I agree and so does Warren Buffett: “Wide diversification is only required when investors do not understand what they are doing.”
I have a friend who has been investing in crypto long before me. He has made a killing, yet he doesn’t really understand even how blockchain works in terms of its core technology. He also doesn’t understand that BTC has failed in terms of its oringinal purpose, and is now just a clunky storage system of value. Anyone can make money. It takes people with vision the make a new world.
