one question:
when I checkout with ADC using coinpayment,the rate is not 100 sat, it seem like 86 sats, what's up ? how about the bonus?
That's basically your discount

hmmmm, maybe I don't get my head around it, but I'm sure you can buy less with 86 sat than with 100?!?
Better let's put it this way, 1 mil ADC should buy you the same number of BPL as 1 BTC, not as 0.86 BTC
