Bitcoin breaks $50,000 for first time since 2021

Bitcoin spiked above $50,000 Tuesday for the first time in more than two years as investors grow optimistic that US approval of broader trading in the unit will ramp up demand.

The cryptocurrency has enjoyed a strong run in recent months, fuelled by expectations US lawmakers would allow the creation of exchange-traded funds (ETFs) that track the price and let the public invest in crypto without directly purchasing it.
