Use VPN. Some users here are experiencing that problem also. So try using vpn to bypass the blocking. If your country prohibits visiting cryptocurrency related site, then cryptocurrency is more like banned in your country. Is cryptocurrency there is banned? Very sad for you. Don't use ordinary VPN because they can easily traced by ISP and you'll end up suffer with the consequences.
Using VPN can solve the problem of being able to use the crypto-related website including this forum, but this cannot solve the problem that he might face in the near future. His earnings might not be able to withdraw due to the circumstances, banks may freeze his account nor able to withdraw it in any kind of service if the country prohibits the use of cryptocurrency.
