Building a Bitcoin miner from Ebay Scrap, with possible option of litecoin conversion

08 May

SEO

I’m planning to do an article on how to convert Ebay scrap FPGA into bitcoin miners.

Target cost is going to be about $100USD per 200MH/s (cost mostly on the ebay scrap)
so in the case of this…

4 FPA rig..

It would only cost you $400usd!!!!!

Now obviously it is not going to have the same ‘expert’ polish as this top of the line product.. but what do you want for 400 bucks..

Yep I know ASICS are coming soon and that Avalon is already on the market.
This is not a ‘get-rich’ quick scheme
Rather it is a last ditch attempt for people to have a final dabble in bitcoin, before the shit hits the fan and mining becomes impossible for most ‘normal’ people.
Who knows this shit may even sell for $250,000USD in 30 years just like the Apple 1

Litecoin… well lets see what is possible….., but from early experiments it is not cost effective even at $100Us because the KH/s rate is way too low

So if anyone is interested post a comment, maybe even check out the advertisers.

The coins?
Well everyone else does it so I can too…….
