- Steem: this is standard cryptocurrency/token tradeable on the crypto exchanges. You can power up to Steem Power.
- Steem Power: these are what the miners obtain and what users use to vote on posts. Can be powered down to Steem to cash out, takes two years... you get weekly payouts
- Steem Dollars: a token pegged to the USD. You can trade between people, but needs to be converted to Steem. Supposedly there will be an internal 'ecosystem' of people trading and using Steem Dollars...
Honestly, the whole system seems easily gameable and I'm skeptical of why it was set up like this. I will quickly move over to a more straight forward decentralized platform one starts gaining momentum unless other convince me why not. Hopefully as I learn more it makes more sense.
