Bitcoin, based on blockchain technology, has built a decentralized trading network that does not rely on any single centralized institution for management and maintenance. This means that no government, bank, or other organization can arbitrarily manipulate the issuance and trading of Bitcoin, ensuring the security and autonomy of assets.

The total supply of Bitcoin is strictly limited to 21 million coins, and this scarcity is similar to that of precious metals like gold. With the development of the global economy and the increase in money supply, Bitcoin's relative scarcity may give it certain properties of value retention and inflation resistance in the long term.
