Might need to be careful here...
Only 10 or so holders with more than 2m oppies...so assuming it's one of them, their may be either 2, 3, or 4m more to go...if it's more than one seller, then there is no telling how many more to come.
Technically interesting and nice to see the interest...but still a leap of faith at this stage, especially in the options...so what doesn't the market know?
Cheers!
