What Are NFTs, Anyway? One Just Sold for $69 Million.

A digital-only artwork has sold at Christie’s auction house for an eye-watering $69m (£50m) – but the winning bidder will not receive a sculpture, painting or even a print.

Instead, they get a unique digital token known as an NFT.

Where Bitcoin was hailed as the digital answer to currency, NFTs are now being touted as the digital answer to collectables.

But there are plenty of sceptics who think it is all a bubble that is going to burst.
