The recent increase in the price of $BTC Bitcoin, which has surpassed $100,000, is due to several key factors:

1. Favorable policies of the new U.S. administration: The election of Donald Trump as president has generated expectations of a more favorable regulatory environment for cryptocurrencies. Trump has proposed to turn the United States into the "cryptocurrency capital of the planet" and to accumulate a national reserve of Bitcoin. Additionally, he has nominated Paul Atkins, known for his pro-crypto stance, to lead the Securities and Exchange Commission (SEC), which could facilitate greater institutional adoption of Bitcoin.

2. Approval of spot Bitcoin ETFs: The approval of spot exchange-traded funds (ETFs) for Bitcoin has allowed for greater participation from institutional investors, increasing demand and thus the price of Bitcoin.

3. "Halving" events: The recent Bitcoin "halving" has reduced the reward for mined blocks, decreasing the supply of new coins and creating upward pressure on the price due to scarcity.

4. Institutional and corporate adoption: Large tech companies and investment funds are accumulating Bitcoin as part of their financial strategies, which has increased demand and contributed to the rise in its value.
