Seems like you must know my thoughts.
It's only a matter of time before countries and central banks start printing fiat derivatives using crypto collateral. The only requirement for printing debt is a good source of collateral, and crypto is the best collateral there is over the 4-year cycle. It does indeed strengthen the dollar.
However, I believe that someone will eventually create a crypto that is stable without piggybacking onto fiat. It would simply have a superior and unique monetary policy that stops it from being volatile. When that happens all bets are off.
Unsure about stopping the volatility as it exists in lots of places. Maybe better balancing it out. Then resulting in growth from constantly minimizing downward volatility.
