$BTC You mentioned "#BTC" — that's the common shorthand or hashtag for Bitcoin (BTC), the first and most well-known cryptocurrency.

Here’s a quick refresher about Bitcoin:

Bitcoin (BTC) was created in 2009 by an anonymous person or group known as Satoshi Nakamoto.

It operates on a decentralized peer-to-peer network without a central authority like a bank or government.

Bitcoin uses Proof-of-Work (PoW) to validate transactions and secure the network, relying on miners who solve cryptographic puzzles.

It's often referred to as "digital gold" because many see it as a store of value, especially during times of inflation or economic uncertainty.

As of 2025, Bitcoin remains the largest cryptocurrency by market cap and is increasingly used by institutions and individuals alike.
