There are several reasons for governmental actions against Bitcoin in some countries. I really believe that some governments around the world fear losing their monopoly on currency and that they will be unable to oversee financial transactions as they wish to do. Even in some Western countries, where it is prohibited under their Constitution to place an outright ban on cryptos, governments have tried to implement restrictive policies aimed at dissuading their citizens from dealing with Bitcoin and other cryptocurrencies.
For instance, earlier this year, our government in Italy tried to impose a special tax on bitcoin trading as high as 40% (flat). Under that tax, you had a clear disincentive from investing in cryptocurrencies since you would be taxed twice as much as regular securities trading. Fortunately, the government backtracked from that legislative measure, But the attitude towards cryptocurrencies and Bitcoin is not very positive.
