If credit markets are going to exist within Bitcoin and whether you or I like it or not, they are going to exist within Bitcoin, there needs to be some infrastructure to enable that.

Eventually Bitcoin banking infrastructure will be built out and large enough you won't need to partner with Visa or merchant banks to issue a bitcoin rewards card but we are a ways away from that.

I do think there are other options but they are usually bitcoin and crypto from exchanges. Fold is bitcoin only.
