I remember a discussion on that subject several years ago, but the complexity and time involved in setting up such a financing arrangement with shareholders was apparently a major drawback from the company's perspective. I seem to remember Dr. Stoll discussing the concept once, though it might have been in response to an email question he received from Ombow.
Daviddal, If you already have a monster stake in this extremely risky company, why add still more? One can easily find several dozen stocks with better prospects than Cortex. That you've never sold a share is amazing, but it may indicate that you've made the mistake of "falling in love with a stock", which is something investment experts often warn about. My problem was always the opposite - I could never hold a big position in anything for long, and would always take profits as soon as they materialized. I was using a lot of borrowed money though, which encouraged a very nervous/jumpy approach.
Owning CDs is the only way I've found to avoid continual, futile bio stock speculating, since the money is all tied up for years and unavailable.
