SINGAPORE (Reuters) - Bitcoin fell heavily on Friday and was heading toward its sharpest weekly drop since last March, as worries over its technology and regulation extended a pullback from recent record highs.

The world's most popular cryptocurrency fell more than 5% to an almost three-week low of $28,800 in the Asia session, before steadying around $30,000. It has lost 15% so far this week, the biggest drop since a 33% fall in March.
