Comparing our POET with weed is like apples with nuts.

in one year weed fell 62%, but since 2 years they are up 60%.
PTK in one year up 30%, since 2 years down 30%.

I can see similarities: both had hypes and are back at reality and far from their ATH.

But the potential I do regard totally different:
To grow weed you just need a farm, the right climate, and water. A license... Israel is just entering the market, it is not rocket science. POET is a lot of science, and much more. No way to copy this technology, and very difficult to find low-cost alternatives. The tec-giants of this world are trying hard - but so far did not find better ways. And so the potential of PTK is "interesting". We could see this last year: This SPike in March should give us an idea. 250% within one month - just due to the cooperation with Accelink? I guess this year we will see more of this kind of news...
