Firstly, that's a very good point Lovesilver makes.
Secondly, any 'answers' made to Kentaro's original 'question' are totally unsubstantiated and therefore meaningless.
Probably a better way to go would be to seek members' opinions on what they think a reasonable percentage/proportion of their assets they would like to have invested in silver, and in what form.
Finally, the thread has already seen a couple of posters squabbling, and that's just silly - particularly on a thread that carries no depth or importance.
