Tab clear-out... According to the Argus a few weeks ago, "[the] currency has shot up in value by 3,000% only days after its launch because collectors are selling it on the internet."
I'm wondering about this. Is it better to leave this to happen and accept that x% of the currency will "leave" circulation? Or could you somehow "auto-expire" physical notes after a certain period, and maybe renew the expiration date once they're used to buy something?
