as I have been pointing before, someone is having a fresh daily source of almost free coins, I think is someone manipulating the mining network, thats why a lot of people are having orphan blocks and yeah a pool controlling 80% of hashrate can do this with other separate entities so is not that obvious.  I think what happened on C-Cex is only correlated for the massive pump and 1 dump on poloniex but I have witnessed and participating in the buying of 14 more dumps in the .0010, .0009 and now .0005.  The number the dumper chooses is correlated with the btc bounty, if someone putts an ammount above 20 btc in .0005(buy order) the guy will sell at that price.

The first dump is as old as when you guys reached the .0024 level for the first time, we just didn't notice them bc the market recuperates really fast(les than 3 mins) at those crazy prices.

if I had to guess, what hapened on c-cex had something to do with XCP hacker or the poloniex owner destroying competition bc he was attacked before with this bug and therefore familiar with it, steal from competition and launder your money in your exchange.
2. what is happening now with pools will have to do with the dev or someone in his team or someone found a way to use litecoin asics on dark and is exploting this ussing different users and solo mining to hide this.

basically the dumper can withdraw easily BTC from poloniex but not crypsy or C-cex, so the guys that buy at those cheap levels are laundering his btc by selling them on crypsy and rebuying on polo.
all theory......
