CoinBase is a San Francisco based company that does digital currency business. I just wanted to set up an account (free) but since I live in Hawaii, I was rejected right away. I could not buy
Bitcoin again (the last time it was lower than $350)
Hawaii is one of the states that the Hawaii's Division of Financial Institutions, "determined that licensees who hold virtual currency on behalf of customers must maintain redundant fiat currency reserves in an amount equal to the aggregate face value of all digital currency funds held on behalf of customers".
This translates to CoinBase to hold cash reserves (or equivalent assets) in order to do digital current business in Hawaii. The fiat money is same as the redundant collateral.
Coinbase of course does not want to commit to this and therefore they cannot do business with a Hawaii resident. They are therefore OUT.
