Nacdaq exchange also known as National Association of Cryptocurrencies Dealers Automated Quotation. It is a centralized exchange founded in 2018. I don't think this exchange provides services to every country worldwide because I tried to access the exchange but I kept receiving a message that indicated that my country was restricted from accessing the services provided by the exchange.
I checked on the Telegram group but I noticed that the exchange had been inactive for a long time without any message from the admin not the owner of the group, I don't advise trading on this exchange in order to prevent loss of funds. The copyright was last updated in 2019 which clearly shows it inactivity and unfunctional.
