I did not say AirBnB and Uber "got killed" by regulators. I said that it had, at one point, reached a level that was clearly beyond what was within legal limits, and that afterwards "large parts" of that got shut down. BTW: This is a trend that is still ongoing and we have by no means reached the end of it, especially in Europe where there is a lot more regulation around who gets to be a taxi or a hotel (see Madrid taxi strike raising awareness about Uber's illegal role in the market there) The SEC ruling that bitcoin is not a security is not really saying anything much as there are many facets to it (should the law treat it as being somehow equivalent to cash? equivalent to transactions carried out by banks?). It's also not saying anything about this pesky little thing that Americans keep forgetting about called "the rest of the world" and even if bitcoin is not in voilation of any laws that exist now, that doesn't mean that new laws won't be brought in to outlaw bitcoin etc. etc.
