We're not going to devalue RP because you earn 1 RP per 500 Sats wagered so it's pegged purely in BTC. If the price keeps increasing we might have to reduce how many we give for free rolls.
That's good news, was stacking my RP points and I was afraid their exchange rate was going down (a few years ago we could exchange 1RP for 2 sats)
Maybe add a bonus for regular gamblers/betters similar to the bonus on free rolls.
