Fold Credit Card

I was looking over some details on the Fold credit card and it just didn’t seem very enticing. The example they use on their support page seems wild:

“For example: If you DCA $6,000 per month, you boost your rewards to 2.5% back on the first $2,000 of spend (1.5% Base + 1.0% Tier Bonus). If you also pay your bill in Bitcoin (an additional 0.5%), your total effective reward rate becomes 3%.”

Six thousand dollars a month DCA? How many bitcoins are realistically buying at that level month after month? And that ONLY boosts you to 2.5% back on your fiat spending? Also who tf would ever pay their bills in bitcoin? None of this seems worth my trust, loyalty, and money. Who is this even for?
