Bitcoin Forum

21 BFL singles all revision 3 with the working front led. Sales to continental USA only. Have the kindness to avoid making stupid and or insulting offers, I won't even grace you with some troll food and will lock the thread. I would prefer to sell them as a lot. I have sold 2 to "papaminer" a couple of months back if anyone want a forum reference. I'll post a few pictures later.

You not interested in posting to the UK mate?

My reasoning for not "wanting" to ship international is that the shipping gets very expensive for such a large number of units, there would be around ~$2100+ in VAT on European deliveries I made an approximation of the shipping cost using the fedex calculator and without any insurance/tracking/packaging materials etc.. shipping the singles to london would cost ~$442, since there is no way to prove that the units are "used" european deliveries would charge new singles price in duties ~$100, once it leaves USPS, fedex, or whatever company's hand it's a bitc* to get them to honor the insurance if anything happens. So it's nothing against sending it overseas....I am just trying to make this simple.

Will buy all or half for $400 each + ship.

Since another person here in the forums had much better success using Ebay I decided to post 10 units on Ebay as a sales test. Pictures are included in the Post.

Calculator:http://bitcoinx.com/profit/index.php

Being very generous
With a constant difficulty of 3438908 (unlikely) and a block reward of 50 BTC (highly unlikely), today's current BTC value of 12.12 (anyone's guess), hash rate of 832 (https://en.bitcoin.it/wiki/Mining_hardware_comparison#FPGAs), a power draw of 80 W, a 0.10 $/kWH (probably average but most veteran miners could get slightly better rates) and a cost of $500, it will take

182 days before the unit breaks even. 

But bar an act of god (or the devs), the block reward will halve sometime in the next day or so, so let's adjust our calculation.

Being somewhat generous
With a block reward of 25 BTC and the rest of the above being the same, it will take 1 year and 25 days to break even. 

But this assumes that during that first year, the difficulty won't budge, which I'm sure no one here believes.  Based on pre-order estimates, it's estimated the difficulty will increase any where from 7-40 fold.  Please let's now assume that the difficulty doubles tomorrow and stays that way for the duration of our mining period

Being generous
With a block reward of 25 BTC, and the difficulty at 6877816 the duration of our mining period, it will take 2 years and 187 days to make even a single penny.  Of course this all assumes that your electricity rate stays constant and the unit doesn't break or malfunction.

More realistic
With a constant difficulty of 34389080 (10 fold the current difficulty what I believe to be a reasonable estimate) and a block reward of 25 BTC, today's current BTC value of 12.12, hash rate of 832, a power draw of 80 W, 0.10 $/kWH and a cost of $500, it will take

never.  It's so far into the future it's not even worth calculating.

But wait! The saving grace!  The price of a BTC!!!

Fair enough.  I think throwing darts on a Mt Gox Live chart will have just as much luck as any of our predictions on the price of BTC, but let's use a quick 1,2,5 scale so that roughly x1 is not generous at all, x2 is generous and x5 is quite generous indeed! (Again, back of the envelope calculations and quite possible they are all lowballs). 

Using the "More realistic" scenario with $10 a BTC, obviously the timeframe is still never.

With BTC going for $20 a piece, our pay of period is a shy under 27 years!

Finally, with one shiny Bitcoin selling at 50 Federal Reserve-funded Greenbacks, the payoff period is 3 years and 106 days!

Now here is where I think there is a glimmer of hope.  With a mining period that long, it's entirely feasible that the price of BTC will have risen that high, what with decreased growth rate and probably more adoption.  That being said, there a probably a half dozen other investments offering better mining returns.  Unless the price drops to the $100, I think I will pass.   

Oh come on. Anyone buying used Singles is just using them to upgrade to ASICs. Everyone knows that.

Can you still upgrade them at this point?  I thought there was a cutoff?

Cut off is end of march at this point, was end of Jan but got extended.

Yep. So until the end of March, they should be worth at least $600.

Jaryu, do you still have any Singles for sale?

     I bought one Single from Jaryu and received it in excellent condition and it's been up and running a couple days now.  Took alittle while to get here but overall a positive and successful  transaction.

Just to clarify: there is no import VAT or taxes for Europeans on second hand items person to person from anywhere!

Sent you a PM.

Bought another 4 Singles from Jaryu on 12/18/12 and paid via Paypal.  Hope to have them as an early Christmas present for myself   ;D  Will post again after I receive them.  Thanks Jaryu

To clear things up for you Americans:

Shipping used items to EU or UK from the US: Buyer won't be charged VAT.

FYI..  i bought 3 of the ones he had on ebay and received them in excellent condition and they are working great.

As a matter of fact, i am sending him a pm to see if i can buy some more...
