hm that's not bad if you think of it: 1 Steem Cent = 5 US-$ Cent and it only took me like 5 seconds to get that done. That's (theoretically) 12 per minute or 720 per hour. 720 * 5 Cents: 36 US-$.
You'd have to screw up quite a few blocks in the blockchain to get to that value. But then again: I'm sure you could beat that...
