The catch is that you can not issue a credit card on the blockchain. You need to partner with a traditional financial institution, that will do the due diligence on your company and project. Most of the traditional finances are very cautious when dealing with crypto these days. In my opinion, it is not because they want to preserve the status quo, but mostly because crypto doesn't want to be compliant and it is just too much risk for an established business to deal with crypto companies. Many potential partners of that kind did fall through.
We found that it is much easier to find established partners when you are doing things right organizationally from the very beginning.
