What's about iota these days?
There are many articles about data/streamr should be the main competitor compared 2 iota but in fact it isn't, because it's different architecture inside iota- called tangle.
But data shows in a simple way how 2 track something around- that's the only thing. You can say oh well it works.
Is that all? I would say yes and no..
Iota is in the very beginnings like data but take a look through the iota whitepaper and see

I would say iota is not overrated compared 2 data but data could be bit underrated compared 2 iota.
It's even more the psychology behind the sidefact that microsoft is no main cooperator and investor in the iota ecosystem.
