I thought Provably fair is a 1% house edge?
Being Provably Fair is a myth. But 1% is common in 'provably fairs'.
But I do agree 6% is a terrible edge.
Being provably fair is a
math and has nothing to do with house edge.
It is better to have 6% in provably fair, trusted and respected casino than 0.99% in untrustworthy one.
