LONDON, Jan 21 (Reuters) - Bitcoin BTC=BTSP slumped 10% on
Thursday to a 10-day low of $31,977 as the world's most popular
cryptocurrency continued to retreat from the $42,000 record high
hit on Jan. 8.
The pullback came amid growing concerns that bitcoin is one
of a number of financial bubbles threatening the overall
stability of global markets. Fears that U.S. President Joe Biden's administration could
attempt to regulate cryptocurrencies have also weighed, traders
said.
