According to ChainCatcher, South Dakota Governor Kristi Noem vetoed House Bill No. 1193, which specifically excludes cryptocurrencies such as Bitcoin and other digital assets from the definition of "currency."

Kristi Noem said, “If cryptocurrencies are explicitly excluded from currency, it will become more difficult to use cryptocurrencies. By unnecessarily restricting this freedom, HB 1193 will put South Dakota citizens at a disadvantage in business.” (Source link)
