The core features of Bitcoin include decentralization, a limited total supply, transaction transparency, and no intermediary fees. It does not have a fixed issuer; instead, it is generated through the computation of network nodes, allowing anyone globally to participate in mining, buying, selling, and using Bitcoin, with transaction records being publicly transparent. The total supply of Bitcoin is permanently capped at 21 million, with new Bitcoins produced through the mining process, which ensures the security and anonymity of transactions.

Bitcoin's application scenarios are wide-ranging, including global payments and cross-border transfers, decentralized finance (DeFi), and digital asset investments. Due to its low cost and borderless nature, Bitcoin is widely used in cross-border trade, payments, and remittances. Additionally, Bitcoin is viewed as an inflation-resistant digital asset, with many investors considering it a safe-haven asset.
