On normal days Polo does 90% of trades, so maybe there is the reason.
I have to find out what my PW to C-CEX was then. Too bad their email I have to click always takes half an hour. And today I am away for family.
Last time I sold for 750-800 and bought back for 630 a month later. Then it dropped to 400s 2 days later lol.
Current price is nearly 3 times the long time average so yes, unfortunately I think its going to drop again after trade normalises.
If not I will be even more happy then to make a good trade though ^^
We got confirmation from poloniex yesterday that they are looking into enabling deposits/withdrawals for Gridcoin, however it's still disabled at this moment.
In the mean time, the price of GRC has been pretty stable and rising again today.
