it's free, but I will not resteem something I don't like, write quality posts and people will resteem you automatically, but in my group is not free to post but resteem is free, you can resteem all people from the group for free you are welcome to do that ☺ but the group is not free ! I worked hard for 7 month to make it big ! and we also upvote the post that pays, people are paying 0.1 and getting upvote of more than 0.2, so they just double money with us ☺
