Seems crazy to me that anybody who has 100k RP would do anything except exchange it for Bitcoin.

There is no way I'd trust FBC to give me any of the "gifts" you can cash out the RP for. The chances of them physically shipping something these day is next to 0.

Then, the numbers don't stack up if you exchange RP for free spin bonuses (such as 10x reward one), it still works out better to just exchange for RP. 100k RP = 100,000 sats which is just under $100 these days.
