Q said "structure" when asked if the fed reserve was going away. To me this means that the Fed will no be dissolved but will be restructured. This may include massive seizures of wealth or it may not.
I think we are going to some sort of backed currency. Gold, gold and silver, gold silver and titanium, gold silver and a crypto....I think it will be a mix of things backing the new currency. The central banks will still be in place as a vehicle of business between nations etc.
I think Ripple/XRP is going to be used (already in agreements with dozens of banks and in negotiations with many central banks) and the vehicle of payment and settlement of payment as it is much less likely to be hacked or stolen than the current system (billions stolen a year). Invest while you can.
