Attempt to learn

I have been on Ecency for a couple of months now, hoping that I'll pick it up along there way.
My impression of Hive is that it functions just like a Beehive, the combes represents groups amongst the community of busy bees.
What confuses me is its suppose to be a method of earning crypto which focuses on being decentralised but how is hive decentralised?

Like I said, this is all new to me. I am not learning by watching, so get involved, dribble and fingers cross Ill pick something up.
