Most of the time my success on gambling happens when the market is at the bottom or when it is moving bullish. But this doesn't last for a long, so I never think of the market changes when I decide to gamble. I just go gamble, make profit then loss it and further feel bad of losing the hard earned bucks.
Some of us dont mind the price of bitcoin when they gamble, as long as they're in the mood to play regardless of the price then no one can stop. But come to think of it, does the price has something to do in gambling? It cant help us to win. It might hard to use our btc if the price is in bullish since its more profitable to hold (though we can use small quantity with big value already) but for some gamblers the price is not an issue. Currently I dont look at the price, I just gamble wherever I wanted to.
