I don't remember exactly how long it took to accumulate those 2360 spins. I already had some spins stored before hiting the full tier level of premium program which guaranteed an income of 15 spins a day since then.
Considering 15 spins a day it would take almost 158 days, but as I was receiving less before, I guess it must have took something near 170-180 days.
I expect more 5000 RPs and satoshis rewards, plus a few more GTs.
Now with the BTC price still at sideways, I'd rather keep my spins as well.
