Dear @blockshine
Thank you for sharing this link with me. It's kind of hard to comment that video. Nice well created highlight introducing to blockchain technology.
It does amaze me that mentioned network include countries like Colombia or Lithuania or even china and russia (where crypto is "not welcome" by authorities) and at the same time Switzerland is not on the list. That I found surprissing.
ps. welcome back after 1 month absence on Steemit. Unfortunatelly being one month away will affect your post visibility and amount of comments :(
Yours
Piotr
