While it can be said 32 eth ppl are mini whales sure, theres somewhere around 100k wallets weth at least 32 eth. So just by starting off it's far more decentralized.

That isnt even factoring kn they are all randomly are chosen for a block which makes collusion almost impossible. Its 128 random validators per block.And if they do collide their stake is taken away and burned.

Also there will be 64 shards as well.

So it's some ridiculous number higher decentralized than a top 20 witnesses here on Hive.
