Bitcoin is more or less flat against the dollar on Friday as the cryptocurrency’s week-long rally pauses.

Bitcoin charged past $4,400 a coin on Thursday, setting a new record high in the process. Bitcoin dipped in early trade on Friday as much as 2% but, at close to 11.00 a.m. BST (6.00 a.m. ET), Bitcoin is up 0.43% to $4,305.42.

Bitcoin has rallied over the last week. The digital currency broke through $4,000 a coin for the first time ever on Sunday and has since added a further $400 to its peak, although the rise has not been in a straight line. Bitcoin has rallied over 300% since the start of 2017.

Elsewhere, Bitcoin Cash is seeing huge gains against the dollar. The cryptocurrency, which was split off from Bitcoin at the start of the month, is up 12.05% to $499.26 at the time of writing.

Ethereum, the second biggest cryptocurrency by market value after Bitcoin, is up 6.45% against the dollar to $320.45.
