It's better if you are just going to gamble maybe once a month. It's good that you are doing it occasionally because we may not know if that time will give you profit or lose. You should be cautious when you do gambling because in a single moment all of the btc's that you'd earned can lose immediately. I don't consider this as best source.
What?! I don't understand you! You don't consider gambling as your best source of bitcoin but you are encouraging him to gamble occasionally or atleast once a month? What you are saying is redundant. For me, gambling is not a good source of bitcoin because it is based on pure luck. Instead of earning from it, yiu might lose all of your bitcoin.
Yes, you do really not understand what I said because you haven't read what gembul said. He said, that he is just gambling occasionally and I supported it by saying that it's good for him to gamble for once a month only. And I gave him a warning that he should be aware that even he is gambling occasionally it can still give him a big lose.
