I just verified at Mt. Gox and am pending verification at Kraken. However, I quickly realized that there were hurdles that I needed to jump through in order to get my USD into BTC. Coinbase was a much easier alternative.
What advantage do Mt. Gox or Kraken have over Coinbase? I realize it's quite easy to move BTC into both Mt. Gox and Kraken hosted wallets.
Is it purely anonymity, pricing, or something that I'm missing, like trade execution features?
