I was half joking, but only half.  Three dollars is not very much money in my world, hell you can't even get a cup of coffee in most cafes around here.  In some places, however $3 is half a day's wages, so it may have been an significant fee to the OP.  The real concerning thing is the form he filled out.  What kind of personal information did he give away, under the guise of learning about wealth from this seminar.

I've been to many seminars for work related stuff, and I've found most to be an absolute waste of time.  However, the promotors of the seminars now have my (work) email address.  Coincidentally, after these seminars the subsequent onslaught of related and unrelated marketing emails I get goes up 300 to 400 percent.  So, one needs to ask himself, what's the real purpose of these seminars?  Is it to teach people or mine their data?

Those of us who've been around crypto for any length of time understand that nothing really valuable can be learned in a 4-hour seminar.  If the "instructors" at these seminars have any sense, I'm sure they know that too.
