Why is Coinbase not allowed in Hawaii?

Can you please elaborate on why Coinbase, a popular cryptocurrency exchange platform, is not allowed to operate in the state of Hawaii? Are there any specific regulations or laws in place that prohibit Coinbase from offering its services in Hawaii? Additionally, how does this impact residents of Hawaii who are interested in investing in cryptocurrency and using a reputable exchange like Coinbase? Is there any hope for Coinbase to be able to operate in Hawaii in the future, or are there any alternative options for Hawaiian residents looking to invest in cryptocurrency?
