The birth of Bitcoin, which is known as crypto in the digital era, can be used as a new type of investment in an effort to protect the value of fiat currency which can change or even be worthless.
Bitcoin is a type of cryptocurrency, making crypto an umbrella name for blockchain digital assets, and not a different name for Bitcoin.
