This latest dump was the result of a margin hunter. Someone sold about 1000 XMR under 235 and immediately a trigger order of 11000 dumped to market, this was the result of a long position getting stopped out or liquidated
nothing to worry about here hodlers!
Could also be a stoploss being hit. Anyway, trading on margin is very risky in such a volatile market as XMR.
Yeah that's what I mean, someone went stop hunting just below 00235. I'm fairly confident that the wick to 0026 was the bottom of this dump
I hope so

In addition, I would like to see Poloniex publicizing the margin data, just like bitfinex does with
https://bfxdata.com/. This would make things a lot clearer! For instance, we could've made a conclusion if today's dump was a margin call or not.
EDIT: Another dump, now that probably everyone who took a margin long when we significantly went up got margin called, it's time to go up again :-P
