First of all, cryptocurrencies =/= blockchain, or blockchain =/= Bitcoin. There are countries where blockchain is much appreciated even if Bitcoin is not. Even a good number of banks are appreciating the blockchain technology, even using them, but they are not in favor of the likes of Bitcoin and other cryptocurrencies. In my local setting, a few banks are already playing with blockchain but a mere mention of Bitcoin or cryptocurrency when opening an account could be enough for your application to get rejected.
The real issue is though, does your control support decentralization? Almost every country in the world supports blockchain technology, but a lot of them don't like the decentralized aspects of it (for example BTC), I want countries to allow us to have more freedom with our money.
