The hive token and power up and ressource credit
if you endup with a not enuf RC to menetiuze one of your post.
RC stand for ressource credit, it the system hive choose to use to limit the amount of post you can monetize for obvious reason
you start with about 3000000000 of them rc
posting cost vary but are around 1000000000 rc by post
When you get the red message saying you can monetize because you dont have enuf rc you :
wait for some time, a few day up to five
or
buy hive token and go thru a process called power up
powering up your hive token will give you more ressource credit aka rc and allow you to post mpore monetized post. i have yet to find actual number by hive
on the down side, once powered up you will not be able to power down on the short therm because it is a slow 3 month process
