lol good luck with that

lol wrong subforum.

and what overclock is there?

Another data point towards the conspiracy theory that KNC spread the crappy sticker 2 and sticker 3 boards with bad cores through Jupiters.  :D

Sure 15 BTC and I'll buy it

16BTC, shipped overnight, insured, escrow ... to Portland OR, USA

From a point of view (provided that you can find 60GH/s @ 6BTC nowadays) a fair price for this h/w would be 24-26BTC. On the other hand this machine will make you 0.5BTC per day, with current difficulty and average luck factor which -as you may be aware of- will pop (once more) rocket high in less than a week.

My guess is that a price of 16-18BTC would be what the OP should be asking for (and have a chance getting it).

looks like close to 50%

i don't get why ppl are pricing these so ridiculously high, when difficulty is about to go from 267m to something like 380m, possibly higher. 

i came up with something around 15BTC myself

Why so high is because a miner in hand is worth a lot more than something on a slow boat from China. Also a private transaction sold to someone in the EU then you also avoid VAT by declaring it as a used computer.  I know genesis block blah blah blah. Have you seen BTC prices? Currently $204 at MtGox.  You will get your 30 BTC back in 60 days. At that point if a BTC is worth $400 then you got yourself a nice ROI. All about risk versus potential reward.  The one thing genesis block can't predict and no one can is where BTC price will be in 60 days. You can only speculate.

Good point. On the other hand, I paid ZERO (0) customs & VAT via USPS for my BFL 60 shipped from the US to EU. It depends on the company.


No you won't! Read that again:NO YOU WON'T GET BACK YOUR 30 BTC IN 60 DAYS!!! That's because 0.5BTC per day is valid ONLY for up until the next difficulty change (which will drop you down to 0.25BTC or worse). Wait for it in less than a week. This is NOT an estimation via genesisblock (which btw I find pretty accurate and rather optimistic). This is via my own personal measurements judging from MY OWN miner's revenue.


As I wrote above you will need MUCH MORE than 60 days to get your BTC back. Plus the miner should be online all this time. Plus power outage etc. Why don't you buy those 30BTC right away with fiat money (or if you have them just keep them) and sell them double price when and IF the price rockets high...


Exactly... You can only speculate (but you can also make a rather good estimation).

Just my 2 Shatoshis (and sorry for bombing the thread - but I had to make those things clear for all those dreamers out there)

In 60 days if BTC is at $400, then you should have held on to that BTC & you wouldn't be out the extra money from electricity, storage, etc.

You say that someone would get 30BTC back in 60 days...   Let's assume I use the date of your post (the 22nd)... and the seller gets the 30BTC offer and miraculously ships that same day (since it's a Friday).  Uh, no clue how fast/slow carriers are there, but I'll be generous and say it takes 2 business days to arrive, arrives at 8am and is set up instantly.  That'd be the 26th.  

You have approx. one week to mine with this @ current difficulty level, netting you about 2.4 bitcoins (assuming no power outages, no downtime, etc).  On the 5th, difficulty changes to ~520m.  You have ~10 days to mine at this 520m rate, netting you 2.6 bitcoins.  We're at 5 now after 20 days.

I'll be generous and say that from this point, difficulty only increases 25% per increment (last five were 32.13, 27.19, 41.45, 46.02, and the upcoming ~34%).  So you have about 11 days on this new level of 650m, getting 2.3 bitcoins.  The next 11 days you get 1.73 and going forward you get 1.3, 1.04, .98, .74, .56, .42, .32, .24.

A little over 14.5 bitcoins after 130 days (then it'd be something like 200 days?  until you got 1 more bitcoin).     ed:  +/- 10% from arithmetic errors.  didn't use online calculator

Doesn't this thing also use a whole lot of electricity?

So the obvious thing to do would be to buy bitcoin, if you think it's going to be $400...

270 is normal operation at nominal clock with a few usual hardware errors and one of the latest firmwares (for example).

What "overclocking" are you talking about?
