Iran has become a hotspot for illegal mining after many miners began to decamp there to take advantage of the country’s heavily subsidized energy (partially due to the fact that Iran can’t sell its oil due to international sanctions). Around 4.5% of the world’s total bitcoin mining now takes place in Iran, making it one of the top 10 bitcoin-producing countries in the world. The crackdown by the government may knock it off the chart, but miners will surely sniff out another cheap source of electricity somewhere else in the world and set up shop there.

“Tehran allows cryptocurrencies mined in Iran to pay for imports of goods, which can help it get around the wide-ranging U.S. sanctions that had been imposed on the country…”
