To date, the economic situation in many countries is in critical condition. Can the next financial and economic crisis be a transition to global use of crypto currency in international settlements?
It's an interesting thought for sure.
I've personally always thought that some sort of global financial crisis could be helpful in terms of getting people to adopt bitcoin. Especially one that has inflationary consequences, with rapidly increasing prices and CPI overall.
For example, just look at individual cases like Venezuela and Turkey, where bitcoin is definitely helping individuals to store their wealth away from their fiat currency, and thus leading to more adopters. This could happen under a global scale as well. Whether or not this actually evolves into a global payment network is another, but increased adoption of bitcoin as a store of value internationally is definitely possible under these circumstances.
