If you want to understand better current state of global financial politics and actions of central banks and the effect on the economy, US-Dollar as a reserve currency, gold and blockchain technology I do highly recommend to listen to the podcast or read the interview of Mike Gleason, director with Money Metals Exchange, with best in class analyst Mr. Jim Rickards (also author of several bestselling books including The Death of Money, Currency Wars, The New Case for Gold, and now his latest book The Road to Ruin, which I do highly recommend!)
