This coin is a totaly shit look at buy support.
Buy support doesnt mean much especially at those volumes.
It only takes a guy or two to decide they want to put a mere 100BTC on the coin in order to like double the price.
The way i see it the coin has find its low support level and people are slowly amassing. Thats why we see those spikes.
I personally took a nice position in DCR, beyond the giveaway of course, and still grab a few every now and then at dips. I dont feel any anxiety about it.
But dont take my speculation for granted. I have erred before.
