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?
All you have to do is bet on black or red in roulette. It's not exactly 50/50 as it still there is zero as a separate color, but the odds don't change much. Roulette is available at most casinos, so just pick your favorite platform or the one that gives you the biggest welcome bonus.
My question is where I can do this for 50 BTC
If you like old school on-chain gambling, you may give a try to
Chain-Bet.com. It is not on Bitcoin blockchain anymore though. Due to Bitcoin network clogging, it now operates on Litecoin network. Also, due to low bankroll, you can not bet anywhere close to 50 BTC worth LTC on it now. Try it and if you love it, you may invest in the bankroll. Increasing bankroll will allow me to elevate bet size.
By the way,
Chain-Bet.com is 15x or nothing.
