$BTC

Bitcoin (BTC) is the original cryptocurrency — part digital gold, part economic revolution, and part rollercoaster. Here’s a quick breakdown that captures the essentials in 2025:

A decentralized digital currency, invented in 2008 by Satoshi Nakamoto.

Runs on blockchain technology, where all transactions are recorded in a transparent, immutable ledger.

No central authority — it’s peer-to-peer, borderless, and resistant to censorship

Proof of Work (PoW): Miners use computing power to secure the network and validate transactions.

Halving Events: Every ~4 years, miner rewards are halved — the last halving was in April 2024, reducing rewards to 3.125 BTC per block. Historically, these trigger bullish cycles.

Supply Cap: Only 21 million BTC will ever exist — over 93% has already been mined.
