Not visible on Monero. Not even Chainalysis can trace it if you don't use one of their nodes. And then when FCMP gets implemented after it's testing phase, there isn't anyone seeing anything on that blockchain. Even the IRS can't admittedly trace it. Of course on transparent spy chains like ETH, BSC, Polygon, OP, SOL, etc as you are referring to can be traced. They are fully transparent blockchains that can be spied on and traced, so yeah they can all circle jerk each other as far as these projects go. And not sure how you don't think that Hive is nothing but a circle jerk, because that is all it is, lol.
All in all, proof of stake is all centralized garbage due to these issues. Again, proof of work is and will always be king because of this, all you have to do is turn on a machine and start mining or running a full node. These chains have actual working infrastructure behind it, not just a few nodes and most with admin keys that can change anything they want at any time, which makes those a HUGE risk. Most of these nodes ran by the same people like most of your PoS networks are. I mean BSC is literally ran by Binance. They control most if not all block producing validators, hence centralized shit.
You can agree or not, I could honestly care less what anyone in this industry thinks anymore, it is what it is. I have worked in enough crypto ecosystems developing and building infrastructure at this point that I know what I am talking about.
