I ran some figures with this calculator.
https://bitcoinwisdom.com/litecoin/calculatorFor the inputs, I have
5% difficulty increment
Electricity price 0
Pool Fee 0
Hash Rate 100 MH/s
Hardware Price 1599
Hardware Power 0
Start Date 1
Deliver Cost 0
Setup Cost 0
Maintain Cost $240 (100 x $0.08 x 30)
Doesn't look good at all.
About 1.5 months before you start paying more on maintenance cost.
I am aware that in a datacentre there is greater scalability so it is probably still cheaper for them to run it on their economies of scale. But, it still doesn't solve the ROI problem. For a start, the pricing should reflect scaling cost cutting benefits as you increase hash rate.
If you buy more you should save more right?
Virtualisation of things is actually a massive cost cutter and any one who runs a datacentre should know that, but these prices don't seem to cut much cost if any at all.
The problem with miners (and i'm none the wiser) is that we all want an idea of a fixed income and we think that mining will give us that. With a bull market there is a fairly even chance of ROI and thats assuming the price of LTC soars back to near previous heights. Right now, if you buy a hashlet you are chasing your money back for the next few months (if you ever get there) and you lose out on market swings.
Imagine if you bought 1599 USD of LTC instead of 100 MH/s of Hashlet.
You can at any point sell any portion or all of your LTC, you can day trade on market swings, and you have the security of having the coins now.
The mindset of mining this same amount worth of LTC and then some more is having it all trickle in slowly, and in a bear market meaning almost making a loss.
I don't agree that Hashlets or GAW are a scam. They are proven to deliver their products. They have excellent history even beyond the crypto mining business.
But lets face it, the hedge is this: GAW know that most people will be optimistic about miners because they are profitable (just about) on today's difficulty and price. (some aren't even that..) The calculations will be way off, and most people will be left with something completely useless and maybe just about ROI or far from it. If today, LTC was soaring to near its previous high and even higher, then yeah, mining would be reasonable. Right now though, i don't see how any one justifies mining.
