I'm thinking of something like, feel free to work on top of that, I haven't really put a lot of effort into it:
Here's bitcoin. It's open source money.
Like other successful open source projects, for example Linux, it's impossible for anyone to take control of it. Banks, the government, Evil Overlords, they have to accept that people use it just the way it works best for them.
Paying with bitcoins is easy. In the blink of an eye you'll be able to send them to anyone anywhere on the planet, no credit card, bank, postal service required. It's just as simple as sending email.
Counterfeiting bitcoins is impossible. Each and every bitcoin is scrutinized not only by you or a bank, but actually by all of the computers on the bitcoin network.
There will never be more than 21 Million bitcoins.
Unlike government issued paper money, noone can ever simply print more and reduce your holdings' value.
That might sound like there's too few of them to be useful, but don't you worry, they can be divided into bitcents and even lower. We won't run out on them.
Take money into your own hands. Use bitcoin.
Thanks for that, this is definitely closer to what we are looking for. We don't want to mention "mining" we feel that the average user dose not need to understand mining, much the same way as the average user of paypal dose not need to understand its mechanisms to use it.
