Apparently US is preparing to print a lot of paper cash.
Rumours have been going on saying they are on the verge of printing 31 million USD. I wouldn't be surprised at all. And I believe this has been having a direct implication on the bitcoin price.
Your link makes no mention of $ 31,000,000 worth of money being manufactured. Where are you quoting from?
As to minting a One Trillion Dollar coin - a more lasting impression in people's minds would be a one trillion dollar coin minted on a planchets made of Plutonium.
