And this is why you don't dump Darkcoin in a panic kids. That monster dump of 15k @ .00098 last week... that guy must be feeling pretty sorry today.
Well, actually, the joke might be on you

That could have been a very experienced day trader who's been trading in and out of DRK since it started moving significantly a month ago. They might have been making money on every rise and every fall.
You're just looking at a single trade. You can't tell if that was simply a profit take from a longer term trading strategy or not. Not everybody is a long term investor.
To day trader whales, markets like this are just a way to accumulate more Bitcoin. They don't care what the price of the day is as long as it's moving. Also, they don't worry about getting "left behind" because they're in and out of this coin the whole time. Whenever you see a big buy or a big sell there's probably a 75% chance that that money has been going in and out of the market about 50 times.
Well actually I was buying those sells with both fists. It remains to be seen if the joke is on me. I haven't realized my gains for the most part. Time will tell.
