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.
VPN / TOR can be used for crypto-to-crypto transactions. But what he'll do in case he want to convert some of his coins to fiat currency? Almost all the major exchanges such as Bitstamp and Kraken have made KYC mandatory now and there is no guarantee that they will not share the user data with the governments. One option is to go for peer to peer transactions using platforms such as Localbitcoins. But even LBC is not 100% safe and the authorities can track your bank transactions.
