I do still trust poloniex, I've been using them for years and despite there are some problems that others are experiencing. I don't have any problem on them so why I don't have to trust them? It's trustworthy people.
Yes, you are right because even still, I never faced any problems with the Poloniex. Still, I am happily trading in that exchange due to miss propagation from the people leads to makes to raise some question about Poloniex. But for my knowledge still, polo is the safest exchange.
