There's a explanation for that.
There are few Icelandic auroracoin community facebook groups with 1-4k members. There are two big buyers who have adds pinned in every group looking to buy all your auroracoin slightly below price for icelandic fiat.
Since there is no current use for auroracoin besides trading them for other cryptos, majority of all airdrop coins get sold to those two addresses for fiat.
Good explanation.
I've suggested exchange cold-storage before and was slaugthered for it.
Let's see how you will fare...
I myself have still not made up my mind as to what to believe.
