Yes, bolivar is still hyper-inflated, thus there is likely a capacity/value issue related to only accepting USD: accepting Bolívares would possibly require the BATM to have a pretty large deposit for the bank notes. New bank notes have been released within the past few months, with a value of up to 50.000 Bolivares (100 fold up from former current largest bank note, but still with a value of 2 to 3 USD). Then there is the inflation effect of the bank notes losing value from one day to another just by sitting in the BATM until they are deal with administratively.

As to the extent of preference of BTC over USD, I’ll relay the question on the Spanish local board to try to get some inner insights.

Looks like they beat them to the BATM placement, but not to claiming being the first on the news (with enough coverage) ...
