Conceptual work created by Italian artist Maurizio Cattelan was sold at auction in New York last week

The cryptocurrency entrepreneur Justin Sun has fulfilled a promise he made after spending $6.2m (£4.88m) on an artwork featuring a banana duct-taped to a wall – by eating the fruit.

At one of Hong Kong’s priciest hotels, Sun chomped down on the banana in front of dozens of journalists and influencers after giving a speech hailing the work as “iconic” and drew parallels between conceptual art and cryptocurrency.
