Very cheap GPUs, great deal, you will ROI very fast because you don't need to make 100% ROI, the GPUs have resale value.
From a tax accounting perspective any sold GPU will have to be reclaimed by IRS if you took an equipment deduction tax benefit. Best to run them down to the ground. Geez you small time miners are amatures.
If the market goes up. Not only you have to Roi on dollar amount. You must also roi on crypto coin amount if someone sold their coins to buy gear.
If dollar amount is roi but crypto coin amount did not roi then you lose bc of miss opportunity of just holding coin would have offered better gains.
This does not apply to him since he took a 16 percent loan as a hedge in case market goes up he keeps his coin gains but pays a 16 percent interest as insurance if market goes up.
If market goes down and stays bear longer like over a year than best if he did not take a loan and just sold to hard cash for hardware or just kept his cash to buy coins lower
^ This. All equipment can be depreciated but then if you sell it, it has to be sold at "fair market value" then detected as income. I'm not an expert on how that all works. That's pretty much my plan run these babies until they die and dump them at E-waste. Considering ROI time, and possible crypto-booms I'm really hoping for good income from them even after they can't mine Ethereum anymore.
Updated the OP with more rig pictures build in progress. Another 52 cards are enroute and P104-100s are racked! Currently testing 13x RX470s and 13x P104-100s.
Rx470 8gb why not ?
because when you're dealing with 150+ GPUs that's an increase of cost in thousands of dollars. RX470 4GB's offer the lowest cost and still perform well-meaning faster ROI.
