I do not understand what you have written as it makes no sense. Let me simply for you as you appear very confused by the basic maths.
Originally buy at 50.0 cents AUD 100,000
Sell at 17.5 cents 50% or 100,000 shares - leaving 100,000 shares.
If I had not sold 100,000 shares at 17.5 cents today I can sell at the bid which is 15 cents. or 2.5 cents lower.
So I would have lost a further AUD 2,500 for no reason at all. I have now lost 2,500 on the 50% I did not sell.
Everything else you have written is clearly an opinion and good for you. You appear to have a lot of time on your hands.
If other investors chose to hold you just took at 2.5 cent / 15.0 cent or 16% loss for no reason as you could buy back today / tomorrow / next day. Who knows. Share price based on the long term chart is still trending lower.
