Okay I have a m50 with a dead dashboard 2200 watts and 75 th is 2200/75 = 29.3 watts a th
[...]
So with luck I end up with 2 one board m50's .
They will need 220-250 volt power
Maybe 28th at 800 watts
they would be a decent home miner.
I will start a thread on this in a week
The efficiency figures looks good, but I'm sure for anyone just getting started, this would be a much bigger initial investment (since you brought up the Avalon Nano 3 price) and ~10x higher power bill, right? I don't fully get your point about the price.
We should keep in mind that if someone's 'losing' money compared to DCA with a 29J/TH 100W Avalon, they're going to lose proportionally as much with a 29J/TH M50.
I.e. if you pay $15 in electricity for $9 in BTC with the Nano 3, you're at a -40% loss, but it's just 6 bucks; with 8x the power and hashrate, you pay $150 a month for $90 in BTC ($60 loss) - same proportionally, but a lot more real money 'lost' each month.
