Now, what your decision has convinced me to do is get rid of my Steem Dollars ASAP. While it is a good buying opportunity, I actually have to pay bills.
But for people who are wealthy, holding Steem Dollars makes sense because it's the least risky thing to hold in the system. Steem Power is nice but it's risky. Steem Dollars is risky if and only if it doesn't hold the peg, and I think eventually once it gets used in e-commerce or in trades on Steemit, it will begin to hold the peg, because it will be a situation like DIsney Dollars or Casino Chips where the only way to interact on Steemit is with Steem Dollars.
