Bitcoin and Cryptocurrency: The Story of the Rise, Promise, and Perils of Digital Currency Online

Bitcoin began as a bold idea: a decentralized currency without banks or governments. In this engaging talk, we’ll trace the evolution of that idea—from the origins of money and the mechanics of blockchain to the rise of crypto speculation, meme coins, and celebrity tokens.

Whether you're curious, cautious, or crypto-savvy, this talk offers a clear and thought-provoking look at the digital currency revolution—and what it has (and hasn’t) become.
