Iran is taking crypto out of the speculative realm and embedding it directly into state - level geopolitical infrastructure.
The strait of hormuz handles nearly a fifth of the world's oil supply. Addition of bitcoin as a mandatory fee or war risk insurance premiums onto global shipping, Is this a declaration of bitcoin as a global currency by the Iranian government?
Since they are going to accept Bitcoin payment for insurance that is official announcement and indirectly they announced it as a global currency. I have shared a thread as well where yahoo published a news about this insurance fees. Iran want to raise $10B from the insurance fee, though the amount is quite big but I hope they could achieved their goal.
The positive thing is, when Iran starts this Bitcoin payment, then all the countries will have to pay through Bitcoin as well. That means more countries have to involved with Bitcoin payment though they don't like it. For example my country doesn't allow using Bitcoin but if Iran force to pay through Bitcoin then my government have to pay it. So my government also would think to legalization of Bitcoin.
