As Hong Kong is going to recognize Bitcoin as legal tender, Hong Kong is taking this step realizing the far-reaching value of Bitcoin.
If you bothered to read the other posts in this topic other than the one written by OP ((even he didn't say that) you would see that Hong Kong has no plans to make Bitcoin as a legal tender and instead just make it easier for people to buy/sell/trade. While that's a positive news, its far from making bitcoin legal tender and I have no idea how you came to that conclusion.
