Saga1 my freind, let's put things in perspective...
If the WHO approval was the only factor that would cause you to declare GERONIMA, then all the recent partnerships and mergers of MIR are in vain.
You are a business owner, would you risk a lot of good money after bad if you did not see any potential? think about it.
I think you are just frustrated that you had to wait this long and missed some other investment opportunities along the way.
As investorsr, we all have regrets; but most of my regrets have to do with selling too early...
