IIRC mining in Iran on decline due to past blackout which lead to 4 months ban[1] and seized some ASIC before it's released[2]. While i don't know current condition in Iran, it would scare off some miner.
Kazakhstan : 0.07 Usd/Kwh - Easy regulation - Stable geopolitic - Weather ok.
At that electricity price, it's not attractive enough for miner. Currently 0.06 Usd/Kwh or lower seen as attractive.

Bitcoin’s Record Low Hashprice Pushes Miners to the Brink
Even the largest miners struggle amid the market slump
The current hashprice makes it a challenging environment in bitcoin mining, especially for those without competitive power costs. A relevant example is the 4.1 EH/s of Antminer S19XPs that Bitmain has hosted at Core Scientific since late last year. The hosting rate was $0.0745/kWh, suggesting a daily hashcost of $39/PHs—that’s just about the current hashprice breakeven point of $40/PH/s.
According to these statistics, mining companies may start having problems with profit with the constantly growing hashrate.
