TL;DR - Embracing Bitcoin will not be the downfall of the US financial system; rather, it will save it. This demand will be good for Bitcoin, too.
There is no doubt the largest market for Bitcoin trading is in the US. Bitcoin and dollars are traded for each other more than any other fiat-Bitcoin pair. The USD remains the highest volume asset on the global stage, however, trust in the dollar wanes on it as well.
A great amount of uncertainty remains about Bitcoin in the public, but the public is becoming increasingly aware. At some point, the "then suddenly" threshold, when uncertainty about the dollar matches the uncertainty of Bitcoin in the public eye, a great and rapid flip will occur.
Retirement Will Become Impossible Unless Backed by Unprintable Money
It is this flip that will cause enormous and unprecedented loss for at least the aging population in the US, as well as holders of large amounts of cash. Let us focus on one aspect of this great loss: social security, which is already known to be at great risk, an almost certain bankruptcy of the whole system only a few years away, and this is only if the US dollar lasts that long.
The responsibility of this failure rests on the shoulders of the US Federal Government and the Federal Reserve. Salvation for the system will only be in one manner: backing the fund with Bitcoin.
A Strategic Reserve
If the US Government funded a strategic Bitcoin reserve rather than wars, the issuance of USD could be then exchanged for payouts in the form of Bitcoin. Retirees who depend on those monthly checks could instead receive Bitcoin. This would be reparation for the theft of the wealth promised by the system to begin, and it would be an efficient way to do so.
While the USD-BTC rate is still in the 5-figures, investments into it can see returns of hundreds times by the time Social Security becomes fully defunct. This window of opportunity is quickly closing. Returns in the tens of times should still be possible for a few years, but likely not past the year 2029.
This Will Also be Good for Bitcoin
The urgency is high. To avoid a cataclysm for our aging population, the US needs Bitcoin, and because of the demand this will generate, the adoption and valuation of Bitcoin can accelerate.
This is but one mode that Bitcoin will save the US economy, and more is to come.
