This author is way behind the times. Bitcoin is obsolete. Nano (nano.org) is what the author should be looking at as the future of p2p digital currency. Nano transactions are feeless and take under 1 second, fully confirmed. If you send 1 Nano the recipient receives 1 Nano. There is no mining involved so it is green and it is decentralized. These features make microtransactions possible. You could use it to pay a fraction of a sent to stream a song or read an article. Or us it to log in to websites. Npass is doing both. https://npass.dev/npass Robocash is using Nano to prevent robocalls. https://www.myrobocash.com/

Smart contract coins like Ethereum will have tons of uses, especially for digital goods. You could easily cut escrow.com (and all escrow fees) out of the process of transferring domain names (and other digital goods) with smart contracts if a domain registrar got with the times.
