Hello,
I took a break from trading altcoins, last time i was trading altcoins i used websites like mintpal polonex cryptsy.
I want to invest and trade altcoins again. What are the websites you guys currently use for trading altcoins?
Poloniex is still stable,site those who are not yet on your list are Novaexchange and CCEX which I'm actively trading security is tight and great on both exchange they both have google authenticator ,you might want to try this two,it's not hard to get it on anybody's list.
