you can accumulate more FUN tokens by redeeming your RPs in exchange of free FUN token bonus. take advantage of the opportunity as much as you can. as long as freebitco is here, there's chance for FUN token to increase its value.
Redeeming RP for the FUN token bonus is not profitable, considering that 5 FUN tokens per roll are worth 3k RP. It means that even if you're able to claim this bonus 20 times during the day, you will get only 100 FUN tokens. As for me, it's better to just accumulate 100k RP and exchange it for 100k sats.
Why not accumulate more fun tokens and hope for the increase in price for this token ?
I will prefer to gather as much FUN tokens as possible as i know that they will increase a lot in coming future. If you claim 100K sats, they may be double in value, but fun token has the potential for 4x-5x when then overall marketcap of crypto be be doubled.
