It is always hilarious that these amazing high level winners end up betting very very tiny amounts, from small cents to few dollars at most. You don't see people wager 50 bucks on a 1300 odd bet, which would be insane and who would do that but I am sure there are some few super rich people who tries that in the end.
No one would try that silly stunt. Getting 1300x multiplier is less than 0.01% chance so its insane to try it with high amount
Also I saw the multi master and I can say that 15 leg is always a huge drag, but I am sure if we can try hard enough we could one day get it, it is obviously not easy and there is too many complications that could go wrong, we are talking about 15 games obviously it is going to be tough but also if we win just ONE of these, we are there for our bankroll
You dont need to win 15 of those, if you could get the highest winning selection then you would get 300mbtc from that. Everyone that join the multimaster dont really hope that they score 15/15 selection but rather to get the higher number of winning selection. So far there wasnt anyone that has gotten 15/15 yet (?) cmiiw
I am sure I will never have to deposit any money ever again if I win one of these and continue to play with that money (being a gambler is weird, I am not even considering withdrawing

).
Always withdraw what you win, otherwise you wont stop playing.
