• Healthcare and medical records
• Academic certificates
• Music
• Cloud storage
• Car leasing rentals
• Ride sharing
• Property
• Apartment rentals
• Travel Industry
• Loyalty reward programs
• Prdictions and gambling
• Smart contracts
Not with Bitcoin but the blockchain as you noted in your quote.
Those possible uses above are from the book
Blockchain: Ultimate guide to understanding blockchain, bitcoin, cryptocurrencies, smart contracts and the future of money.
$3.00 on Kindle. Buy it. It's good. Certainly worth $3.
It’s a bit outdated now at a year and a third old but still very helpful in describing the technology and issues surrounding it’s use and possible uses.
From page 10.
“Billions of people in the world live in countries where they can’t trust intermediaries such as banks, governments, and legal systems for transactions or accurate record keeping. Blockchains are particularly useful in these cases to help provide trust and assurance to people when transacting with each other.”
It’s not just the book “Blockchains” that also see an opportunity to

Now, having a general understanding of cryptos and their potential uses, I’m pondering how rural people here in the Philippines might cut their middle men out completely or in part by using them.
Maybe not “all in” today but it appears to be an opportunity for a grower to deal directly with a seller. The middle men here in the Philippines often get more than either the seller or the grower for products.
Most of their utility is in the delivery and payment between the two parties.

As legal tender, you’re right. But what about other legal useful possibilities? Maybe.
