To me ,yes bitcoin is a huge huge bubble of all time.Firstly,Bitcoin cant be used to pay wages due to Bitcoin huge and crazy price fall and rise. People will not want to be paid wages in Bitcoin which  can fall 30% in a day.It is very clear that the price of Bitcoin is based on speculation.Bitcoin had already shot up from less than 1k USD in Jan 2017 to almost 20K USD in December.If this is not a huge bubble, I do not know what is.In fact,Bitcoin rise had ticked almost all the box on the bubble checklist.

1) Most bubbles erupt off on new technology aka dot.com boom in 90s. ( Blockchain )

2) Constant media coverage which allow more investors to have FOMO

3) Speculation driving prices beyond fundamental value ( Hard to find what the value of Bitcoin has except of some strings of code)

Like all bubble, Bubbles do POP and everyone should be careful when it pop.Indeed Bitcoin is one of the biggest bubble of all time.
