The distribution model is super dodgy. You have to connect to Facebook messenger and then also give an email address which is never actually used in the process of sending you the book. EDIT: It also opts you in to the messenger subscription, in direct breach of the Facebook usage guidelines. But, I guess, this is a "growth hack". EDIT2: I have absolutely no problem with asking for a messenger...

Really interesting product, what is the backend? Have you considered future scalability of the API endpoint?

So it's like a Baremetrics but for traffic? That's awesome!

Generally best practice with cryptocurrencies is to always use a new address for each transaction. But, if you don't care about that, then this is a good solution. I'm sure you could make the same thing but with it generating a unique address upon each visit fairly easily though so maybe that is something to consider for a later revision?
