I don't believe that anyone can know how long another person has been invested unless they have access to their brokerage accounts.
Years ago, when I asked for people's forecast on the close a year later, I received answers from people who'd been observing the board, and said they've been invested for years, who chose to get in at that time with their predictions.
I believe we still have many investors who follow what's said here, but don't post. At some point some of these people choose to become active posters, it's everyone's choice.
I don't believe that the person who first told me about NWBO ever posts on any board. I have no doubt that he's got a major investment here and has had it for many years.
