Even Malaysia's central bank could introduce rules around cryptocurrencies by the end of this year.
So as on my opinion official crypto currencies of different countries will have bright future.
Introducing rules and coming up with their own cryptocurrencies are totally different. If governments introduce any product then surely it will have a more trust but not sure whether people will go for it. Anyway they haven't provided any details of their new coin so let's wait and see how it is different from bitcoin or it is just copy of bitcoin.
