Thanks Franklin. I agree completely....they are here to stay.
As for the bubble, I dont think it is in one. Yes the price of many coins has accelerated. However, considering the technological impact AND the fact these technologies are just starting to be implemented shows there is a long way to go.
The blockchain, in general, might see a growth rate that would get any CEO drooling. That will get the value of these systems increasing at a substantial pace.
