Problem with bank transfers is the fees. Do it all at once if you're going to do a transfer...
If you are interested in buying gold, the risks to keep in mind are...
It can get stolen unless you keep it in a safe or a safety deposit box.
But, then again if no one but you knows you have it, why would they steal it?? Hide it well in case of a break-in and insure it! Loose lips, sink ships.
Also, you can buy it all over the place, you will have to check where you are, but just google "bullion brokers" in your local area. You can buy up to $50,000 in australia with no trace of where your money went, or came from.....great if you don't like people watching what you spend on.
Of course, it can fall in price and you lose money, lets say you've bought it for 1000CHF an ounce, there is possibility it could fall (but with the US market the way it is, its not likely) Silver is actually a better bet right now, but you have to buy that by the kilo, so transporting alot of it gets difficult. you can put your money into a "silver saver" account, this means they invest your money in bullion instead of a normal bank account, this is a great way to go as you can cash any time you like, and they hold the silver for you. Personally I prefer to have the bullion with me and not in someone elses hands....
Read up about "Fiat" money, all money is fiat money except for a few countries who still back their dollar with precious metals. Fiat money is a con, and a rip off, if you buy gold you have a limited resource. There is only so much of it on the planet!
Do a google search for "silver saver" accounts, "bullion brokers" and "fiat money" that's your homework for tonight. Enjoy!
