A student in Indonesia has made a fortune after turning a collection of selfies into non-fungible tokens (NFTs). Sultan Gustaf Al Ghozali, who studies computer science, took nearly 1,000 pictures of himself sitting in front of his computer over a four-year period, before transforming them into NFTs – unique digital items that are bought, sold and stored on a blockchain. The 22-year-old originally priced each one at just 0.00001 ETH ($3 ) but they soon sky-rocketed in value after gaining the attention of high-risk crypto traders, with individual images now selling for more than $10,000. Is NFT worth investing in ?
