I guess your country is Bangladesh or India. In these circumstances the crypto exchange markets will go away into the dark internet. You can to use VPN, TOR or other anonymizers to make a transactions. To be honest, it is difficult to ban the crypto currencies from the technical side. The government of your country don't know how to control this market, and they did a mistake, I think.
Just for the sake of discussion,,,, any country can actually make some moves on total regulation or control, the worst part is a total banned on crypto currency digital transaction, the government financial institution is very much particular on the entry of Bitcoin or crypto digital transaction in the trading market, because of the huge amount involved. But, the good news they will have to face the FACT that crypto is a Decentralized Digital transaction. when ever they were able to counter or implement the total banned on crypto currency transaction with that country, still crypto enthusiast will just go underground.
