$BTC The bullish movement of **Bitcoin (BTC)** is generally due to a combination of factors, such as:

1. **Institutional adoption**: Purchase by large companies or investment funds (such as approved ETFs).

2. **Scarcity and halving**: BTC has a limited supply (21 million) and every 4 years the reward for miners is reduced, which decreases the supply.

3. **Increasing demand**: Greater interest from retail, use as a store of value or hedge against inflation.

4. **Macroeconomic context**: Weakness of the dollar or expansive monetary policies (e.g. low interest rates).

5. **Technological advances**: Improvements in the Lightning network or adoption in payments.

Bullish cycles often follow historical patterns, with peaks after each *halving* (event that reduces the issuance of new BTC). However, they are also volatile and can correct sharply.
