The exchanges have been buggy lately, but it seems TradeSatoshi has smoothed out now that their server migration has completed. Not sure whats going on at stocks.exchange though i think they had some server maintenance going on too, but I stopped using that exchange due to ridiculous btc withdraw fees. I really hope the BarterDex exchange will be working soon. I haven't had any luck with it and since yesterday my BarterDex app won't load. C-Cex is a complete joke, I wouldn't go there if they paid me.

I think many of the exchanges were doing maintenance during the holidays when traffic was lower, and some just didnt get all the bugs out before the rush of Traders after the holiday.

I myself have been critical of the exchanges, however after a bit more thought and research I think this project is on the right track. We need to stay on the smaller exchanges for now, at least another 6-12 months. The difficulty mining is already through the roof, a big exchange would put us back on whattomine and at that point, the time for investment-oriented mining will be over.
