Just to ask, where you do get those funds/BTC to pay up on that jackpot.? Assuming that people are mostly getting up some MBL to bet came from free??
Well, the MBL to my knowledge is a play money ETH-token creation based on nothing (since it has no exchange market). Technically, anyone could generate any amount of play money by creating any token. In this particular case, the devs may have just awarded themselves billions or trillions of MBL for all I know. I haven't looked at the smart contract, don't care to do so either.
The BTC is generated from the sales of the MBL play money. The odds of winning is so small that they will virtually never have to pay out in this real money (2 BTC) anyway either.
It's got to be like a 99.999% house edge I'm guessing, give or take a couple zeroes in either direction (not exaggerating either).
