I don't think there is a smart way to gamble everyone has there own way. Using Bit coins will not be smart because you cant see directly the amount of money you've lost. You need to have lucky that's why it calls gambling.
Agreed with you that luck is very important in Gambling but if we manage and control our game while playing then we can avoid the big losses - at least it can be minimize.
Control yourself and controlling all the aspects of gambling would be the smart way to make profits from gambling. But no ones capable to learn these methods. Even they learn, not capable to apply while gamble at right times.
