Thanks for your thoughts shibaji. I mostly agree with your sentiments.
I also started out on the same road as you;
Bullion -> Perth Mint -> Pandas -> MCCs
The ability for us to discuss sales threads politely (and safely) in the Panda Forum has been a HUGE blessing - which has led to wonderful and entertaining knowledge exchanges (e.g. Bronze medallions, NGC conversations, etc).
In the past, before the Panda Forum, it was very difficult to discuss or trade Pandas and MCCs at Silverstackers without significant trolling (and constantly unhelpful rude remarks). I sincerely hope that we have moved on from those days, especially since so many contributors from around the world have added their valuable thoughts here, almost on a daily basis.
I am grateful that GP has allowed this Panda Forum to exist. He has been very generous to allow us all (especially me) to participate in this playground. He has been a very hospitable host and allowed us to run this place "laissez faire" . Many thanks GP! Hopefully I can play host/tour guide to you if you ever come pass Shanghai!
However, from the Administrations point of view - the ability to trade in the Panda Forum has created a loose end that could be used to circumvent certain constraints. Thus, our Revolutionary Comrade GP has decreed:
"all trading be centralised into Buy, Sell and Swap" [sounds like an exciting 5 year plan]
