Hello everyone,
  I am pretty new to BTC and other "crypto-currencies". I have been interested for awhile, and I've known about them....I just never understood all the trading jargon that comes along with it. Anyway, in the past few months I made some purchases/sales on CoinBase (mobile) and would like to get a little more serious about various coins. Recently, CoinBase changed it's identity verification stuff, and despite having a verified account, I can no longer use coinbase to trade. Anyway, I am wondering what platforms you all actually use to trade various AltCoins and BTC. Also, I have a BlockChain mobile wallet with no actual knowledge of how to use it. Is there a better/more secure storage method that would more suit the needs of a beginner? I have looked at a few hardware wallets, but I'm not very familiar with anything, really.

  My major concern is that, each time I find a website to purchase/sell currencies, I end up finding a boat-load of horrible/terrifying reviews about their system. Just looking for something reputable to get me started.

Anyway, any help is greatly appreciated.
