30K IS NOT A LOT OF MONEY THESEDAYS
if you live in a good area and are wealthy its not unreasable to think some people have cash or even gold well in excess of 30k
maybe he took precautions ,had it stashed in a safe or split up in various locations around the house
someone who is practically famous for doing big deals face to face for the last few years would need to have operational cash on hand in case the phone rings and someone wants to dump some cheap btc ASAP to take advantage of the situation and make a profit etc
Yeah right. Personal face-to-face trades with anonymous people, done nearly daily for couple of years. With no single instance of violent crime.
Maybe someone will dump some bricks on your head to make you understand what's wrong in your picture.
