OK, so other than Bitcoin and altcoins, the only other anonymous ways of storing value that I can think of are cash and precious metals. Are there any others? Or is it just these three?
By the way, precious metals are not an anonymous way of storing value, unless you buy some jewelery (and this is questionable too). But jewelery is not a particularly good store of value. When you buy a piece of it, you pay for the work plus metal, but when you sell it, in most cases you are paid only for the scrap metal.
