• A currency by definition is any commodity which has a value and is accepted as a medium of exchange, Bitcoin fits this definition as it has been used for purchases and is accepted for payments by numerous outlets. Fiat is money cause it is generally accepted to be, same thing can apply to Bitcoin
Earlier this year, it was accepted as a financial representation of value in Germany by the country’s Federal Financial Supervisory Authority or BaFin;
[They are defined] as digital representations of a value that has not been issued or guaranteed by any central bank or public body and is not necessarily linked to a currency specified by law and that does not have the legal status of a currency or money, but is accepted as a medium of exchange by natural or legal persons and can be transmitted, stored and traded electronically.”
Imo however, regardless of the legal position of the country, Bitcoin has the qualities of being immutable, tamper-proof, trustless and irreversible, which makes it a suitable medium of exchange.
• A real currency does not have to be regulated, a legal tender needs to be. Bitcoin is not a legal tender. Its decentralization is part of the appeal that attracts people to the technology.
• Bitcoin does not have any institution which regulates it.
