Agreed. It's been getting tighter and tighter on rewards over time. I'd prefer to get 1.5% always and not bother with all the dopamine b.s., personally. I don't want a 1 in a million 1 bitcoin chance. Just run it tight and share back as much as possible with user.

I was using it for 1 or 2 big spends per week, and using all my “spins” on those txs. I pretty much always got 2-3% back that way.
