You can't really apply pump and dump to LTBcoin. The value of the coin comes from the fact that that's the only way to buy advertising slots on Let's Talk Bitcoin show. So the value of the coin will correlate with how valuable advertizing on the show is. You can't really pump the coin too much because advertizing has limited value, also you can't really dump the coin all the way to 0 because advertizing does not cost 0 also.

And Adam from "Let's Talk Bitcoin" is kind of the person you might trust, right?

Anyway whatever it is the coin is very profitable at the moment. Maybe it will change with the time once more people "mine" it, so coins are divided between more people. But at the moment the party goes on for "miners".
