How do I change my vallet currency back to dollars?

[Golden Eye]

Steam automatically changed my wallet currency to UAH(Ukrainian currency), to the currency of the country where I live in, BUT every earlier transaction was made with dollars, and now due to the difference in prices between USD and UAH I lost nearly 35% of my inventory's value.
If I try to write to Support to ask for change, It doesn't show my country, supposedly because I must be asking to change not only the currency, but the country included.
P.S. Steam policy is weird. Why not allow to buy in any currency, but still use the region's price in eqivalent?

you dont, you use your currency now. market prices are mostly unaffected by this. 35% is unlikely you did something wrong or used outdated tools.

Yeah you can buy stuff cheaper :)

You can't. You have to use your country's currency.

When my wallet was in dollars, I could sell 1 vanguard case fo 9 cents and recieve 7 cents.
In UAH the lowest price is 1,52 UAH, and after selling i will recieve 1,368 UAH that is rounded to 1,36 UAH (currency is always rounded to the lowest value) and aftet converting it to dollars, it will give me 0,0523 dollars, that is rounded to 5 cents. 5/7*100=71,42% is left of my inventory's value. It's not 35%, but pretty close to it.
Exchange rate was taken as 1USD=26UAH.
