What the poster is saying: your 'brand' is making a promise to help people learn, and he's pointing out that you are not doing that. Your response of "how would you like us to do that?" is not reasonable. If you are making a promise you need to have a plan on the "how"
If your client could tell you how to educate them, they wouldn't need you to do that.
I don't mean this to sound as critical as it may come across. I am not a crypto guy so it's not my place to evaluate your offering holistically. It may be valuable and impressive, I can't tell. But just pointing out that your response on this one issue doesn't inspire confidence if I were to judge you solely on this data point.
