@Haejin - I listened to the entire video. At the end,.... you explained about Steem Power and how it works. I knew nothing about it... so thank you for explaining it. I really don't want to be a cero. My upvote would count for nothing.
I went ahead and transferred 0.024 Bitcoin into my Wallet here (Steem). In just a few minutes they automatically converted into Steem Power - 0.024 BTC gave me 105.2 STEEM POWER.
I think that all of us who have cero upvote power.. should invest a tiny little bit and buy STEEM POWER. It is the least we can do, for all the work you do for us.
