I will start thinking Bitcoin is dead when I need to exchange my Bitcoins to other altcoin when I using (spending) my Bitcoins. Not happening today. All I see some altcoin prices up (some > 10x in few months), yet their real useability is almost the same - clear sign of speculation bubble to me.
Yes I do this also if bitcoin dead I will exchange my bitcoin in to the other altcoin because I know when bitcoins deads theres a new coin that will become #1 like the bitcoin. But as of now bitcoin price not dead or not going dead bitcoin as of now have stable price and increasing everyday and every month.
Bitcoin is not dead because it is skyrocketing now.. I actually don't understand why this thread is still open when there's no relevance on the actual standing of bitcoin in the market, maybe the owner of this thread is already dead(inactive) but I was wrong since when I check his profile he was active today.
