*Why is BTC so popular?*

Once dismissed as a fringe interest of tech evangelists, cryptocurrencies—particularly bitcoin—have skyrocketed to mainstream popularity and trillion dollar valuations. In November 2021, the price of bitcoin surged to more than $60,000 for the first time, though it has since fallen. As of mid-2023, an estimated 17 percent of U.S. adults polled by the Pew Research Center had invested in, traded, or used cryptocurrency.

Different currencies have different appeals, but the popularity of cryptocurrencies largely stems from their decentralized nature: They can be transferred relatively quickly and anonymously, even across borders, without the need for a bank that could block the transaction or charge a fee. Dissidents in authoritarian countries have raised funds in bitcoin to circumvent state controls, including to avoid U.S. sanctions on Russia.
