As Johnrap says at the start of this thread, they certainly are a tempting play.
With a conversion price of just 5c and with the 'heads' currently trading at 6.9c there is almost zero premium baked in.
I would've thought that with speculation alone of what the share price might be in nearly 5 years, the options would be trading at around 4c or 5c.
Under 3c is a gift IMO.
