My choice from the one you gave is that I will not use the 1 BTC I have just to gamble whatever the reward offer is as big as whatever the reward is, I will not use it to gamble. if for spot trading is ok.
gambling is a gambling and then when you give me such amount of BTC to enroll in gambling I don't think that I can use such values of BTC or amount of BTC to gamble because I know quite well that the dumpling is all about a risk and it is come the profitable by you or you lose whatever thing you have if I have such opportunity to gamble with the such amount of bitcoin I think that I will divide it into three and take one part of it to gamble in case if the gambling is against me then I will still have something to make use of it weather I use it for investment or I use it for driving I think that will be more profitable for me than using everything that I've been issues to me to gamble at once
