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.[1] 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.”[2] A digital currency issued by a central bank is referred to as a central bank digital currency.(資料來源 )
A virtual currency that can be bought with and sold back is called a convertible currency. A virtual currency can be decentralized, for example bitcoin, a cryptocurrency. Transacting or even holding convertible virtual currency may be illegal in particular jurisdictions and to particular national citizens at particular times and the transactor/recipient/facilitator liable for prosecution by the State.(資料來源 )
