Bitcoin briefly fell below $2,500 yesterday and again today, hitting its lowest price since the cryptocurrency rebounded last Thursday.

The digital currency saw a sharp increase on Thursday after miners backed a new mechanism designed to solve the cryptocurrency’s scaling issue.

Here is the latest Bitcoin news, prices and live updates (All times BST).

1.50pm: Bitcoin rose to $2,558.54 by 1.50pm after once again falling below $2,500 earlier this morning.

Bitcoin opened at $2,591.22 and today's low has been $2,461.53, according to the latest date from CoinDesk.

11.30am: Bitcoin fell to $2,485.47 just before 10pm last night. This was the lowest price since Thursday.

Last Thursday more than 80 percent of developers backed BIP 91, a bitcoin improvement proposal. Some welcomed the BIP 91 lock-in a victory a "new dawn" for bitcoin.

The move saw miners agreeing to cement the first part of a larger effort to upgrade bitcoin, called Segwit2x.

Alex Sunnarborg, research analyst at CoinDesk, told CNBC: "I believe the market is currently somewhat torn between the optimism around BIP 91 locking in, which could lead to SegWit activating if all goes smoothly, and the fear of the second half of SegWit2x proposal, the 2MB block size hard fork, still being contested.”
