permit the state to invest in Bitcoin.

HB 1155 amends South Dakota's investment rules to allow the state to allocate up to 10% of its investment funds into Bitcoin. The bill specifically defines Bitcoin as a digital asset meeting strict network criteria (starting from its 2009 genesis block) and requires all Bitcoin holdings to be stored through secure custody solutions or qualified custodians. It applies only to state investment funds, not individual citizens or private entities, and explicitly prohibits investments in other digital assets like cryptocurrency exchanges. The bill does not authorize new spending but modifies existing investment guidelines to include Bitcoin under defined security and limit requirements.
