I just joined a few days ago. I have almost no Hive. People had to lend me coin in order for me to post. Judging from what yo said I guess I send over eth from metamask to my Hive wallet and then pick up some coin?

As far as what I know - I'm a total n00b. I'm still wrapping my head around Hive and ecency points; and hive keychain. It's a bit of a learning curve but it's been fun.
