Either way, you are not going to lose here, because the BFG token that you are going to accumulate while playing will become your staking coin, which will earn you 5 tradeable coins, and soon when it hit the market you can sell it, it's like hitting two birds with one stone a new concept where you are not going to lose.
you need to define losing here , if someone is playing for the sake of gambling then yeah you kinda have a point ( except the higher house edge than other sites )
but if you are playing for the sake of getting the tokens ( burning your currency ) then you have tons to lose , pretty much all other sites that shares the same concept ended up listing for much cheaper price than mining costs
playing with BTC here is smarter regarding divs but of course other coins have fans who want to gamble their coins just for the sake of gambling
