Unless major flaw is found, bitcoin will live long. If a major is found, bitcoin will resurrect.
Flaws are found every day and they are patched quite fast... I don't think there are any major flaws in this system
I don't think he means flaws when he mentions 'major flaws'. I assume he means what if the bitcoin security isn't up to the mark and a huge hack takes place or a lot of people become victims of a huge scam. That will surely affect bitcoin, and I don't think bitcoin can bear anymore negative media attention, people will just stop believing in bitcoin then man.
that's not a problem with bitcoin, but with exchange, if they are incompetent nothign we can do to "patch it", also even an hacker right now, would not dump his coin seeing this great surge
