I wanted a reliable, legit exchange with good, responsive support - am I wasting my time with Polo?
Yes. Honestly, you should just give up and try a different exchange. It's been a while since Poloniex is in decay, "going backwards with its volumes"[1] and never improving their support. If you want to trade altcoins, I recommend you to try Binance (it doesn't require any KYC/AML verification).
While I completely agree with what TryNinja said, I very much doubt that Poloniex is experiencing an influx of new users -- this exchange is only going backwards with its volumes, and everything points at an outflow of users instead of the opposite. Less volume means less usage, which should be an important and decisive indicator. Binance is swallowing the far majority of the users, followed up by Bittrex, which opened its registrations very recently. If this downfall of Poloniex continues, and I have no reason to think otherwise, they will be covered under a thick layer of other exchanges doing better business. Feel sorry for Poloniex though.
24 hour volumes.
Poloniex 6400 BTC
Bittrex 70,000 BTC
Binance 200,000 BTC
Sure, Verge is pushing some serious volumes, but even without Verge, Poloniex heavily lags behind, and that for months straight, and only falls further.
