I often exchange it for a 1000% bonus for free spins because I actively use free spins there every hour so I exchange it for a bonus, although maybe I don't use it for 24 hours but I think it's more certain to exchange it for a 1000% bonus or 100% free spins or exchange it for a lottery ticket bonus from every free spin that I do because waiting for 100k IDR is really tedious and takes a very long time to collect it, so taking advantage of it by exchanging the bonus is better and makes sense in my opinion.

But if you are never active in free spins, you should not exchange bonuses because it will definitely harm you and waste your time, you can collect up to 100k as friends in this thread recommend to you, still it also depends on your activity as a user if you are active you will probably collect up to 100k faster but believe me it seems to take a lot longer if I'm not mistaken someone once shared about his account which has reached the point where he has collected 100k RP and exchanged it for BTC, actually I'm also waiting freebitcoin made changes to the minimum RP exchange, for example 10k RP into BTC because the rising BTC might make it difficult for people to exchange it for BTC while the minimum exchange is 100k RP.
