How MXC came up to that idea?

Iot has a lot of challenges...so I guess this guys just apply blockchain to IoT... because everyone is doing it now, its a trend

Is blockchain living up to the hype?NOO
The reason people followed this stuff is because of the promise that you can get rich for free. That's a very powerful promise
Why the scepticism?
Blockchain is quite slow and energy hungry, making it difficult to scale up. And its distributed, uneditable, anonymous nature seems to create as many problems as it seeks to solve.
The claim is that it is transforming industry. It is not. It's another way to sell new services that vendors are pushing a lot
