The point is that Trace can write a blog post about bitcoin. It's a rhetorical device rather than something that he expects Michael Pento to pay attention to, and if it does get the attention of Michael Pento and he reconsiders his views on bitcoin, well that's a bonus.
I doubt the post is targeted at Mr. Pento at all but instead those who might listen to and follow his advice. If anything it is tangentially targeted at Mr. Pento as some helpful business advice assuming he wants to retain a shred of creditability and not become irrelevant.
