Apparently I suck at reading the markets. I shorted the heck out of BitUSD when BTS was at something like 10,000 satoshis, which turned out to be about our all-time high. Not long before the balances unlocked, I bought a ton of BitUSD because I was expecting us to take a beating -- I think it was ~50M new BTS were unleashed? -- but we rose instead. Aaaagh!
Fortunately I took the opportunity to short to myself at 0%, so I'm not entirely long BitUSD and I did realize some of the gains.
