I'm sure everyone is familiar with that picture of the USD losing value over a century but still that's nothing compared to this.
Imagine a currency that was 1.25% of the USD in 1980 becoming 0.000085% of it.
From a peg of 80 rials to a $ it has come down to 1,150,000 rials for a dollar.
Of course, getting their ass kicked by Israel and the total humiliation didn't help so with inflation of over 35% a year, declining oil and gas production and price the rial is on such a freefall they can't even deal with normal numbers anymore.
As banks collapse right and left, you get news like this:
Iran’s Central Bank revoked Ayandeh Bank’s operating license on Thursday, dissolving one of the country’s largest lenders due to massive losses and chronic inefficiency in another sign of gathering economic storm clouds as sanctions bite. Farzin said that the bank had 5.5 quadrillion rials ($5.1 billion) in accumulated losses, 3.13 quadrillion rials ($2.9 billion) in overdrafts, and a negative 600 percent capital adequacy ratio.
Yes, they are using
quadrillions there!
If you still don't understand the sorrow of the situation, this thing:

Is worth 0.1 cents!

Each sheet in this premium toilet paper is worth 0.3 cents!
Oh yeah, and a Bitcoin is about 110 000 000 000 rials, and the whole market cap of crypto is
4 000 000 000 000 000 000 rials! Those are quintillions, when was the last time you used that number?

What do you mean? This is SUCCESS!!! Iran, with its wise government and stable economy, has the highest real value of all real currencies! Everyone is a millionaire or even a billionaire! Which of the “decaying West” countries has been able to provide such a level of income to its citizens?

)))
Of course, I feel very sorry for the people of Iran, because galloping inflation in a weak and limited economy causes huge problems for people, and this cannot be cured by removing zeros from paper... The saddest thing is that the people of Iran do not deserve such a fate!
I hope the people of Iran will make the right decisions and return the country to prosperity, which they deserve and which was stolen from them by dubious leaders.
