Well right now the L3+ is not making $650/month. You have to use the most recent number which is the number all the way to the left under "daily" not all the way to the right under "monthly".
I'm based in Southwest FL. Even in the state that is known for it's heat, humidity, and electric rates that aren't low, these things still make really good money.
Like I said I have room for maybe 6-8 L3+'s that I may considering taking in for hosting, just let me know.
I think you're going to make even more money than you think long term. Just a week ago Bitcoin was $2000 cheaper than it is now and I'm expecting at least another $1000 up next year. It's going to be worth running the mine even when it starts to barely break even. You're still going to be getting cheaper coins than people on exchanges
Great setup BTW, just make sure nobody can crawl in through that open window.
While the price of bitcoin is rising, remember these are L3+ machines mining alt coins and not bitcoin, although Nicehash does automatically convert the alt coins it mines into bitcoin which is nice. The price of bitcoin rising does of course help everything overall, the numbers just haven't recently shown too much of a rise in income is all. I will agree with you though, with how efficient these machines are I think I'm going to be keeping them for a long time, until the next most efficient miner is released (smaller nm), and who knows how long that will be.
Also, the window has since been secured. I am running this setup from the same place I live, so I won't go over all of the security I have in place as that would be an opsec fail, much the same way a hacker revealing his network config would be an opsec fail. I will say though that the physical security measures that I have in place are for the protection of would-be burglars, not for the protection of myself.
