What are cryptocurrencies?
A cryptocurrency is a digital coin, designed to be transferred between people in virtual transactions. Cryptocurrencies exist only as data and not as physical objects; you cannot actually hold a Bitcoin in your hand or keep Ethereum in your safe.
Decentralized cryptocurrency is produced by the entire cryptocurrency system collectively, at a rate which is defined when the system is created and which is publicly known. In centralized banking and economic systems such as the Federal Reserve System, corporate boards or governments control the supply of currency by printing units of fiat money or demanding additions to digital banking ledgers.
“Owning a Bitcoin means you have the collective agreement of each and every computer on the Bitcoin network that it is currently owned by you and – more importantly – that it was legitimately created by a miner.”
A cryptocurrency, crypto currency or crypto is a digital asset designed to work as a medium of exchange wherein individual coin ownership records are stored in a ledger existing in a form of computerized database using strong cryptography to secure transaction records, to control the creation of additional coins, and to verify the transfer of coin ownership. It typically does not exist in physical form (like paper money) and is typically not issued by a central authority. Cryptocurrencies typically use decentralized control as opposed to centralized digital currency and central banking systems When a cryptocurrency is minted or created prior to issuance or issued by a single issuer, it is generally considered centralized. When implemented with decentralized control, each cryptocurrency works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database.
