Hi cashflo.
I understand you being a little wary, but I do think you are worrying about a situation that is not likely to arise.
Being able to trade and set the price you require is a big plus for me.
There is a question saying.
Might no-one be bidding a fair price for my gold when I want to sell.
Their answer to this question, is the sitution is unlikely, but this is another reason where you would be able to take physical possesion of your Gold to sell elsewere,which you would do if prices were consistently better somewere else.
We shall probably agree to disagree but it`s good to discuss the issues involved.
Regards.
