everyone needs this cryptographic knowledge since everyone's mindset is when investing something, they know they will have an instant income.
I don't think that you understand what word "cryptography" actually means otherwise you woulnd't write this nonsense.
I don't see media reports that you can get rich quickly with Bitcoin. But I see quite the opposite. Very often, the media warns about the dangers of interacting with Bitcoin.
Media writes what brings them the most amout of clicks/views so during bear market they will claim that bitcoin is scam, that has nothing behind it and that ti will soon go to zero and during bull they will publish those stupid "if you invested $1000 in Bitcoin back in 2011 now you would have xyz millions" types of articles.
