So for every new technology that can fundamentally change society, there is always a fear factor associated with it and many times a bubble like we see in crypto bubble is essential for its wider adoption. 2 years ago crypto was not mainstream and not sure how many projects were being implemented in 2018, there are many real projects and application being developed and deployed. The whole block chain technology is very early stage.lot of innovation yet to happen.I think during this process, there will be a bubble, crash and recovery and more new things!!!
thanks
