My guess is selling email services to small businesses...
Ok, what we know about this system:
1) you buy a product once and then resell it over and over
2) you will be able to find out if the business needs your product just by looking at their website
3) it is an offline and online technique doing arbitrage
4) then he says "This is more about providing a specific type of service to customers."
5) pretty much the same product as what The Digital Hack Academy is selling on Udemy called, "Work From Home and Earn Passive Income With A Real Business"? - Anyone owns this course?
He sold 25 copies and no one is posting any results.
It sure sounds just like the course you just mebtioned, The fallen one. Very close indeed.
