It would be wise to also read up on what HIVE and HIVE BACKED DOLLARS are. How the hive eco system works here.
articles by @geekgirl @taskmaster4450 are very helpful.
Also dont forget to stake your hive coins into HIVE POWER once you get em, to benefit the blockchain everytime you engage in upvoting. The more HP you have, the more vote value your votes have (which means the more you reward others for using this blockchain, not to mention you get a portion of this reward back yourself from your own upvoting - this way we keep the ecosystem alive).
I'm a bit familiar with Hive power and how Hive works, I'm still learning more about different communities now because they have their own rules and what not. The reason I do is I had a steem account 3 years ago and it's almost a copy of Hive.
You're an OG!
