After watching the 2019 Bitcoin rap, I suddenly felt a pang of nostalgia for the crypto world that once aimed to overthrow the banks. In 2019, LinkedIn co-founder Reid Hoffman paid for professional rappers to put Hamilton and Satoshi Nakamoto in an epic six-minute battle. One represented traditional banking and the central bank system, the other Bitcoin and decentralization; they argued in the most direct and brutal way about who should control money. What I miss most is the spirit of the Bitcoin community back then. There was a genuine group of people who believed that Bitcoin could change the world, break the banking monopoly, and allow ordinary people to regain control of their wealth. They were willing to invest their own money, write code, make videos, create music, and even use a rap performance to explain to the world why we need Bitcoin. Seven years have passed, Bitcoin has become increasingly successful, Wall Street has entered, ETFs have emerged, institutions have started allocating funds, and the entire industry has become increasingly wealthy. But for some reason, I always feel like something is missing.
