That instantly turned me away. After reading Applied Cryptography when I was 16 the lesson that stuck with me was "don't create your own security system/cryptosystem." It'll have more holes than a block of Swiss cheese.
I don't write the marketing copy but I do write the code.
We haven't invented any cryptosystems. What we've built is on top of SSL, HMAC-SHA256 signed tokens and Bitcoin.
What is interesting and novel about our security is our use of brain wallets. The wallets are all literally client-side only. If a user adds a password then no one but them can get at their wallet. Of course, they are still susceptible to phishing, theft and other forms of social engineering, but those are all well outside of the realms of cryptography.
You should make that a bit clearer in your copy. Having "proprietary" and "secure" so close to each other in a single sentence can drive more saavy users away.
Other than that, what are you doing to increase trust within the bitcoin system? I have a few friends who work on Wall Street (investment bankers, account executives, etc) and they summarize money as this: "Money is an embodiment of trust. Clients transmit funds to me in amounts with 5 zeroes, or with 7 zeroes, but if they don't trust me they won't send me a single cent."
I think the focus on making bitcoin easy to use with a simpler interface is a side-step.
