Historically, the pricing power of the USD has always gone down. And most currencies become worthless, before another "gold standard is created." So the scenario that the pricing power of USD declines so much that it is almost worthless is definitely possible. However, with the continued declining volume of Steem on poloniex and other exchanges day after day (https://coinmarketcap.com/exchanges/volume/24-hour/), what would make one believe that the USD being worthless is the more probable scenario? Thanks!
