The Securities and Exchange Commission’s recent approval of spot bitcoin exchange-traded funds means that for the first time, people can invest in funds that include bitcoin with no crypto wallet required. Demand for the original cryptocurrency is only expected to grow, and bitcoin mining operators are in position to satisfy it. Two years ago, Marketplace’s Lily Jamali visited one in upstate New York. Stacks of computers burned through tons of power to generate new bitcoins, she reported. Texas is now a preferred hub, and Ben Hertz-Shargel of the consultancy Wood Mackenzie says the SEC’s move will be felt there.
