Bitcoin jumps 15%, lifting cryptocurrency market value by $20 billion

After weeks of struggling to reach the $4,000 mark Bitcoin finally managed to jump double-digit rebound on Wednesday. It has managed to spike as much as 16 percent, reaching as high to $4,341.44, according to Coin Desk data. After a battered-down thanksgiving week, the new upward development was a turnaround for Bitcoin. The world’s largest cryptocurrency had seen a loss of 35 percent over a week, and for the first time in 14 months had fallen below $3,500. Over the weeks it had also seen its worst ever down 80 percent from its all-time high.
