LONDON/SINGAPORE (Reuters) -Bitcoin was heading on Friday for its worst week since February, while dogecoin leapt by a quarter, as the latest tweets on cryptocurrencies from Tesla boss Elon Musk sent the digital coins on a wild ride.

Bitcoin is down about 13% this week, and was last up 1.6% at $50,503. It has slumped over a fifth from its record of just under $65,000 hit last month.
