A tariff wave is causing a stir in the global markets. Recently, Trump announced on social media that a 25% tariff would be imposed on countries conducting trade with Iran. After the announcement, capital markets instantly plunged into panic. Although the specific details have not yet been disclosed, this clearly represents a comprehensive blockade against Iran's economy. From one perspective, this reduces the immediate risk of military conflict, but market sentiment has already reacted in advance.

Crypto investors are no strangers to such news. In October last year, a similar tariff announcement triggered a 15% single-day drop in Bitcoin, with altcoins halving in value, leading to 300,000 liquidations. Why is the impact so severe? The core reason lies in excessive leverage use in the crypto space, especially in the cycle of borrowing involving high-yield stablecoins like USDe. The entire structure is as fragile as a Jenga tower. Once macro risks hit, the chain of liquidations can be far more powerful than market expectations.

However, this time’s situation warrants further consideration. The Iran situation itself is not breaking news; last year's internet shutdown already caused domestic cryptocurrency trading to halt. But from a long-term perspective, Iran’s 5 million crypto users are actually becoming more reliant on stablecoins and Bitcoin as they seek safe havens. Trump’s latest sanctions may further accelerate capital flows from Iran and other sanctioned regions into the crypto market, especially Bitcoin and mainstream stablecoins.

**Short-term risks should not be underestimated**

The market fears uncertainty the most. Before the details of the tariff policy are fully implemented, large investors will inevitably adopt a wait-and-see attitude. This is especially dangerous for altcoins with already low liquidity, significantly increasing the risk of flash crashes. If your portfolio includes high-leverage positions, now is the time to seriously consider reducing your holdings.

**The long-term landscape is changing**

Residents of sanctioned countries worldwide are being forced to accelerate their adoption of cryptocurrencies as a safe-haven asset. Iran’s case is just the tip of the iceberg. In this process, Bitcoin’s role as digital gold will become increasingly prominent. If geopolitical conflicts escalate, gold and Bitcoin may advance together, even forming a new way of asset allocation for risk hedging.

**Practical advice**

First, avoid excessive leverage. The lessons from October last year are still valid; liquidations can happen in an instant. Second, closely monitor Iran’s internet policies and the evolution of sanctions. If the internet blockade is lifted or policies loosen, large inflows of Iranian funds could trigger rebounds in certain small-cap coins. Third, allocate a moderate portion of your portfolio to Bitcoin as a long-term defensive asset. The more chaotic geopolitical tensions become, the stronger Bitcoin’s insurance properties.

Trump’s tariff drama has just begun, and more variables are likely ahead. As an ordinary investor, the current strategy is not to chase prices blindly or panic sell, but to stay calm, prepare sufficient ammunition, and wait for the market to panic truly before bottom-fishing opportunities arise. The long-term prospects for BTC and ETH remain promising.
