edit:
I just checked, the 1 WOF SPIN / ROLL bonus now costs 720 RP. Does the price of the bonus depend on the bitcoin price, so it has become more expensive, or has Freebitco.in raised the price to reduce the profitability of this boost?
I guess the second part is correct. It wouldn't make sense to increase the price because BTC prize has increased as the rewards you win on the WOF spin are lower with a higher BTC prize...
I also bought the 2 spins/hour and must say so far so bad.
2 times min satoshi and in 12 (!!) other spins only lottery tickets, 8 in a row min tickets of 32. Thats the least thing I was hoping for.
That's how it can go unfortunately, also have had that multiple times. Keep spinning and with some luck you will be able to score some higher satoshi (or RP) wins.
