Is there a way to record a good transaction via trust settings?

This is how it works, buyers can say that their account got hacked and that they didn't order anything.
BANG. your £1000 they paid u dissappears because u cannot prove that you delivered said virtual currency.

simple, and it works some of the time.

These charge backs do not always work.
Sometimes (like in my case) the credit card company judges in the seller's favour.

The only problem is that it can take up to 6 months to resolve these charge back claims.

Its, already been sold, but thanks for your concern.

I've already posted (the miner) it guys! :-)

In fact, most ASICs are not cost efficient by the time that they arrive at your door. Such is the bane of the bitcoin rush...

No Butterfly Labs Product is cost efficient now.
If you buy it, you automatically loose money. What you get is a liability or an expensive souvenier:

The second video is good. The first is just funny.

Please make me an offer.

It runs at a max speed of 8GH/s

I am selling it here for a bargain £220:

I've already been offered .7 BTC for this. I've sold another for £250 already :-)

I have a Butterfly Jalapeno for sale. It is rated at % Giga Hashes per second (5 GH/s), but works all the way up to 7.5 GH/s.

It costs more than £60 to import it from the USA and it took 6 months to get it.

I have lowered the price to £225.

Amazing how the value of this device has dwindled so quickly, especially while it was on route to me.
I've seen them being auctioned of on eBay for £300. I can't sell them on eBay though as they blocked my account for trading bitcoins.

I really like the idea of cex.io. Thank you for sharing it.
I'm reading into it now.
