In that case it does not really matter if you go L3+ or D3. Its more a situation of "Am I getting Miners at all". You could even go for a much cheaper S9. ROI on a S9 will be roughly the same since Difficulty does not fluctuate as fast as the new L3/D3
But are you sure you mean 0,003 per kWh? Don't you mean 0,03?
Anyway if its really that much for electricity costs, it will take age for the electricity to be more expensive than the earnings of the individual machine.
No $0.003 is the cost not $0.03 - no mistake there my friend
I see you wrote only ASIC machines, no GPU machines at all?
I don't have any experience with GPU after 2012. I don't even know what brand got the most efficient cards right now.
But yeah that might be something you want to look into as well.
In the end it got 2 factors:
1) What do you wanna mine?
2) What is the cost of mining?
When you got such a ridiculous low cost of electricity, you can run the miners ASIC or GPU until the day of dawn. Most people need to upgrade to better models because daily costs are higher than the income. In your case costs are so low that even with huge difficulty every miner you operate will make money (even when the next gen ASIC miner is released)
If you want to mine ETH or MONERO or something else you need GPU. But you could also buy a L3+/D3/S9 and use prohashing. Then get a payout in whatever currency you like.
I would di that in case you don't want to tweak with GPUs and the building time. ASICS are in the end plug and play and easy to use. If you can get your hands on them, it might be worth the "extra" price.
But its up to you. If I had that cost structure (and a air cooled data center) I would not worry as much about ROIs anymore lol
Really? Are there really people paying that much?
