But you do realize you are supporting an ALTcoin that in a few months will be unsustainable.

It is what I like to call FOTM coin.

Edited for clarity.

For those who may have missed it.
I have added Antminer solution into the hardware vs network performance comparison sheet.

https://docs.google.com/spreadsheet/ccc?key=0AmeuPljmUNHCdEpqX2RmMDFwemJyLURVUWFtZ3J3aGc&usp=drive_web#gid=13 <-- speculative return if network increases at 30% each retarget. Ignore anything past 2-3 months. Average network increase to date is just over 20%

Hardware cost is not factored in as most have already paid off their hardware with previously mined BTC.

Edit: After considering the recent news with retailers accepting BTC as payment, and larger groups arrogantly attempting to hold a % of the mining income. BTC is seriously undervalued.

You could go as far as saying that $800 today is $8 Last 2012.

Here is the expected BTC return for a variety of hardware during this present difficulty.


Edit: Reminds me of the similar returns when GPU's were king.

Any hardware up for sell on the internet without putting the effort of getting https:// is a huge red flag....

I updated the Hardware vs Network Speed return document for those who asked.

That is a probable perspective.

However I can see those 170 being put back up from incomplete orders.

If you must then a good motive would be to pay down mining operation expenses/loans.

There was a drop in value in btc due to news from china. During the drop and subsequent rise. A slightly inebriated community member made the typo.

Some found that error humorous and helped release some of the stress due to the volatility.

In hindsight holding durring the volatility has been the safe bet.

I read it as they got back 1/3 of the promissed 1/7.

Congrats

A large % of the spikes can be attributed to variance.
Next target increase is estimated at 30%.

It can take a few hour's to clear up incomplete orders. I give it a day or two and then all unpaid orders will be canceled. This will free up systems for order.

This may be the last batch untill they start shipping.

Actually the checkout process can tie up unpaid orders.
This will free up canceled or incomplete orders.

At this time 170 are still available.

What many forget is that anyone can take a share of the pie.

Running 1 system vs running 10 systems only effect the proportional % of the subsidy pie you get.

Here is a shared document that can help illustrate this fact.

You can increase the amount of power and speed for the given device to see how adding more hardware scales.

Simply create a copy using google docs gmail services.
I recommend you use Chrome browser.

Asic hardware for scrypt is expected to become available some time this year.

Because of this investing in new gpu based hardware has become as risky.

They have been selling close to 25 units a day.
Now they are no longer available 225 to 0.

+1

I would also like to know.

Back when Bitfury and KNCMiner ship the first batch of units, many had reservations concerning possible return on investment.

The reality that btc would rise over its previous ATH had been discussed. However no one not even I predicted that BTC would be trading at over $1000 USD a few month's later.

Other ways to secure btc are available.

Mining is a high risk venture. It can be rewarding in many ways.

I have been providing a mining comparison spreadsheet to help new adopters become familiarized with the aspects of what network difficulty can do on projected returns.

Awareness of past hardware performance help people understand how speculative predicting future network speeds can be.

Here is a link. Create a copy and key in your own values if you wish.

Some great suggestions have been given.
However from what you say your friend seems disinterested in reading and watching videos about the topic.

Perhaps giving her access to her own hardware will help motivate her adoption into this area.
