Funny thing is that the same analysts who are completely against blockchain will slowly but surely come around and start pouring in money. That will create a bubble. In fact the increasing interest in altcoins and ICOs is creating a bubble which may correct in the short term but it will rebound after that (remember dot com bubble and how the tech companies eventually rule the world now) and there is no way that blockchain can be stopped in the long run - either the technology or the price of the best coins
