During the Bitcoin Week event, the President of the Republic of El Salvador, Nayib Bukele, acknowledged the Bitcoin donation by the Liberland Aid Foundation for the Benjamin Bloom National Children's Hospital in El Salvador. The donation (which included an entire BTC), was funded by voluntary donations by Liberlandians. Some of those individuals were present at the announcement.
El Salvador requested the World Bank's help with its transition to add Bitcoin as legal tender. The World Bank flatly refused. However, the World Bank's own charter may force it to at least accept Bitcoin, if nothing else.
