He won the same sized bet like this last time, I wish it was PR because he won 83btc last time if i remember correctly

.
so this is the same person as the last time?
but i just wondering how much the maximum bet that stake has? because right now i just try to make the same bet as his but the max bet i got just under 5 btc
AFAİK, the recent terms&conditions refer to 8
BTC limit for potential profit in single bet. You can read more on the forum of Stake.
