Well, gold has never been the reason for crisis. Rather, gold was the escape from crisis and a way for one's wealth to be preserved. If you were smart enough to have gold, then you were kind of immune to the price hyperinflation and misery all around you, and after the crisis is done you emerged even stronger than before. But as far as my knowledge goes, gold was never the cause behind the crisis.
Gold is not used as a payment method. It is impoprtant to point out that it is impossible to start a crisis just because one single factor (for example US government could be partly blamed for the 2008 crisis). Similar thing should happen with crypto. For now I can imagine a scenario where Bitcoin is getting more popular while banks and governments are not going to integrate it into their systems which will lead to disbalance and crisis in some spheres. Hovewer it is less likely to happen in the next decade and there is much more problems in traditional economy of major countries that can cause crisis.
