By living more frugally and not spending money on things that are not so important, this is the best way to deal with hyperinflation.
But actually living in these two ways should be done at all times not just during times of hyperinflation because the more we spend, the more unstable our finances will be, especially if there are not enough jobs to earn money.

Depends on what kind of crypto you mean but if the relationship is about bitcoin then I quite recommend it. However, if it is related to hyperinflation then it is best to control the problem first and when it is stable then think about investing wherever we want.
