On one hand, I feel that this person is embarrassed and finally admits the future of Bitcoin, and I see this as one of the history that will be recorded how Bitcoin silences its critics. On the other hand, I feel that this person is trying to take back his words about Bitcoin with his own method, although we don't know what he really means by all that, but I hope it is true that he intends to fix it. Actually, we often encounter incidents like this before, and I even remember there was a media that tried to sneer at Bitcoin and in the end they stopped sneering at Bitcoin, or eventually they get involved. From here we learn not to easily assume something is bad without finding out more about it.
