Thats true, if the value is high we are careful not to lose it and instead we are eager to win more because of the price. During that time im hesitating as well to spend my bitcoin in gambling or to make a deposit. Because aside from high transaction fees, im also thinking to be more wise refraining myself to play, unless the btc is already in my gambling account. If I can make my money double then its an achievement however gambling is risky and a game of luck to win so its not easy.
