I am a big supporter of using bank issued debit cards for on-ramp functions!! Allowing debit cards would be easier and faster than the 1 - 3 day wait for ACH. I too would bring all my business to Spritz if the debit card option was offered, especially if the fees were a little less than fees on other exchanges that allow debit cards for on-ramping.

A BIG YES from me... US , UK & Europe please.

Yes, definitley very useful. I would use it also, BIG time.

If you offered this service with cheaper rates than other exchanges. I would give you all my business
