It depends more on the content of the PR than anything else.
Whether they use a stock promoter or not, preferably not, a solid, verifiable PR that completion of a hydrogen generator, a patent application, and/or a marketing plan will send this stock into solid, as in not fractional, pennys from heaven. Which is what this stock is, or soon to be.
Good luck and happy trading to all that have waited this out.
Like the Titan says, trade the stock, don't sleep with it.
