For me the confusion is whether SPT take on the credit risk upfront and then pay the merchant a discounted amount (like APT) or do they pay merchants over time in instalments In the Forbes report, it states the former but in a lot of the posts here on HC, it suggests the later. Both scenarios offer different risks for SPT and the merchants and this obviously impacts how popular, ease to replicate, credit risks, etc impacting both parties. One thing for sure SPT has obviously not clearly laid this out like APT.
