It was another tough start to the week for bitcoin, which shed as much as 8.5% of its value Monday, Jan. 22. While the cryptocurrency was still firmly above the $10,000 threshold, it remained solidly off its record near $20,000 set last month.

These are the headlines you can't afford to miss on Monday, Jan. 22.
