While the government “appreciates” de Boliviano currency, the Central Bank has been lowering the exchange rate to the dollar. In the last year, the rate went down from Bs7.20 to Bs6.99 per one dollar. That resulted in some Bolivians traveling to Salta, Argentina to purchase dollars. In Bolivia a dollar in Argentinian pesos is worth 4.40; in Argentina the exchange results in 4.15. The difference, proximity, $30K limit per day with only a Bolivian ID makes this attractive. In sum, Bolivians still see the dollar as a better way to preserve their savings.
