Venezuelans are struggling to carry out basic transactions like purchasing food as the value of their currency, the bolivar, has plunged against the dollar amid the country’s worsening economic collapse.

According to Reuters, over the past year, Venezuela’s currency weakened 97.5% against the greenback: Put another way, $1,000 of local currency purchased in early January would be worth just $25 now. The annual inflation rate in 2017 could reach $2,000. Though at least one other estimate puts the real rate of inflation closer to 2,800%.

Of course, President Maduro has blamed websites like DolarToday – which publishes the closest thing to an official black-market rate by surveying clandestine exchanges in Caracas and other cities – for the spread of black-market activity, part of a conspiracy organized by Washington and his local political opponents to force him from power.

One of the unintended consequences of the bolivar’s collapse has been a social experiment of sorts in the use of digital currencies: As we noted back in October, as many as 100,000 people are now mining digital currencies in Venezuela, defying a government crackdown that’s seen many of them thrown in prison.

But for those who can’t or haven’t resorted to transacting in bitcoin, an increasingly scarce supply of dollars is creating intractable problems for millions of Venezuelans, Reutersreported.

For many, simple purchases like a new tire for their car are simply out of reach.

There was no way Jose Ramon Garcia, a food transporter in Venezuela, could afford new tires for his van at $350 each.

Whether he opted to pay in U.S. currency or in the devalued local bolivar currency at the equivalent black market price, Garcia would have had to save up for years.

Though used to expensive repairs, this one was too much and put him out of business. “Repairs cost an arm and a leg in Venezuela,” said the now-unemployed 42-year-old Garcia, who has a wife and two children to support in the southern city of Guayana.

“There’s no point keeping bolivars.”
