The security of cryptocurrency is based largely on the underlying technology it is built upon – blockchain. Cryptocurrency transactions are recorded and stored on a distributed ledger, making it virtually impossible to manipulate or tamper with. While some cryptocurrencies may be more secure than others, they all benefit from the same level of protection against malicious actors. As long as users practice good security habits, such as keeping private keys safe and not sharing them with anyone, they can minimize the risk of theft or fraud.
