I was an ActM shareholder, but then I cashed out and bought Labcoin instead (don't kill me because of that). I still follow the thread, and I have only one question: 150 satoshis/share div? Isn't this a little bit overvalued?
Perhaps do a little research looking at the potential of the company before deciding if it's for you.
Do you want a short term return or are you happy to wait a couple of months before seeing a larger return?
