I'd have to disagree with this. Bitcoin's long term success does not depend on a single's person's opinion, regardless of how influential that person is. That's the beauty of decentralisation, in my opinion. If anything, this news will only spark short term hype within the market, and when people realise that this really has no tangible benefits, then that hype will die down.
Also, I share the doubts of other users in terms of whether this statement will lead to any positive regulation. To me, it would be very unlikely to see this ever happen.
But I mean, he is absolutely right in saying that bitcoin's not manipulable. And that's the exact reason why people invest in it, long term. It's not subject to the imminent depreciation of fiat currencies, nor is it as cumbersome and inconvenient as other safe haven assets like precious metals. I'm just not sure whether this is actually news worth reporting though, given that it's a statement he made 2 years ago.
