If I were trapped with expensive shares, I'd do my best to convince myself that DP was credible. But the simple fact still remains - TRTC has fulfilled very few (if any) of the promises made to shareholders over the past few years.
I have reviewed DP's interviews and have found them most credible.
Totally credible - as long as we ignore the fact that none of the developments touted by TRTC have actually come to fruition. But yeah, other than that - totally credible.
