Yes, I know him. I lived in Brazil for about 10 years but now I live in Portugal. I am leaving hive and I am going to steemit because some people do not understand what is a technical article (numbers and facts) or an article where I post my opinions about coins. I have been heavily downvoted by people that do not understand that the data comes from some sources that I indicate in every article and not from my mind. Is this group on steemit or only on hive?
