The thing to ask here is WHO is giving those lectures?

• Crypto traders so succesful that are now spending their time teaching others? Don't think so.
• Crypto traders that went broke? Wouldn't be so adviseable for the students.
• Super skilled blockchain developers that run out of ideas to create new projects? Yeah, sure.
• Super skilled blockchain developers that can't find a job? Yeah, right

Well, I got tired, you can go on from here. Really, who that's succesful in this new world has the time to create a class, contents, and everything else?

Don't get me wrong, I don't want to generalize, but I believe that the ones doing it for the right reasons are gonna be just a few.
