Iran’s cryptocurrency market doesn’t operate like anywhere else. While most countries debate whether to ban or embrace crypto, Iran does both-allowing mining while blocking trading. If you’re an Iranian citizen trying to protect your savings from the collapsing rial, you’re caught in a legal maze where the government wants your crypto profits but won’t let you spend them.
Why Iran Blocks Crypto-to-Rial Trading
The Iranian rial has lost over 90% of its value since 2018. Inflation is above 40%, and international sanctions have cut off access to global banking. People turned to crypto not for speculation, but for survival. Bitcoin, USDT, and other stablecoins became digital lifelines-ways to store value when the rial was rapidly turning into paper with no purchasing power. But the Central Bank of Iran (CBI) saw a problem: if people could easily convert crypto back into rials, they’d keep pulling money out of the banking system. That made the rial even weaker. So on December 27, 2024, the CBI shut down all domestic crypto-to-rial payment gateways. No more buying Bitcoin with your salary and then cashing out to pay rent. No more exchanging USDT for rials on local exchanges like Nobitex or DigiKala. The move wasn’t about stopping crypto. It was about controlling it.The $5,000 Stablecoin Cap
The biggest shock came on September 27, 2025-just hours before the UN reinstated sanctions. The CBI announced new limits on stablecoins, the most used crypto asset in Iran. - Individuals can buy no more than $5,000 worth of stablecoins per year. - Total holdings must not exceed $10,000. - You have one month to reduce any balance above $10,000. These rules hit hard. Tether (USDT) is the backbone of Iran’s crypto economy. It’s used to buy groceries, pay doctors, send money abroad, and save for emergencies. A $10,000 cap means a family can’t hold enough to cover even six months of inflation-adjusted expenses. The government didn’t ban USDT. They just made it useless for long-term savings. People who held $50,000 in USDT were forced to sell, convert to DAI on Polygon, or risk having their wallets frozen.Tether’s Freeze and the DAI Migration
On July 2, 2025, Tether froze 42 Iranian-linked addresses. Half of them connected to Nobitex, Iran’s biggest exchange. Others were tied to wallets flagged by Israeli counter-terrorism agencies as linked to the IRGC. The message was clear: if you’re using crypto to bypass sanctions, you’re a target. In response, Iranian users didn’t stop using crypto-they switched. DAI, a decentralized stablecoin on the Polygon network, became the new default. Why? Because DAI doesn’t rely on a single company like Tether. It’s harder to freeze. Polygon is faster and cheaper than Ethereum. And it’s less visible to global regulators. This wasn’t just a technical shift. It was a survival tactic. Iranians learned to adapt faster than most governments could react.
Advertising Ban: No More Crypto Promotions
In February 2025, Iran made history by banning all cryptocurrency advertising-online and offline. No YouTube videos. No billboards. No Instagram posts. Even influencers were told to stop promoting exchanges. The goal? Stop new people from entering the market. The government didn’t want more users. They wanted fewer people chasing crypto as a quick escape from the rial’s collapse. This ban is unique. No other country has gone this far. Even China lets crypto content exist under tight control. Iran wants crypto to disappear from public view.But Mining Is Still Legal-and Profitable
Here’s the twist: Iran is one of the world’s top five Bitcoin miners. It’s not a secret. The government encourages it. Why? Because mining uses cheap electricity and generates hard currency. Iranian miners sell their Bitcoin on international exchanges and send the proceeds overseas-often through third-party intermediaries. That money doesn’t go through the rial system. It stays in dollars, euros, or gold. Iran’s mining industry brings in about $1 billion a year. That’s 4.5% of global Bitcoin mining output. The government doesn’t tax miners. They don’t regulate their wallets. They just take the energy bill and let the profits flow out. It’s a clear signal: crypto is fine if it benefits the state. Not if it helps ordinary people.The Digital Rial: Iran’s Own Crypto
While Iranians scramble to hold USDT or DAI, the government is rolling out its own digital currency: the Rial Currency. It’s not Bitcoin. It’s not decentralized. It’s just an electronic version of the paper rial. - Issued only by the Central Bank. - No mining. No supply limits beyond what the government decides. - Tied 1:1 to the paper rial. A pilot program started on Kish Island, a tax-free zone where tourists and foreign businesses operate. The goal? Replace dollar transactions with digital rials. But here’s the catch: no one trusts it. Why would you hold a digital rial when the paper version is losing value every day? The digital rial isn’t a solution. It’s a control tool.
