The fact that there are billionaires invested in this stock does not prove that TMPS is not a Pump and Dump. It only proves that they think they can flip this thing around and ride it for the thrill.
Again, I'm not quite ready to give TMPS the P&D label just yet, but there have been so many scam companies run by billionaires (e.g. Bernie Madoff) that you can never be sure till you do your full DD. Remember, a pump and dump will do anything to make itself look legit. That's why the use of generalizations such as this one to justify buying high is a very dangerous play.
