Tons of older, slower Bitcoin mining appliances for sale.



Can these things be used for cryptology or anything?




Might buy one for $20 or so if any hacks to make them useful for something else.

I just bought a house (In sedona az) to flip, and the basement was clogged with hundreds of gpus and backplanes and power supples.   I gave them all to the local high school to play with.

In the winter if they have a fan they make nice space heaters.  LOL.  Just point it to a pool and hope BTC goes to $10,000.

If it is an ASIC miner it might be useless. ASICs are built for one thing only.

There are other crypto currencies that use the same hashing algorithm that they can be used with.

It's a shame, these things go obsolete faster than even PCs.

 



A bunch just heading for the landfills, I guess.




I would pick up one to play with if some interesting hacks for them.

ASIC stands for Application Specific Integrated Circuit.  
Very useful for one thing but not much use elsewhere.

So hardwired strictly for bitcoin hashing.

 





Faster than using a FPGA type device?

Yup.    It's like using a 555 timer instead of a timer routine in a microcontroller like a basic stamp or Arduino.
The micro controllers are more flexible but ICs will be more efficient.

Well shit, there goes my plans to rule the world with cheap hardware.
 



Would be cool if I could turn them into dedicated realtime stock option pricers or something.

There was a member here who claimed he got in early and made some serious $$$.



I still don't understand the whole hashing for bitcoins thing, and who is injection money into the system.

In the beginning, a bitcoin was somewhat equivalent in value to the amount of electricity that was used to determine a given hash that works as a bitcoin.
Once a hash is found, the finder rushes the the bitcoin database to see if he is the first person to find that hash. If he is, he becomes the owner of the bitcoin.

CPUs gave way to GPUs for a better than 10X power advantage per good hash.
GPUs are not giving way to ASICs for close to 100X power advantage per good hash.

When one space is all "hashed" out they can open up a new space that is based on a different hash so more bitcoins can be mined.
The ASICs good for the first space will probably not be so good for the second, third,...

It is the scarcity and difficulty of duplicating that gives the bit coin its value. (a lot like gold).
