Virtual currency, or virtual money, is a digital currency that is largely unregulated, issued and usually controlled by its developers, and used and accepted electronically among the members of a specific virtual community.In 2014, the European Banking Authority defined virtual currency as “a digital representation of value that is neither issued by a central bank or a public authority, nor necessarily attached to a fiat currency but is accepted by natural or legal persons as a means of payment and can be transferred, stored or traded electronically.A digital currency issued by a central bank is referred to as a central bank digital currency.(資料來源 )
While virtual video game money is not a new concept, the advent of blockchain technology has created opportunities for crypto gaming developers to add an element of real-world economics to their games. Crypto gamers can earn non-fungible tokens (NFTs) or cryptocurrency by playing and winning a game, and those digital assets then become the property of the gamer. In many cases, in-game digital tokens can be exchanged for stablecoins on either centralized or decentralized cryptocurrency exchanges. These digital assets can be sold or traded on online marketplaces or directly converted to fiat currency.(資料來源 )
