Even in the land of technology and the place where it seemed like the first place where bitcoins and cryptocurrencies would be widely accepted, then it gets hit with this kind of law. Guess it will still be a long way before we see cryptocurrencies really become mainstream. It looks like it will be just a far away dream in this lifetime.
I believe as long as cryptocurrency exchanges, start-ups and investors does not accept government regulations, it will never become mainstream. The only path to mainstream is to be accepted by governments and every country and for that government requires legalities and must be regulated.
The news I guess is not a big deal, they had found that they are lacking in security so it is wise to withdraw the application and strengthen their security before applying again. It will not only protect the client, it will also protect the image of cryptocurrency, since the concern about hack and hacking incident is really serious.
