everything as a result.
