Nice article bro.

  I'm not an expert when it comes to this topic so I can't really write about it. I simply hope these developers of Steemit know what they're doing and only want the best for the platform. Generally, I suppose they are good and intelligent people. I only know sth. regarding the Voting Power and Bandwidth has changed - now it's called Mana and Resource Credits or sth. like that. And I've heard about some other things too but I ain't too much into all of that. I have learned something about it because of you as well. Thank you a lot for that.
• Cryptocurrencies
  Last quarter should be (way) more bullish than the last nine months. Generally, 2019 should be better. I still think btc could be around 15-20k$ by the end of the year, more or less. Anyway, at first we need those 10,000$. Before that it simply is quite sketchy and insecure.
• Content crowdsourcing on Steem
  Moreover on Steemit, I guess? Yes, it seems to be a good idea although I really do not have any time for participating at such ideas/concepts right now.

Btw. what is that @steem-ua thing? I read about it several times but I am still not sure what it exactly is - I am pretty sure you have posted about it a lot too.
