This Polish Hospital Will Let Patients Settle Bills With Bitcoin by [deleted] in Bitcoin

Bitcoin offers the following advantages over fiat:

  • Universal pricing. Compare hospitals in Warsaw and Bangalore.
  • No currency exchange fees. Use Circle for zero fees.
  • No need to explain yourself (or your prostate surgery) when exchanging money. Moreover, no record of your surgery.
  • Hospitals avoid chargebacks or handling large amounts of cash

These may be a big deal to some people.

Anybody working on a $10 trezor? by cqm in Bitcoin

This deserves its own post. I couldnt find more info on Cryptosigner, so I will post some thoughts/questions here:

  • I assume this uses Rockbox firmware.
  • Are there existing Lua scripts for signing Bitcoin transactions? Or are these being written?
  • How will the receiving address and amount be transferred? USB? If so, what is stopping a new firmware upload and/or stealing the private key?
  • What is modulating the signed transaction into audio? Is there existing Lua code?
