The last crisis that we lived was probably the first financial problems that the economy's faced with the presence of BTC and cryptocurrencies, but it was too early for consumers to see it as a secure alternative to the problems we were into. But political issues exist right at this moment (example, Venezuela) and we are facing a growth in cryptocurrencies which may lead to some of the countries with problems to adopt a digital currency.
Consumers wont switch voluntarily to crypto because they are not informed and this world/technology is not super easy to understand and dominate.
