That can be a trap set up by FED. So never ever execute a trade of several thousand dollar at once. There were incidents where people got arrested for selling huge amounts of bitcoin for cash. I have given few links below which you can read,

So my suggestion is to stay within your limit of few hundred dollars and ask for ID of the buying party. Just to be on the safer side.
