Bitcoin’s climb above $50,000 for the first time on Tuesday marks a psychological milestone for investors—but it could trigger extra regulatory scrutiny. The move higher means the cryptocurrency has more than doubled in value in just two months after several splashy news announcements. The gains come after a 303% increase in Bitcoin’s price last year. In resent trading, Bitcoin was selling for $48.726. Bitcoin was up more than 4% earlier on Tuesday but has retreated back.
