I guess someone can get lucky after the first try, but others can't get lucky even after 1000 attempts. Nevertheless, slots have a little advantage over in-house(crash, dice) games because you need to wager only 2.5k BTC to get a BFG token.
It's 2,5k satoshis per bfg token, not 2,5k BTC

. But do slots really have an advantage in terms of "mining"? If we compare slots to playing dice with 95% odds. Imho Dice seems the way to go if you really aren't gambling but just mining.
yes we are unable to impose someone's will, maybe we believe the bfg token in the future will be more valuable than expected, yes and of course we like to play, not just mining, there are no restrictions in choice, right?
