1. What Is Bitcoin?

Bitcoin (ticker: BTC) is a decentralized digital currency that runs on a blockchain. It has no central bank and is not controlled by any government. Its supply is hard-capped at 21 million coins by code, which is why it is often called "digital gold."

Think of Bitcoin as gold on the internet: scarce, divisible (the smallest unit is 0.00000001 BTC, or one satoshi), globally transferable, and recorded on a transparent, tamper-resistant ledger.

2. Why Does Bitcoin Have Value?

Scarcity: Fixed supply of 21 million, with a "halving" roughly every four years that slows new issuance.
Decentralization: No bank or government controls it; you own your assets.
Global liquidity: Borderless transfers with no middlemen, trading 24/7.
Institutional adoption: More companies and even nations are adding Bitcoin to their reserves.

3. What Is OKX?

OKX is one of the world's leading crypto exchanges, offering spot trading, futures, savings, and a Web3 wallet.
