If Bitcoin price reaches 150k dollars, I don't think that I will continue to bet. I have enough Bitcoin to be rich in a situation like that. I wouldn't need to bet anymore.
That's a new perspective..
But I guess that also rises a new question. Are you actually gambling to increase the number of your Bitcoins that you are holding or you are actually doing it for fun? Habit or not if your answer on the first question is yes I guess you would still continue to bet despite the price increase.
