Bitcoin dips below $11,000 after setting another record high.

Bitcoin dipped back under $11,000 on Monday, coming off a record high just shy of $11,800 it hit on Sunday after a surge from less than $1,000 at the start of the year.

The cryptocurrency, which trades 24 hours a day and seven days a week, climbed as high as $11,799.99 on the Luxembourg-based Bitstamp exchange at around 2100 GMT on Sunday.

Analysts said Friday's announcement by the main U.S. derivatives regulator that it would allow CME Group Inc and CBOE Global Markets to list bitcoin futures contracts had turned sentiment positive after a choppy week.

"The price rises are triggered by continued media interest driven by the expectation of futures trading on CME," Charles Hayter, founder of data analysis website Cryptocompare, said.

Sunday's record high for bitcoin came as Venezuelan President Nicolas Maduro announced the launch of the "petro", which he said would be a cryptocurrency backed by oil reserves, to shore up a collapsed economy.

Opposition leaders said the digital currency would need congressional approval and some cast doubt on whether it would ever see the light of day in the midst of turmoil.
