If you support Litecoin and other scrypt based coins, this is currently the most efficient mining option available. Either way like I said in my original post, the value in these is not just profit or ROI. Many people would rather support Litecoin by mining coins and supporting the network than outright buying them. For many this has NEVER been an option because the only mining equipment out there are 1kw+ loud machines designed for large farms.
This is also not for everyone, if you want a quick profit this is not for you (and mining in general is not for people that can't ride the bear markets). This is about distributing hash power to as many people as possible, and get as many new people as possible to mine and be part of the ecosystem. This means low cost, quiet, not power hungry desktop miners...which is what I have tried to build with this project.
Are you selling all these units at a loss as well to "distribute the hash power to as many people as possible"?
Think about it: you are making a profit selling these unprofitable boxes to people and sell them the concept that they're doing something good for the community?
I don't see them as unprofitable.
Why do you?
no piece of gear does this efficiency not one this is the most efficient item on the market.
So how is it unprofitable?
The L3+ from bitmain loses money unless your power cost is under 10 cents
I am using the op's voltage saving software I get 5 cents a day on an l3+ at 470 mh and 700 watts at 9 cents power
and on this at 9 cents power I get 11 cents a day for 9 cent power
so I spend 209 on an l3+ to earn 5 cents a day plus add for shipping
or spend 200 on this to earn 11 cents a day
add a psu at 100 the L3+ uses almost the whole psu
add a psu at 100 this uses 1/10 of the psu
I used bitcoin wisdom
https://bitcoinwisdom.com/litecoin/calculatorElectricity Price: (USD/kWh) at 9 cents
Hash Rate: (KH/s) at 100000 for this and 470000 for L3+
Hardware Power: (Watts) at 100 for this and 700 for L3+
LTC/USD: at 59.556
Block Reward: (LTC) 25 the number was adjusted from 50
So spend about the same 200 or 209 and the this is efficient and quiet. earns more at 9 cents power up to 13 cent power
plus loses less if you have power at 14 cents or higher
so this makes more money at 9 to 13 cents power
loses less money at 14 cents or more power
at 8 cents or lower power the L3+ is better it makes 22 cents a day
and this unit makes 14 cents.
So if you want quiet gear and you have power at 9 cents to 13 cents it earns more then an L3+
If you have 14 cent power it loses less then an L3+
Should you buy 100 maybe not.
But I will be getting them as they will be good heaters .
