Last week El Salvador unveiled its plan to create a "Bitcoin City". The city will be constructed near the Conchagua volcano, and use the geothermal energy from the volcano to mine Bitcoin. The city will have residential and commercial areas, services, entertainment, restaurants, and an airport. El Salvador also announced its plan to raise $1 billion via a "Bitcoin Bond". Half of the funds will be used to buy Bitcoin, while the other half will be used to fund energy and Bitcoin mining infrastructure.
