Yes, an interesting situation. The Venezuelan government, represented by President Maduro, has launched an economic war with the United States and its dollars, and now they recognize that dollars are good for the country. Moreover, neither the national cryptocurrency Petro nor the transition to the payment of pensions and other payments in bitcoins saved the Venezuelan economy. Cryptocurrency did not help here, probably due to inept management of the economy.
The problem of introducing high technologies is also raised here. Practice shows that you should not fully rely on them, along with them should be back-up options for conventional technologies. Therefore, do not give up cash.
