Geopolitical tensions are heating up: Iran has just announced the closure of civilian airspace. Such sudden events have historically been triggers for risk in the crypto market. Whenever geopolitical tensions escalate, investors tend to shift towards safe-haven assets—Bitcoin and Ethereum are often seen as hedging tools. In the short term, this may lead to market volatility, especially with risk assets facing selling pressure. Changes in the Middle East situation directly impact global energy prices and macroeconomic expectations, which in turn affect crypto market sentiment. It is worth paying attention to the market response in the next 24 hours, especially BTC's performance in these black swan events.
