I own a 1 oz silver minted seat, worth around $800 in bitcoin right now.  I do not see anywhere on how to withdraw the bitcoin from the physical coin, or if I do so, does that mean that I no longer have a seat that will continue to generate bitcoin?  I have read tolns of reviews and blogs, and there is no information about it.  I know there is a hologram on the coin, but do I need to peel it off to get access to withdraw the bitcoin?  And again, does that mean that I will no longer be generating bitcoin on that seat?
