Hey Jerry,
I have had my share of problems on Poloniex from no return emails from the support and withdrawals that would error and I would never get refunded.
With my portfolio getting rather large I ended up pulling my coins off the exchange and putting them in individual wallets in which makes me feel a lot safer and comfortable with my investment in my hands rather then a possible Mount Poloniex. :) Thanks for the great post I'm sure it's getting a lot of folk on here to think about their individual investments as well.
