Do remember that the government's only promise is to accept petro at the value of a barrel of oil's worth of bolívares (VEF), a currency that's experiencing hyperinflation thanks to... money printing! Oh, and at which rate? They set the rate themselves. The whitepaper says they'll use a formula with a discount rate of at least 10%, and no upper bound.
