As stated on HTDC's DCIL section:
"Uphold HQ, Inc. is a digital money platform serving more than 7 million customers in more than 150 countries. Uphold today holds around $2.5 billion in customer assets. The Silicon Valley firm opens around 16,000 accounts a day typically as consumers seek a more versatile and cost-effective home for their financial lives. Leveraging blockchain technology, the platform provides both consumers and businesses with easy access to 51 digital assets, 28 national currencies, four precious metals and 50 fractional U.S. equities. Not all assets are available in all regions. Uphold’s unique trading experience - ‘Anything-to-Anything’ - allows customers to trade directly between asset classes, saving time and money. Uphold supports financial inclusion by enabling customers virtually anywhere to open an account in less than 5 minutes and invest with no minimum amounts. Customers can send money to virtually anyone with an email address free of charge."
Conclusion: This platform seems to have it all. I have tried to open an account with Uphold but still no luck. I have read online they do not yet operate in Hawaii. I have also reached out to customer service who very politely reassured me they do not yet operate in the state of Hawaii. This is too bad and their products and services seem very appealing. Offering their customers more to trade than only cryptocurrencies among other great services.
