Why not wait until silver comes out of backwardation. Some say that won't occur until silver hits $50+ and the firm grips start to loosen on the physical.
Silver's been in bacwardation for months now and the arbitrageurs won't even try and capitalize on it because it's getting extremely hard to get silver. If they sell it now they are not confident they can pick it up in the future at a lesser price. Unlike soft commodities, this is very bullish for silver
