Trading and Gambling is totally different things. when someone start gambling must of the gamblers use there fiat money for gamble on the real offline casino. But then they comes on online casino then they buy btc or others currency instant by fiat money and deposit there money on Casino platform. So i don’t think if btc price dump it can impact on gamblers
someone who is a heavy gambler will definitely not mind the price of bitcoin even if it drops because in his mind only how to multiply his money, it is very different from traders who think bitcoin only based on fiat value. so in my opinion, the falling bitcoin price has no impact on the decisions that a gambler will take.
