Feeling sad, looking for a place where I can gamble the last of my stack.
What sites can I gamble 50% BTC and double or nothing?
What makes you feel sad? Losing? Try to use the money you can afford to lose to gamble or best not to gamble at all if you can not.
You want to gamble with 50 BTC, that is too high. Or you want a gambling site that you want to gamble and either win or lose 50%. No gambling site can offer that direct because they offer more than that, you can see variety of options and bets and different odds, but know that the more the odds, the more the chance of losing, but yet you can win, but gamble with what you can afford to lose. You can try
