That's great but most people aren't going to buy $100 of Bitcoin(and pay a 5-10% fee) just to buy something on Amazon. purse.io is for holders and that means exposure to RISK
This is starting to feel like an ABC talking point. I think I bought exactly one thing on Amazon this year. That's not enough txns to pay miners when the block reward halves.
I have bought a lot of stuff and saved a lot of money. It's a current talking point to get people using it. How many times can you talk about "Adoption is key"? That's obvious.
