The fourth largest bitcoin exchange in terms of trading volume, Bitfinex announced the launch of a decentralized trading platform EOSfinex, which is based on the EOS blockchain.
Great. You're bumping a thread that was last posted 7 years ago and all you up to say is that, which is obviously off topic.
There are some countries where bitcoins are currently sold for $18 000 <Iran> on informal markets, not on exchanges. If you can find someone to sell your bitcoins at that price, you will make a significant profit. I did some work in Zimbabwe a while ago, when the same thing was happening and I tried to sell some bitcoins for a much higher price than what it was on exchanges, but I only managed to make one trade and then thing fell flat. <They pull you in by doing a genuine trade and when you do the next trade, they try to scam you.>
As I said, this is not via exchanges, but rather P2P trades.
I think you're mistaken as this issue was already cleared, bitcoin price is entirely the same anywhere else.
If you really want to convert IRR to USD, you have to use unofficial exchanges, which offer a $1 for 140k IRR rate. If we use that instead, you're only going to end up with ~$6k, which is just about what Bitcoin is normally worth. The whole process will be pointless.
