The coin is abandoned by the dev, the price went down, so it became unprofitable to mine Aeons.

And I don't now if you noticed, even though the overall hash rate went down, the complexity of the blocks is pretty high. I know at least a couple of other CPU coins 2x more profitable than Aeons. so, why would one mine it if he could simply mine something else - sell it and then buy x2 more Aeons for the same hashrate

Right now the speculative people who don't care about mining and a real coin price in relation to HASH per $, dropped the price, so unless the price goes back to 24K the coin is doomed. Big holders of the coin should consider setting a buy wall at 22K on hitbit, it would benefit everyone, and bring back the miners

And to be honest, there is no reason right now, for Aeon price on hitbit to be so low, and there is no reason for bittrex to maintain the wallet for so long, so I guess, either bittrex doing this intentionally or out of negligence, you pick one, because there are no technical issues with the block chain right now it works flawlessly.
