The statement is well-supported by the evidence. Source 12, a news report from Anadolu Agency, explicitly states, 'Central American country El Salvador will continue purchasing Bitcoin as its strategic reserve, President Nayib Bukele announced.' This is a direct claim from the country's leader. While the word 'indefinitely' is not used, a policy to 'continue purchasing' with no specified end date strongly implies an indefinite increase. This is corroborated by Source 1, which notes the government 'is increasing its Bitcoin reserves.'
