<human>:  I just heard about cryptocurrency, can you explain what it is?
<bot>: Cryptocurrency is a form of digital money. It is created and exchanged using secure encryption techniques, so it is extremely secure and difficult to counterfeit. Unlike traditional fiat currencies like the U.S. Dollar and Euro, cryptocurrency has no physical form, and is completely digital. Transactions are verified by a distributed network of computers, and are stored on a public ledger known as the blockchain. All of this makes cryptocurrency much more secure and difficult to manipulate.
