I’m not sure if totally understand the business case - could you restate it more clearly?
By “Mining” you mean “Farming”, which means you’d already have a farm full of plots ready to go, let’s say 1 PiB. Let’s say that cost you $15,000 in hardware to build and plot over a 3 month period of time.
Now you sell a portion of the rights to the XCH that farm generates a day/week/month… so I’m giving you say $1,000 for some % of the XCH.
So as long as the XCH I get from you for my $1,000 is cheaper than the XCH I could BUY from HashGreen or Farm myself - then it works, right?
