I have been invested around one year. Substantial

I have been invested around one year. Substantially fewer shares. 250,000. Curious why you would sell after 4 years. I can afford to lose all I have invested but 4 mil shares is quite hefty. I’d be curious, your insight on this company. Seems like quantum can’t figure out how to monetize their product. Anyway, I certainly hope they succeed. I will hold onto too my shares until there worth much more or the company goes bust. Either way, it’s fun thinking about the company’s potential. Just need too turn some potential into steak.
