Oil prices ended lower on Tuesday as investors awaited the upcoming OPEC meeting.
Nicolas Maduro and senior government officials, including Attorney General Tarek William Saab, have alleged that the US is orchestrating an alleged plan for a "military invasion" of Venezuela from neighbouring Colombia.
Venezuelan president first proposed the cryptocurrency early in December.
International powers accuse Maduro of dismantling democracy by taking over State institutions in the wake of an economic collapse caused by a fall in the price of oil, its main source of revenue.
The results amounted to a crushing blow to the Opposition which had characterised the elections as a referendum on Maduro, after months of deadly street protests earlier this year failed to unseat him.
"The most painful is the humanitarian problem. There are so many people fleeing or suffering," the pontiff told journalists aboard the papal plane on his return trip from a five-day visit to Colombia.
The opposition has refused to recognise the vote, which comes after months of violent protests in Caracas and other cities against the government and its plan to rewrite the constitution to give Maduro more power.
In his speech, Maduro, 54, said that in addition to firing on Venezuela's high court, the helicopter flew over the Justice and Interior Ministeries.
In the latest unrest, public prosecutors said a 23-year-old man died from being shot in the head with a shotgun in overnight protests in northwestern Lara state.
Almelina Carrillo, 47, succumbed to injuries suffered when she was struck in the head by a bottle thrown from a building during the march in Caracas, Venezuela's state ombudsman Tarek Saab said on Twitter.
