Any ideas why this happened? I used to have more, 5 or even 7, but missed the moment when it reduced to 2.
Claiming from the faucet as well as redeeming Wheel of Fortune spins will negatively affect the ratio needed to maintain the base reward at $0.002 worth of sats. Your BTC balance also factors into whether your reward is reduced. I believe if you have over $100 worth in your account then you will have the normal base reward, but the requirement is lower depending on how much you've wagered.
