One half of one percent? Still pretty significant. I use about 4 grand usd a month on my paypal mastercard, which returns 1% cashback and I get nice fat deposits every month of almost 50 bucks sometimes.

In bitcoin, 0.5% would be 25 bucks worth of bitcoin on that same math, so thats not insignificant at ALL, if it's stored as bitcoin and not a spot price cash rebate. Meaning the btc can than sit and increase in value, as opposed to being statically valued at the time of the rebate.

Not bad card, not bad.
