Not really I think we have a long way to go before this so called "bubble" pops. Btw even if it is a bubble and it does pop don't think the value will simply head to zero it will lose a significant chunk but then again will rebound because the new found price will be super low and not have been seen for who knows how long. Take a look at the housing bubble in the USA in 2008 it popped and within a year things were back to normal basically. Everything went to shit for a bit yes but eventually confidence was regained and the markets function as normal. I expect similar things for bitcoin if when the bubble pops
