I was thinking Mark wanted more like $10-15 million.
But whenever I calculate my dream value I assume we will eventually have 100 million shares @ $2 billion market cap = $20, which equals $1 million for myself. Even if it takes 10-15 years my rate of return will be very good from a cost basis of ~$0.40.
I never thought about owning it for 10-20 years but, if this procedure is as good as we think, that is an interesting option. At $20 I would only have $500,000 because I sold some. All my shares are in an IRA now so I guess I could wait. It would be worth it.
