I just checked, the 1 WOF SPIN / ROLL bonus now costs 720 RP. Does the price of the bonus depend on the bitcoin price, so it has become more expensive, or has Freebitco.in raised the price to reduce the profitability of this boost?
We might have made them a little bit too cheap for the first couple of days. When we add something new there's a bit of guesswork in how popular it will be and therefore what the daily budget will be.
Is there a specific game where you can get reward points?~
Yes. All of them. You get a minimum of 2 RP for every free roll you play, 1 RP for every free roll your referrals play and 1 RP for every 500 Sats you wager.
