You need to know your limits. Don't gamble with money or bitcoins that you need. Put a stop loss level if you dont have a control on yourself
Indeed when you know your limits you can gamble on a safe way and than gambling is also not bad at all in my eyes.
Gambling is only wrong when you are doing it on a wrong way and this means that you are addicted to it mostly.
In my opinion gambling is wrong when it mess your life .
I mean most gambler get addicted and do everything to bet again and again even they have reached the limit of their bankroll. I will not suggest anybody to gamble if they have not a good attitude to stop when they hit the big loss.
My opinions is same with you, actually i believe it, if you are strong person, than you should play gambling, other wise avoid it, and that is better for us.
My play of gambling style is that whenever i am play and i win it that i play it again and when i lose it so on the sport i stop the bets, that is my trick and in this way i never feel sad, and for me gambling is good opportunity to get profit in a short time.
