Agreed. If people would stop selling for cheap now and stop continue to depress the share price, the price could rise and they would need to sell less of their shares to cater for their financial needs.

That is why I never invest any money that I might need eventually at some stage. Because I don't want to sell, because I have to and at the wrong price for me.
I want to sell, because I want to, because it is the right price for me.

Its called investing not gambling. 
But everyone to their own. But those people shouldn't complain about a low SP as they are to an extent the reason why it stays so low, as buyers have absolutely no reason to buy from the ASK as the never ending supply serves their purpose to get cheap shares without chasing the SP.

Therefore the SP doesn't start to get chased and therefore won't rise. But who do I tell, I assume everyone knows how the market works.
