With a 10c Exercise Price for a 1c share, there would have to be a massive upside, that only few would've been privy to. Obviously not the case.

One must ask why set an Exercise Price of 10c 3 years ago when the share price was closer to 20c ie 50%.

When you look at the option classes currently in play, the May 23's are currently at 1/3, 30% of the current share price, seem reasonable given they have a little less than the 2 years, 20months, to expiry.
The rest are either too expensive, timeframe is too short or both.

Assume, in your wildest dreams a DXN share price of 5c. This would be a 5x, 500% increase.

DXNOD would be around 3c, difference being exercise price of 2c. This would be a 10x, 1000% increase.
Herein lies the benefits...and gamble of options.

Further projection for these current expired August '21 options at this hoped for exercise price of 10c.....

DXN @ 10c means 10x, 1000% on current value.
DXNOD @ 8c means 24x, 2400% on current value.

Three years ago 2018 August 17c per share.
Two years ago 2019 August 5c per share.
One year ago 2020 August 2.5c per share.

May 2018 @ 25c+ DXN looked a good thing and future cheap options were good for the balance sheet. This of course relied on the share price 'performing' to make the options very 'juicy' indeed. Make of this what you will.........just saying....
