I am trying to do something very quickly. (Over the next few months, I expect things to change greatly.)

I understand your concerns. I believe that the presence of a "former Federal prosecutor" within Coinbase will be approximately the least of my worries. I fully expect that everything I do will come under the highest level of observation.

And yes, I understand the issue about holding one's private keys. (at least, from a beginner's standpoint.) I have read up on the subject of Mt. Gox, etc.

Soon enough, I will have my own BTC wallet. (Actually, I already do, but I don't trust this.) My immediate concern is that I am not sufficiently confident in my ability to reliably maintain such a wallet on a small, ordinary personal computer, 24 hours per day, etc.. Obviously a crash could be a disaster. I have decided that at least for a few months, placing this on Coinbase is a reasonable compromise. I am not aware of of an impending liquidity problem with Coinbase.

There are other considerations.

    Jim, I strongly suggest you close your coinbase account ASAP.

    "We are excited to announce former federal prosecutor Kathryn
    Haun has joined our parent company Board of Directors."

    "federal prosecutor with the U.S. Department of Justice and its
    first-ever Digital Currency coordinator."

    "She also held a significant role in the case of two federal
    agents’ role in the investigation into Silk Road."

    Jim, coinbase is THE ENEMY.

    Also, you are NOT using bitcoin if you use any middleman. You
    must use a bitcoin client and you must have control of the
    private keys. If you use coinbase or any service like that THEY
    OWN your bitcoins, not you.
