I like this perspective.
Another interesting note regarding SBD. I used to think SBD always needed to be transferred to STEEM to cash out, but poloniex has an SBD/BTC exchange.
I don't have to deal with that 10 day delay to cash out, and can let my SBD collect 10% interest if I am not in a rush to exchange it.
Poloniex, Bittrex, Hitbtc, and Blocktrades all support direct SDB/BTC exchange. Shapeshift seems to support STEEM but not SBD.
Note: I advise against using Hitbtc and make no recommendation either way on the others.
Where is that 10 day delay to cash out?
There's actually about three ways to sell/convert your steem dollars. You can convert them to steem internally (which takes one week). You can sell them for steem on the internal exchange at steemit.com/market (instantly). And you can transfer them to an external exchange like Poloniex or Bittrex and sell them for bitcoin (instantly).
