I have invited a few across. One already had a Hive account for Splinterlands but I convinced him to start writing too! :-) Others have been interested when they hear there is financial capital available but not when they hear about how much effort I put in personally into my writing and curating. I try to explain that each person's contributions to Hive and POB are different. Some write. Some curate. Some just invest. Some do a combination of the 3. But the perceived complexity of blockchain and the terminology puts most people off, so I have started sharing @ryzeonline 's beginners guides to see if that will help make people feel more comfortable with the sign up process and being part of Hive and POB. Good luck with your friend but don't feel bad. I have the same feelings of frustration with members of my family and some friends who I think would be assets to the platform and benefit both socially and financially, but they have their own lives to lead and their own choices to make. Focus on you and your growth. If your friend was really interested they would have made a plan by now.
