Bitcoin Surges 25% on Hopes of US ETF Approval Attracting Mainstream Investors

Bitcoin has risen 25% in the last month, with most gains during US trading hours, showing US institutions embracing possible Bitcoin ETF approval.

ETFs allow investors to gain exposure to crypto without directly buying digital assets.

Analysts expect Bitcoin ETF approval to attract lots of mainstream money.

There are about 420-440 million crypto owners globally, with 260 million in Asia and 54 million in North America.

Asia has the most owners but US traders and institutions have greater buying power.
