1. It's extremely undervalued due to manipulation & paper market
2. Due to extremely low price, silver's not recycled because it would cost more then the metal itself
3. Mining production decreased because price is too low
4. reached peak production in 2015.
5. JP Morgan manipulation by shorting silver price & buying it back by requesting physical delivery (look up Comex physical delivery, they request the maximum amount each month) (my favorite reason)
6. When oil prices go up, it will cost even more to operate the mines and if price of silver is still low, mines will close

If I'm wrong about any of the above, please correct me.
