That is true, but there is actually no need for anyone to be a whale in this system.
People mostly are whales through being around in the early days. A whale is someone who has a lot of wealth, whether it was earned in this system or bought doesn't really make a difference. The more power a few individuals have the greater the risk of an attack vector.
We don't know who some of these whales even are, they could be the same person. There are a lot of whales who never say anything/post/comment/etc.
I have more confidence in this current system than I did with Steem. I would have more confidence in this current system if more people powered up and more whales powered down. Some might argue that we are already decentralized enough but I don't think we are.
This is like saying that the whales (in this system) are not people. This platform is centralized around the whales, which I do not like, because most people are either overlooked or ignored. But the whales are still people. And if more people would power up, that would really increase the confidence of the users in this system. Everyone should power up, but in reality much more people are powering down than up. Most people do not want influence in this system. They want to earn money. And they can do that without powering up their liquid Hive.
I think a good rule to follow is just keep all of the Hive/HP rewards powered up and continue to power them up. If looking to sell something sell the HBD and turn that into Fiat or another crypto.
I run the curation trail for @informationwar and @deepdives we have about 3 million to 4 million HP that upvotes whatever I upvote. I am doing my best to spread that around all of the relevant tags like #politics #truth #conspiracy #deepdives #informationwar and otheres related to it.
By me curating people in those tags I am helping spread around all of that power. The people I upvote are typically decentralized minded people and most of them don't power it down. So there is also that way to do it via earnings and not powering down, we don't need to buy it or have whales sell, but it will be MUCH FASTER to make Hive more decentralized if whales sell and minnows buy.
Decentralization is a constant process that involves a lot of effort, as I said previously, theres no reason anyone has to be a whale on this platform besides them wanting control over the platform. If they were just investors thats different, but we also don't need investors either, what we need is millions of users. We can't really have millions of users unless the whales power down as there isn't enough Hive for millions of active users.
