Lately, some key game companies have been integrating NFT (Non-fungible token) systems into their games with live services. If it doesn’t ring a bell, an NFT is a unique piece of data stored on a blockchain, much like cryptocurrency. But it can be anything else like a work of art, for example. It sounds great for gamers who want to make a living doing what they love. But it’s also unsafe since decentralized data is unregulated, which runs the risk of losses and theft.
