what do you think of gold banks, where you have an account, and you can lock up your gold into investments, like monetary metals and earn yield off your gold like it was cash? Like you still have your gold, then you get 4% more gold in yield or however the investments perform.It seems like a good idea to me? What is the catch? I now the fees for montetary metals are 1.5% for a round trip, with a .75% fee for buying and selling gold with the account.
and how would that yield be generated in the economy?
