This won't be a good step ,I can agree on other fees but registration fees on hive is a bad idea ,did you no some people don't make up to 100hive as you claim in a month,many newbie find it hard to make a stand before earning penny on hive ,some even take up to many months before earning a reasonable amount ,you might think the 5hive is small because you are a big account but trust me some people don't earn that in a post , charging fees will drive many people away , remember hive is still on growing stage , little mistake can destroy everything we have build
