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.
