As Turkish president, Erdogan should urge the country's citizens to use their national currency, the lira, more. This is his duty and the lira will indeed be strengthened in this way. But citizens must also consider their own interests. If the government is not running the country efficiently and the lira is subject to high inflation, it is of course better to seek a safe haven for your cryptocurrency savings. People should not pay for the mistakes of their leaders.
The citizens of Turkey don’t have a choice. They SHOULD use their currency to buy something, because inflation in Turkey will cause the prices of commodities, and services to surge. But never save their money in Lira. Erdogan is scamming his own people.
Agreed, maintaining any kind of savings in fiat has always been a bad idea but when the fiat printed by the government in which you reside is going out of control then it makes even less sense to keep any fiat around.
They must use it as soon as they get it so they are not punished by the rampant inflation going around the country, obviously the Government of Turkey then will complain about it but if the government cannot keep their side of the deal, which is to keep their currency stable, then people should not feel obligated to do the same and use whatever they need in order to improve their lives.
