There is a rather simple answer to this. "No, Bitcoin is not a get rich quick scheme."
Why?
Do you think it was easy and fast for the people who mined Bitcoin all the way back in 2009 or bought it in 2011? Does the 9 years span seem short to you?
No.
Rather, it's a: "Technical people got the advantage (as it has always been in the past) so they got rich. After that, no one really knows." scheme.
