A man dubbed the ‘crypto king’ allegedly involved in the torture of an Italian Bitcoin millionaire in a lavish New York City townhouse was reputed for spending $100,000 in a single night at an upscale erotic nightclub.

John Woeltz, 37, alongside his supposed partner in crime, William Duplessie, 33, began visiting The Box — a well-known hotspot on the Lower East Side — last February, as sources revealed to TMZ.

The duo, often seen there for consecutive nights, reportedly splurged heavily, spending amounts ranging from $80,000 to $100,000 each visit, according to those familiar with their outings.

On at least one occasion, Duplessie was photographed partying shirtless at the nightclub with a woman perched up on his shoulders.

The duo would often invite girls from The Box back to a swanky SoHo pad for afterparties, the sources said.

The wild details emerged after Woeltz and Duplessie were nabbed for allegedly kidnapping and torturing wealthy trader Michael Valentino Teofrasto Carturan at a ritzy townhouse on Prince Street.

Carturan, who is reportedly worth $30 million, was allegedly lured to the SoHo pad and held captive while his tormentors tortured him for his Bitcoin password.

The sick saga only came to light after the Italian national managed to escape, bloodied and barefoot, last Friday when his captors were distracted, cops said.

He alleged he’d been severely beaten, drugged, shocked with electrical wires and threatened with death for nearly three weeks.

Shortly after his escape, Woeltz was taken into custody and charged in the alleged kidnapping scheme.

Duplessie, meanwhile, surrendered to police on Tuesday after sources said he enjoyed a posh Memorial Day weekend in the Hamptons.
