Of coz, just publish address where to send money to.

is this good or bad?

They're already taking pre-orders 

Crypto-currency will be the driving force behind making this a reality that much sooner.........

You forgot the (TM) sign;)

How close does this come to mining private keys?

This is my fear, that I will wake one day and it will all be over as the private keys get mined. I heard that there are some plans to migrate private keys to something more secure. Does anyone have a link for this?

Did I read that right, private keys are quantum computer proof? Party on then

So, as you have the public keys you could try and brute force the private key that corresponds to the public key. However this is impractical as it would take an extremely long time, like, the sun would burn out before you got the right key. But perhaps some magic future technology can do this, you never know. Some of the things we take for granted today were deemed impossible in the past.

The question isn't necessarily how fast it can compute anything, it's how fast it can compute SHA256. By the time this is out, there will be better ASICs that will be faster for mining than this thing.

Amazing speeds
