3 sats per roll right now... People used to get 1k every hour in 2013... Everything is so crazy...
Imagine the price of Bitcoin rising until the point newbies are not able to claim any Satoshi at all, except to deposit and wager.
That time, I think we might see a points/ coins system like some faucets have been implementing

Well, at that point, maybe they will go for 1 claim every 2 hours or introduce the 9th decimal digit, but I think this solution is way far more complex.
You're right. Increasing the number of decimal places is the cleanest solution but there are a lot more changes to implement that so we will most likely increase the waiting time as a temporary solution while we're working on it.
