I'm a bit more optimistic. I eventually see banks and governments working with bitcoin not trying to get rid of it.
It is true though that if you wanted to "kill" bitcoin all it would take is for most governments to outlaw or heavily restrict it's usage. Obviously you can't kill it 100% but if businesses aren't accepting it on a large scale than it would never expand and go mainstream, it would remain a niche thing.
That's right. The only way to kill bitcoin is for (lots of) governments to ban it. Why would they bother to "fiddle with the Internet" at their borders (which is a hugely expensive, difficult task) when they can just ban the thing.
But judging from the last 6 months, all governments will do is "attempt to classify" bitcoin rather than ban it. Even the "bitcoin is illegal in Thailand" story was nonsense. Just some government official saying it hadn't been classified yet, so you can't set up a new business around it. There are several bitcoin exchanges operating in Thailand. The Thai government will always have bigger things to worry about than stuff like bitcoin. Like how to stay in power ..........
