Manipulations for sure, but don't believe any of the ETFs are fraudulent. The market cap is 7 billion. These guys manage trillions. Every share is backed up. The price and NAV are steady without a variance. Shorts have used the SLV=SCAM mantra to scare weak hands out. They succeeded but those idiots were chased last free fall. New entrants don't buy into that BS. Eric Sprott's tried to get SLV and SIVR investors into his PSLV, using that mantra. It back fired on him.
If Silver increases to 500, SLV will increase the same %.
