I don't know what banks you're talking about reducing withdrawal terms or engaging in crackdowns as they go into insolvency. The banking sector is thriving in the US and bank profits have been high for several years. The banks are healthy in that they routinely pass stress tests and even the most at-risk banks have improved to the point where the Fed is approving expanded dividend and capital repurchase plans. Derivatives remain a systemic risk, but that has nothing to do with Bitcoin. There are Bitcoin derivatives as well (futures are derivatives).
I don't see he connection between Bitcoin and national debt. If the economy was denominated in btc, it would still be possible to have a national debt. That wouldn't solve anything. The fact that the government any control Bitcoin is why the economy will never be denominated in btc. Pretty sure it would be a bad idea anyway. We left the gold standard because it hampered economic growth.
European banks limiting withdrawals as they face insolvency and also cutting the maximum amount under which insurance protects depositors accounts are threads which have been made in this section over the past 6 (?) months.

There was an article posted in this section not long ago regarding some banks cutting depositor insurance.
In searching for these links I realized its difficult to find sources via search engine for negative news on the economy. This reminds me. There used to be a website called
http://www.eudebtclock.org which used to keep track of total EU debt(in trillions). I think they got shut down last year in 2017.
Where things get interesting is, if someone tries to find out how many trillions the EU is in debt via search engine. Its very hard to find the total amount of debt listed in trillions of euros. Its listed as a percentage of GDP or whatever assorted statistic. But the total amount of debt -- its almost as if an attempt has been made to scrub and censor the data from the internet.
Bank stress tests don't do anything. That aspect of regulation has been subverted and gamed the way credit rating agencies have been. They didn't prevent the 2008 economic crisis. They fail to prevent economic crisis in greece or any other nation. Banks should not be expanding their programs due to concerns over the economy.
Danger posed by bank derivatives to anything in bitcoin given the ridiculous monetary amount of exposure banks are subject to. There are banks who have 4 times the GDP of the united states in derivatives exposure. $70-$80 trillion per bank in worst cases. Bitcoin derivatives: insignificant in comparison.
Bitcoin contributing to economic stability could revolve around the concept of the competition bitcoin gives banks driving innovation, progress and industry advancement. It could also help to preserve wealth should the dollar crash which would help in the event of a recovery, etc.
I'm not up on the status of EU banks. US banks are much improved health-wise from 2008, but the problem is they were "too big to fail" before, and they only got bigger as they used government loans to snap up failing rivals in 2008 and are now much more of a systemic risk than they were in 2008. Stress tests are the best gauge we have for measuring preparedness, and banks regularly failed them in the years after 2008 in the US and the government required reforms because of them. The fact that they pass them now shows improvement. Again, I don't know how things are in the EU, but Greece is a perfect example of a country that can't fix itself because of an ingrained culture of tax evasion and an overly large welfare state. Bitcoin, an instrument that can't keep a stable value hour to hour, isn't going to be a bastion of stability if the USD fails. I just can't see how that would work.
One thing for sure, if the US doesn't stop running ridiculous deficits, it's going to end up like Greece. The problem isn't unforeseeable, but no politicians here have the political will to take a common-sense approach to fiscal discipline and the American public is far too stupid as a whole to demand accountability. We want wants fulfilled now. Low taxes, big government programs, bloated military, foreign interventionist wars forever. In a word, ridiculous.
