Is there anything wrong with it? It's widely known that decentralized exchanges aren't offering the usability and convenience people are looking for, so it's normal that the volumes are very low.
First, the spread is enormous, for 1BTC you end up 1800 down and 1200 up.
Second, yeah the volume is so poor it shows people don't care about decentralization that much.
Third, there is no history of an iranian rial vs btc...so not so much of an alternative.
The problem I have with those so-called decentralized exchanges is that they are not so much decentralized.
1) The owners are holding the funds in an escrow. They can easily lock them up, can't they?
2) In case of a dispute, you have an arbitrage, so again somebody else decides
3) The trade might be decentralized but you still receive your money via banks or other payments methods so again, not so decentralized and this one will never be.
How is this different from LocalBitcoins?
