this is my content, it is just a misunderstanding. I was not sure if post this link or not (to medium), so maybe it was a mistake not to do so.
Sometimes when I want some content to catch more readers I post it to my web blockchainfo.cz and as well to hive and/or to some more sources. About this medium article, we started "Polkadotters" not long ago and as we think Polkadot is a superb project, we felt like sharing this info about this "no 3 of crypto after Bitcoin and Ethereum" to Hive and Project Hope community as well. We might come back to this article a few years later and we will see if it is such a big thing (I think it will be). Like when someone wrote after launching Ethereum a few years ago that it will be a big thing (to maybe put a few dollars into).
Mostly I post my work at the same time to my web and Hive, so it don't grab the attention of cheetahs etc., but this time I did it with a small delay and probably it was not a good idea.
I just added to the end of the article on medium, which you mentioned, a word about sharing the article on hive.blog as well as proof of ownership of this content. Just check the very end of the article there.
