Decentralized network: Bitcoin maintains its ledger through globally distributed nodes, without reliance on a single central authority.

Blockchain technology foundation: Transactions are recorded on a public, immutable blockchain, ensuring transparency and verifiability.

#How Does Bitcoin Achieve Decentralization?

The Bitcoin network is operated by thousands of independent nodes, and no single entity can control transaction confirmation or rule changes. The consensus mechanism (proof of work) requires participants to commit computational power, thereby ensuring network neutrality.

#Why Is Bitcoin's Supply Limited?

#Long-Term Holding or Short-Term Trading?

Ask yourself: if the portfolio drops 60%, would you panic sell? If the answer is yes, Bitcoin is not suitable as a core holding.

#How to Safely Hold Bitcoin?

Cold wallets are safer: Hardware wallets or How to create a paper wallet safely store private keys offline, avoiding network attacks.

Diversified storage: Do not keep all assets on a single exchange or wallet; diversification reduces single-point failure risk.
