There is no strategy that works in gambling to achieve the profit but there are some to limit the loss.One which i have noticed that never keep your bitcoins in gambling sites or casinos,if they are there you will gamble if dont even want to,only deposit there when you are ready for it and feel that you can be bit lucky.
There is really no wreck proof strategies when it comes to gambling - but, it is ideal to have a strategy or should I see strategies than don't have any strategies at all and just bet in random. Hence, I would suggest, if you really want to do good with gambling, you better first decide for yourself that you are willing to spend most of your time during the day and night learning strategies just like what pro gamblers does.
figuring out about what strategy could be used and work/give you a profit in gambling are not a smart way to gamble as so far there is no proof a strategy give people profit in the long run especially in a casino games . just gamble for fun never make it as a money maker and stake the amount that you can affor to lose.
