However, I come to believe that to make in here on hive, you need to invest money to buy vote. That is what I have believe now. Because if you don't have enough Hp to delegate to some individuals, you can't earn their vote. Especially from curation trail. This makes this platform totally centralise.
What has made you believe this?
This is literally a reason I get downvotes on my posts cause I attempted to stop such activities. There are some still ongoing and harder to get in the way of, but I believe there's always some solutions, if its not possible to downvote at times, it is possible to never upvote them yourself. The chain will remember who they are.
I really don't think your overview of how things are here are correct, I run a pretty big curation project and we do a lot to curate users based on different criteria that are not how much Hp they have, how much they delegate to us or their KE, etc. So I respectfully beg to differ in that case.
It's just mind bloggling how twisted some people's thoughts are, and they try to justify their own short comings as created by someone else
