Just a friendly observation here:
Much of your article is a word-for-word copy of the entry that the cheetah robot has pointed out.
The Steemit community takes a very dim view of such copying.
While I found this article very interesting, and appreciate knowing about what is happening, I would strongly encourage you to read and think about your source material, and then report what you've learned entirely in your own words.
It is OK to quote short sections of other articles, but you need to be clear about it by putting the quoted material in quotation marks, not simply making a general reference at the bottom of your article.
I hope this is helpful, and I wish you well with any upcoming articles! :)
Thanks this is very helpful. As you correctly pointed out - I quoted at the bottom line and I thought this would fulfil the requirements of a good quotation. However, I will consider what you said. Thanks for your thoughts on it.
You're welcome. Steem on! ;)
