I don't know if this is proper UI behavior or not, really, but I find it funny.
On the other hand, Busy, Steempeak, and Ulogs.org don't display these transactions as all. On those front ends it just looks like SBD has been mysteriously disappearing from my account - and presumably in a couple of days Steem will start appearing out of nowhere.
I like this better than that, at least. But I think probably combining them the way delegations are combined would be a better idea. Or add some extra data to them - time of enaction, at least - if they're going to each get a line.
Dollar-cost-averaging this way is probably -ev, but I like having the ability to spread my risk out since I don't fully understand conversions yet. This way I get a lot of data. I should probably figure out roughly where Kelly is rather than just tossing in round numbers; it's almost certainly much higher than $100.
Fingers crossed that the market conditions stay this way for a while.
