Stocks that are declared dead and having no assets with no corporate structure continue to trade on the exchanges all the time.
Often they are speculated to have value as a shell company for other companies looking to become traded entities. UPZS was one such case in the beginning. I don't remember the exact number but I think they purchased it for around $350K.
So having lots of shares of a shell can be lucrative. Imagine buying these at .0001 or .0002 and then have it move to .01 or .02
Heck a .0001 to .0002 doubles your money. I have done that twice with apparently dead stocks. I was amazed I could. It is the difference between trading a stock and investing in a stock.
Trading in the pinks is MUCH more lucrative. As I have said to this board MANY times.
