Surely from a decentralization point of view almost nothing would beat iota.
It is still centralized right? [1] The whole thing is still implemented in ternary [2] for some reason right? Implemented by the people who rolled their own crypto, then when they - days later - were told it was obviously and trivially broken (collisions discovered via differential cryptanalysis) claimed they left it broken as some sort of copy protection mechanism? [3] And then pretended Microsoft was involved? [4]
The one of which Schneier wrote: “In 2017, leaving your crypto algorithm vulnerable to differential cryptanalysis is a rookie mistake. It says that no one of any calibre analyzed their system, and that the odds that their fix makes the system secure is low.”
That IOTA?

You can't transact in bitcoin, and nothing else has any acceptance ... That breaks cryptocurrency, so all one looks at is finding interesting toys.
So I guess I'm doing the same thing as all your posts you linked to, I'm saying "I'm excited, if 'the tangle' demonstrates that it can scale, I'd love to see that happen".
I would suggest nobody invest in any cryptocurrency. That said, having 50$ of play money in iota (and others) is both fun and interesting.
