Robert Kiyosaki, author of Rich Dad Poor Dad, has criticised the debate over which is better, bitcoin or gold. He stressed that the only fact that matters is how much gold or bitcoin you own, noting that $35 trillion of US debt is the real problem. Warning that the bond market is collapsing, Kiyosaki argued: "Dollars are junk. Stop saving dollars, fake money... start saving gold, silver and bitcoin... real money."
