The only thing that I can possibly say to such a remark is that you are completely clueless. I say that not as an insult, but as a matter of fact. Google is your friend (at least in your case). I am not going to give a broad tutorial, just pose a question: you actually believe that in an age of internet banking and crypto currency that you must transport your own gold -- or even yourself -- to a foreign vault to store precious metals (either segregated or unsegregated)? Century-old Swiss companies have adapted to the computer age.
In fact, if you have enough money you can buy physical gold on the futures market (at least in the U.S.), pay little or no premium (unlike the huge premiums on coins), and have it all transported from a vault in the U.S. to a vault almost anywhere in the world. You can choose either segregated or unsegregated storage. And you don't need to leave your home to do it. If you have less money, you must pay premiums but the process is even easier. You can even have your PMs transferred to a vault in a free zone at an airport.
