Yes, all reasonable paranoia. However I do trust Coinbase/GDAX as far as BTC, ETH LTC are concerned.
It's a pain to store a few K USD worth of altcoins in my hw wallet (which I'm not even sure supports most of them). What if I'm at work and an event happens that makes me want to sell? The wallet requires an app to be installed.
If there's a hint of an issue with Bittrex, I'll trade to ETH and move them to GDAX.
Based on my research it seems like Bittrex allows the trading of Tether and lets people cash out to USD. Poloniex also. Seems like a round about way of getting USD out of Bitfinex.

Am I being a fool here?
