With permissionless cryptocurrencies, a node can be operated by anyone, provided they have the necessary technical knowledge, computer hardware and bandwidth. A distributed ledger is a database with no central administrator that is maintained by a network of nodes.

While buying cryptocurrency is a relatively straightforward process, the decision about whether crypto is a good investment for you may require more consideration. Crypto assets require a private key, which proves ownership of cryptocurrencies and is necessary for carrying out transactions. If someone gets your private keys, they can dispense with your cryptocurrencies however they want.
