is there any other hard proof that these all above mentioned countries are actually implementing?
There is no hard proof to say at this moment, but it is a good initiative that a general body is taking up the matter and implementing things to regulate the market rather than some governments who does not have the capability to think on how to regulate the market rather than shutting down the entire market space and making it hard for investors. Lets see how these will be implemented and whether all these said countries abide by the solution set by the task force.
This could be a great news for many countries if that happen and for the world as well because their would be officially many country citizens would start accepting the crypto currencies officially for the merchant payment as well.
