Karl/Rob,
1) Have you or will you consider crowd-sourcing merchant sign-ups in exchange for incent? I imagine in addition to some of the large clients you've engaged, you'll also need 10s of thousands of smaller merchants onboard to be successful; building in a merchant referral mechanism seem to make a lot of sense for your model.
2) In your AMA video you mention retaining compliance lawyers in Sydney. Have they reviewed the copy on your website? It seems that some of the language there would not be compliant (at least in the US); for example "ICO investors stand to do very well as token value appreciates post launch, driven by merchant demand" and "How can you be so sure that Incent will appreciate in value when merchants go live?". I appreciate your confidence, but I think this needs to be re-worded and balanced with a prominent risk disclosure, to avoid trouble down the road.
