I've heard many negative comments about Venezuelans and how they only extract value from the Hive blockchain. This is said because they probably withdraw and power down more than other nationalities.

A quick study of history shows that "It is today, it will be you tomorrow." as H.I.M Haile Selassie I so wisely stated. The same folks criticizing those who power down HIVE could very quickly find the tables turned. Life has a strange way of throwing curveballs when you least expect it.
