You shouldn't use stocks. I sent some coins from there a week ago and still not in my wallet.
Also stocks uses our coins to build their own masternodes wich is clearly a no go! So I suppose to unlist the coin there and to stop using this crap exchange ..!
Before going into XSG I also did a lot of research on the current exchanges that offer it, and by far stocks.exchange had the most negative reviews out of any other. I would recommend not to use that exchange, save yourself the stress.
The only one that seemed to have the best reviews was Graviex. Unfortunately it's the least active of the other exchanges, but it is the safest...
