From poloniex, thought it would interest some of you here:
Regarding speculation: I am wondering if the dump guy is done now (could be several guys, but his blatant market dumping makes him unique I think). I still have a hard time comprehending why one would dump with +5% slippage, whereas he could've set up some asks and patiently wait until they got bought.
I agree with you. No point in dumping like that. Dumping is more understandable if there is space to go down and buy lower.
However, the lower it goes the more there is competition for these scarce treasures.
At some point a dumper end up having tons of bitcoins and a shortage of Moneros which is not that good situation to be in.
