Even though Hawaii residents have lost the use of CoinBase to purchase Bitcoin and Ethereum, there are alternatives if you look for them.
How to get BTC for Hawaii residents!!!!
I have found that Uphold.com will allow funds to be withdrawn from your internet bank account (in my case Bank of the Internet, BofI). I verified this by doing a deposit today.
You just have to activate an account of Uphold and go thru the usual security procedures of verifying your identity. There are no affiliate codes or rewards so I do not profit from letting this information out. Just a way to purchase cryptocurrency without going to localbitcoins which I consider a higher cost and an unknown risk.
Unfortunately, Uphold does not allow the use of debit/credit cards for funding from US citizens. I hope this changes in the future.
