Bitcoin ($BTC ) is the first decentralized cryptocurrency, created in 2009, operating on a blockchain. It is considered "digital gold" due to its scarcity (limit of 21 million units).

**Is it worth investing?** It depends on the profile:

✔️ **Pros**: High appreciation potential, hedge against inflation, growing adoption by institutions.

❌ **Cons**: Extreme volatility, regulatory risks, and technological uncertainties.

**Recommendation**: It can be part of a diversified portfolio (5-15%), but only with capital that you can afford to lose. For conservative investors, it is not ideal. Study and monitor trends before deciding.
