This is ridiculous. Rent a 300 dollar video card for 300 dollars, make profit?
Why wouldn't you just mine yourself, and KEEP the profit?
I don't understand how this sort of altruism COULDNT be a scam.
Additionally, your prospective client could use the 300 bucks to buy another videocard and slap it into his rig.
What you're literally asking for is "give me 300 dollars and I'll print you 450 dollars. Wow!"
if that was reasonable, at all, you would just print the cash yourself, and keep it.
This doesn't make sense.
From what I gather, this is a good way for him to secure the initial investment of the miners while hedging against unprofitability in the realm of mining. He agrees to take a smaller cut of what he is expecting to mine to be guaranteed to get at least x amount of dollars for his investment.
A reasonable 7950x3 system should cost around $1500 to $1600, so if he rents them out for $250/mo with a 6-month lockin, he would be able to pay for the rig upfront. After that six months, if that person leaves, he could essentially mine with free hardware. If they stay on, he still makes low-risk money.
