I see a lot of "I heard from a friend" and "it seems that" arguments in this thread.
Have any of you really studied the tech and potential of IOTA?

IOTA is only project I know of that offers a permissionless feeless (in theory unlimited scalable) platform for IoT.
It is currently in beta, and yes with a coordinator! But this is needed to start up the thing. Step by step things are getting better.

But hey, maybe Bosch, Fuijitsu, VW, DXC, Porsche are totally wrong about their choice to support IOTA foundation.
Looking forward to June 3rd when more about Qubic will be revealed, which is going to offer smart contracts, oracles and outsourced computing.
Ethereum, here we come!
