When/if the premiums come back, people will probably try to sell first before peeling imo. There are nice brass cas coins on here listed for 1.2BTC and not selling, why would anyone want to sell for less than that? The inherent risks/hassles are not worth the reward. The pool of buyers around here has pretty much dried up and until there is some new blood with deep pockets I dont see much changing in the short term. Maybe some sort of advertising( ex. having a physical presence/table at major coin shows) could draw in new people?
