Public service message:
When you trade OTC you engage in a transaction with people you possibly know nothing about. You may send your BTC to the person, and never get anything back. Or you may send your $currency to the person expecting BTC, and get nothing in return. This is a highly undesirable outcome for you, and you should do your best to guard against that.
