Would you gamble on casino games that are based around the real fluctuations of BTC's price?
Definitely some people will prefer to gamble on the price fluctuations of bitcoin price. I have also seen it on two other gambling site before.
But as for me, I will prefer no to do that. I will prefer to go for perpetual future trading which is what that I prefer and not actually gambling like the binary like ones like betting on fluctuations of bitcoin price
