LONDON, March 11 (Reuters) - Bitcoin hit a new record high on Monday above $70,400, as the surge in the biggest cryptocurrency showed no signs of slowing down.

It rose to $70,488.50 in early European trading, LSEG data showed. The cryptocurrency has been boosted by a flood of cash into new spot bitcoin exchange-traded funds as well as hopes that the Federal Reserve will soon cut interest rates. (Reporting by Harry Robertson; Editing by Amanda Cooper)
