Why GDP is Wrong Concept?

GDP is total monetary valued of products and services which have been produced in particular year inside the country. For example citizens of one country produce so many products for their use like they make foods, clothes, home, or so many infrastructures etc whatever they need for use, but if they can’t sale their products to outside countries, then  foreign currency amount of central bank would be decreased, if foreign currency amount decrease in central bank, then central bank compel to devaluate own money. In that situation, products and services are increased inside country, but their total valued seems lesser by converting to dollar. So GDP valued always can’t show the exactly countries development level. That’s why it is wrong concept to figure out country development level.
