EstimaPrediction

Turkey is going through high inflation and nobody can estimatepredict what will happen into Turkey's economy situation.

(1) The word to use here is "predict". "Estimate" is used for more quantifiable things such as numbers, values, or extents. We do not use "estimate" when talking about general situations.
(2) You can use "economy" or "economic situation".

Although the president asks for low interest rate s, the minister of finance is keepsing the interest rate high for a while to curb inflation.

That's why no one can guess how much of inflation can bewill go down andor whether the president will fire the minister or not.

"Or" might be more appropriate than "and" here, as how much inflation will go down and whether the president will fire the minister are two separate questions that can be asked separately.

If he is fired everything will gobecome worste.

TIf that happens, the inflation couldwill not be control for 5 years and if it happend, it could notable to be controlled for next five years.

There seems to be unnecessary repetition in this sentence, so I have deleted parts of it.

Therefore, BYD is waiting for Turkey's action for a while and thenbefore makesing a decision on how to processed.

I tweaked your sentence so that it sounds more fluent.
