Paper and silver are better if they are kept for a long time. The paper-silver spread is equivalent to the fund's subscription and redemption, which adds up to about one point. The subscription and redemption of funds are higher. Of course, if the subscription can be discounted, it may be slightly lower. The silver fund has management fees and custody fees, which add up to about 1. 1%. The increase of silver in the early stage may be only a few or a dozen points per year. This loss is relatively large.
