Like I said, if you are not comfortable with SLV, there are many other ways you can invest in the most precious metal on earth, silver.
SLW, PSLV, SIVR, AGQ, silver futures or just buy silver coins from the US Mint. You can even keep the silver coins in your own pocket if that is the only way to make you feel safe about your investment.
The only reason I listed SLV was because it is the largest silver fund in the world. SLV is the most liquid way to own silver with plenty trading volumes for liquidity even if you are operating a fund. But you do not have to buy SLV if you are not comfortable with it. Owning silver coins is the only way many people feel comfortable about investing in silver. But it is not as liquid as owning a fund.
