#BTCBreaksATH A cryptocurrency is a digital asset that uses cryptographic encryption to ensure its ownership and secure the integrity of transactions, and control the creation of additional units, that is, to prevent someone from making copies as we would, for example, with a photo. These coins do not exist physically: they are stored in a digital wallet. Cryptocurrencies have various distinguishing features compared to traditional systems: they are not regulated or controlled by any institution and do not require intermediaries in transactions. A decentralized database, blockchain, or shared ledger is used for the control of these transactions.
