"Oh and - downvoted for sharing of false facts."
That was your stated reason for downvoting my comment in the cited thread.
I write about the markets and market cap is incontestably a representation of value to both traders and investors. It's not the only metric by which value is assessed, but it is among the top. And that's not a false fact. The popular site "Coinmarketcap" implies this by its very name.
You're a Witness. I've had numerous discussions with Wtinesses in which disagreements were expressed and varying opinions were shared. Not once was I downvoted by any of them for expressing a different point of view.
I am a top 70s witness who doesn't usually agree with young mr wolf to be honest, but in this case, he is correct, sorry. Just because some didn't down vote you, you got lucky or whatever, he is free to do so.
The Steem Blue Paper describes the blockchain as a protocol that "enables people to earn the currency by using their brain (what can be called “Proof-of-Brain”)."
It's one thing if downvotes represented an expression of different points of view without negating the visibility of a user's "proof of brain." Instead, they are synonymous with a flag that can be employed by those with greater SP influence to blot out varying opinions, even when those disparate viewpoints are expressed in a clear and thoughtful manner and do not fit the description of content that is commonly cited for flags when one clicks on the flag button.
