One excess of his is that he often speaks far too loosely. He does the thing Greg Maxwell (and some leaders on all sides) also do where he will state "X" in a way where X is indeed one conceivable way a fact could be described but is nowhere near the phrasing one would reach for first when trying to describe X, plus there are a bunch of unstated caveats that change the scope of applicability, etc.
Like he'll say (fictional example!!), "Something huge is coming next month. You'll never have to trust an exchange again." But it turns out to just be a paper he wrote that he won't even share yet, that won't do anything for the exchange ecosystem for at least a year, and only applies if you use exchanges in a certain narrow way. And maybe it's also patented but he says it'll be free to use for BCH (unless you start to disagree with him on what defines BCH exactly). Eventually the benefit becomes clear, and it is describable as "huge" in some manner for some people, but is not nearly the size and/or scope you expected. Or maybe it is but the implication won't be clear for even longer.
