Hi,

I've taken my botcoin paper wallet printing project as far as I can with my limited funds.
I need support to cover the startup costs to bring my printer to the market.

Please support my crowdfunding campaign

And help make bitfrore a reality.

I'm working toward creating a shippable product so I'd really appreciate any advice.

I'm currently using ~€45 worth of parts so a rough guess at a retail price would be €80-€90 depending on the manufacturing effort.

Speed is the major problem at the moment so I'm going to investigate different microcontrollers/processors.

Are there any other suggestions to make this a more compelling product?

I thought this BIP was accepted along time ago.

Can someone with the necessary permissions unlock the page or update its status.

Its mentioned that the output of block 0 can't be spent as this would allow Satoshi to fork the network.

Can someone clarify what this means.
I don't understand how being able to spend an output can lead to a fork.

Thanks,

Steve.
