Yeah it is all about educating the people about the advantages of Bitcoin and cryptocurrency technology over the current system. But it would also be wise to point out some disadvantages as well and then let them decide if they still want to use it or not. I am all for evangelizing crypto but let us not get carried away into preaching that we have found the light and the rest are still cloaked in darkness.
Also it is funny that you mention that the current banking system is a ponzi of the corporate elite because the mainstream see Bitcoin as one too. Education is the way to go forward and show them who's who and what's what.
