Thanks. You make a good point about the rewards. I thought 1% could be a decent estimate given that not everyone pays attention, some points are never redeemed and rewards over 1% are usually only for specific purchase types (e.g., gas). But I may very well have underestimated this. And if people do redeem at a 90%+ rate, then they will definitely notice if there are no rewards on the Bitcoin side.
Very interesting.
