Bitcoin is different currency if ever we have an economic crashed or economic crisis, bitcoin will not be affected. The currency affected is Fiat money.
Crypto currency can help through subsidized the affected party through use bitcoin as a currency reserved to can pay all the debt of those financial institution affected
We cannot start pointing out any correlation at the moment, since thus far there has been no past scenario to look at to be able to know how things would end up working out. A lot of people may have their different thoughts based on different reasons, but for me, what brought about the deflationary nature of bitcoin and what urged the creation of bitcoin and its features was basically linked to the previous crisis. One thing for sure, most people who are investors and smart, would not want to be in fiat, and in such periods, assets tend to increase, hopefully, we will get bitcoin serve its purpose as a digital asset.
There is not clear evidence that there is such a correlation indeed. But some recent events point that fiat and crypto behave opposite.
If an economic crisis is going to blow then cryptocurrency market is going to go upwards as people will start seeking for other ways of storing the value of its money and resist the inflationary trends that will take place.
A recent example is the Turkish Lira crisis 2018 when Turks started buying bitcoin as they saw that their currency is losing value.
