Right now the blockchain space is in a clear bubble. A lot of people (many uninformed) see the price rise and don't want to miss out. This drives the price higher.
At some point there will be a correction. Nobody knows the timing or size. My guess would be that this will not happen until we see the failure of a major blockchain.
With that said blockchains are a remarkably powerful new tool and if they can be sensibly scaled they will be extremely impactful. Blockchains allow for the creation of self sustaining, trustless, autonomous marketplaces. A lot of intermediaries are about to be automated away by these protocols (think about platforms like Airbnb or Uber).
Some useful parallels can be drawn with the dot com bubble. A lot of valuations were totally unjustified, but you would have done very well if you bought and held Amazon stock in 1997 (66,600%).
A more interesting question is whether Bitcoin is the Amazon or MySpace of the blockchain revolution.
