I don’t know your age and how old you are but I promise you crypto as come to stay.
The earlier you start understanding it the better for you.
Friends that warned me to learn about crypto in 2017, are now millionaires or near millionaire. I wish I had listened.
Your post is laden with ignorance and I wish you don’t regret it.
This was what the legendary Paul Krugman ignorantly said about the internet in its early days:
Paul Krugman.(A winner of the Nobel Prize in Economics )Paul Krugman wrote in 1998, “The growth of the Internet will slow drastically, as the flaw in ‘Metcalfe’s law’—which states that the number of potential connections in a network is proportional to the square of the number of participants—becomes apparent: most people have nothing to say to each other! By 2005 or so, it will become clear that the Internet’s impact on the economy has been no greater than the fax machine’s.” -https://www.laphamsquarterly.org/revolutions/miscellany/paul-krugmans-poor-prediction
