Title says it all.

Now that a BFL FPGA single only breaks even with electiricty costs (depending on your rate, in CA it's negative now), what are people doing with their old BFL singles?

Each single generates roughly 0.002 BTC today, hardly worth it to keep the things on.

According to NIST and ECRYPT II, the cryptographic algorithms used in Bitcoin are expected to be strong until at least 2030. (After that, it will not be too difficult to transition to different algorithms.)

Sacrifice it in a ritual of burning to appease the hashing gods!

 Still have mine humming along after I retired my GPU rigs. I'll probably set fire to it this winter by throwing it into a friends chiminea and recording the sights and sounds of its destruction...

I will buy some at $35 each with power supply right now.

I have one left, which I recently turned off. Maybe I will take it to the backyard and have an Office Space Bat Printer moment with it.

It's an FPGA - it'll have other uses.

I'd hang on to it. Someone will eventually port my Litecoin miner to it, the tricky bit will be dealing with the MCU (perhaps Luke-Jr could help out?).

Thank you for your work for the community but please don't give people false hope.  With the scrypt speeds you are getting out of that we are talking so slow that you should still mine BTC with it.  The point is we are talking about less then $5 a month after power (after the difficulty change this week).

I'd be more than happy to take an FPGA or two off someone's hands. I'm always looking for more types of hardware to test with the software bits I write for crypto-coins. See my sig for links.

I agree totally. Its still a factor of three more profitable to mine bitcoin than litecoin using the current Icarus/Lancelot bitstream, as discussed just yesterday on the litecoin forum.

And at just a few cents per day, its really just for novelty value rather than a serious economic proposal. I just didn't like the thought of all those fpga boards going for scrap once bitcoin mining became uneconomic (and the project gave me a chance to brush up on my verilog coding skills  Wink )

Let me say, I do not think they are scrap.  They do have a value, it is just pretty low.  They can be used as an FPGA dev platform.  That is why I say I would buy a few for $30 each.  But I will never get that $30 back mining BTC.

I'd give $50 for one, just to have as a collectable of mining history.

Sell it right now as the price is dropping as we speak Smiley

May be useful for a password cracking setup.

I'm keeping mine as a memento of a past hobby.  I use electric heating so I let it hum away.

Mine it while selling it online at high price, who know you might be lucky. Smiley

I've been looking into that casually. Anything specific you have found that could be interesting?

Hmm, what about throw it away?
Or give it to a friend...

Do the right thing!

Sorry, nothing here. I'd definitely look into it if I had one though. I'm sure there is a decent amount of FPGA password cracking information available.
