This is a stickup — of your virtual cash!

Two armed bandits robbed a Crown Heights man of $1,100 in bitcoins on the street last week, police said.

The 28-year-old victim had arranged through a Craigslist ad to meet with a man who purportedly wanted to buy his online currency May 27, sources said.

After the pair met up at Troy Avenue and Crown Street, the supposed would-be buyer asked the victim to come to his car, a silver Honda, to seal the deal, sources said.

But once inside, a second man in the back seat pulled a gun on the victim, demanding that he transfer the bitcoins to the two men.

The creeps also stole the victim’s cell phone before fleeing.

Police said they’re looking for two men — one of whom is believed to be 19 years old — as well as a woman, whose involvement in the mugging is unclear.

In March, two federal agents who were investigating Silk Road — the underground online Web site where users buy drugs and weapons using bitcoins — were busted for pocketing the virtual currency for their own personal use.

Ross Ulbricht, the founder of Silk Road, was sentenced to life in prison last week after he was found guilty of running the black-market site.

His business, which he ran under the name Dread Pirate Roberts, generated about $1.2 billion, the FBI said.
