In 1990 President Fernando Collor formulated a plan with a radical package of economic measures, including the confiscation of bank deposits and until then untouchable savings accounts of Brazilians were confiscated, and Brazil plunged into hyperinflation.
1990 is 27 years over, let's hope it won't happen again! If you now trust Brazilian Central Bank, you can store Brazilian reals in the national government bonds. Crypto currencies are a financial pyramid scheme, so to keep money in them would not recommend more than 10% of the savings (IMO).
Thank you!
