Swiss campaigners have decided to abandon their efforts to initiate a referendum on the Swiss National Bank's (SNB) bitcoin reserves. According to NS3.AI, the campaigners were unable to gather the necessary 100,000 signatures, collecting only about half of the required amount. The proposed referendum aimed to amend the constitution to mandate the SNB to hold bitcoin in addition to its gold and foreign-currency reserves. However, the proposal did not specify the allocation of bitcoin within these reserves.
