So does it mean that the minimum faucet amount of 4 Sat is not the standard for all of the accounts and it varies for those who wager more ?
If we keep more balance in our FreeBitco account, shall we also get a boost in the free bonus ?
It varies for those that wager more + the bonus progress. For me, I get around 36 Sats per roll because I've wagered quite a sum back then.
The amount of sats you get is measured by the ratio of wager-balance. In other words, if you wager more than you earn, your claim amounts increase.
