After the speech of US President Donald Trump today, in which he announced the imposition of comprehensive tariffs ranging from 10% to 49% on imports from several countries, it is expected that this move will have wide-ranging effects on the global economy, including the cryptocurrency market such as Bitcoin. 

Potential effects on Bitcoin:

1. Increased demand for Bitcoin as a safe haven:

• The trade and economic tensions resulting from these tariffs may lead to increased uncertainty in traditional financial markets.

• This could drive investors to seek alternative assets and 'safe havens' like Bitcoin to preserve the value of their money.

2. Volatility in Bitcoin's price:

• Economic and political instability may lead to sharp fluctuations in Bitcoin's price, as the market reacts to news and new developments.

Current price of Bitcoin:

Currently, Bitcoin is trading at $85,639, with a slight change of 0.00439% compared to the previous close.

Conclusion:

President Trump's announcement of these tariffs may increase instability in financial markets, which could lead to increased interest in Bitcoin as an alternative asset. However, investors should exercise caution and closely monitor developments due to potential volatility in the cryptocurrency market.
