Has anyone tried this? Principle is pretty simple. You have to buy bomb from previous owner. After that price rises by fixed multiplier. When somebody buys the bomb from you, you make profit. When the bomb has been bought timer starts counting towards zero, owner has 24 hours time to find new buyers or the bomb will explode and he will lose his coins. More expensive bombs allows you to make more profit, if someone buys it. There is also possibility to win instant jackpot.
You can also buy bombs with litecoins.
I think there are other "games" like this one to be found also.
Coinbomb is the bomb!
