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.
Also, Bitcoin does not protect the value of dust currency, it protects the value of your money. If you buy Bitcoin, that's your definition of money and it is resistant to inflation, it does not help stop inflation in fiat.

Those who understand Bitcoin, including its volatility and choose to invest in Bitcoin, are very easy to panic about the price, even though Bitcoin has been proven to be a future investment choice.

Anyone with understanding of Bitcoin and how volatility works would not panic when the price drops. Those who lack the knowledge of the basics and are only into it for a quick profit would.
