So let me get this straight, In order for someone to be an 'insider', you want them to pony up a minimum of 450 btc. You have nothing worked out as far as rates of return, profitability, etc. and you are apparently a one man operation with an idea and nothing backing you as far as real world assets. What jurisdictions do any legal matters fall into? US, EU, Lithuania, Belize, Panama?

This part is nitpicking but the name of your insurance company sounds like something a high school death metal band would call themselves. Take some of the vast sums you raise from your ipo and hire a marketing consultant and work out something that sounds a bit better.

You're asking for a massive amount of btc from the community, might be better if you set your sights slightly lower and started a bit smaller, work out the bugs, and then issue more shares.
