Puppet... till now no one feared the chinese government because of selling shares. btcgarden only closed because of the risks involved with chinese crowdfunding, as far as i know. And friedcat always checked out such potential legal risks to Asicminer. I mean it would be pretty stupid to risk all his income. So if you now start to generally question the legality then why not start at bitcoins? Its still a gray area and governments would have any right to forbid bitcoins. That happened with many regional currencies before often too.
So far i trust friedcat more than your legal advice in a anyway legal gray area.
I did not start just now, Ive warned of this when GLBSE opened its doors. Its always been just a matter of time, the laws are completely unambiguous when it comes to trading unregistered securities. At the latest I would have expected people to open their eyes when Pirate was charged for selling unregistered and fraudulent securities.
As for bitcoin itself, I dont see anything clearly illegal about that. There is some faint doubt as to whether or not mining in the US could be considered money transmission and fall under those regulations, but that seems like a stretch to me and no one expects that to be enforced.
Of course once colored coins get used, that may change, if these colored coins represent securities, that has the potential to threaten bitcoin, but the prime risk always has been and always will be issuing and selling of unregistered assets. Thats true for Asicminer just as well, if he is selling to US (EU, Japan, whatever) investors and taking no measures to prevent that, he is breaking US (EU,..) security regulations. Clearly, exchanges will be the target of SEC and similar regulators first, so I dont expect any action against asicminer, but if you ever feel duped, you have a legal slam dunk case.
btw, for the record:
buying unregistered securities is not against the law, in case you wondered.
