I've been mindful of the ways companies can track my spending habits, and so have been increasingly keen on using cash and avoiding mobile banking/payment apps like the plague. I realize that this varies by country and might be a bit far out, but the thought does linger in the back of my mind. If current trends continue, how much longer until they take cash and browser-based banking from us? Or will there be a reason those options should continue to exist (and be easily usable) far into the future? And perhaps:

  • What else can I, as an individual, do about this?
  • Is there a tendency for larger banks or smaller credit unions to push towards mobile-only online banking?
  • What does it look like in countries where cashless and mobile payments are the norm?

Yes, in Bitcoin, they were known as Cassaceous coins.

They are physical coins with the QR code for the address to send Bitcoin to on them and the private key was hidden under a hologram. And if the hologram was scratched off, you know that the coin had been used and that it wasn't worth anything.

As long as that hologram stayed intact though, you could guarantee that the coin actually had the amount of Bitcoin that it said it did on it.

And yes, you could very well do something similar for Monero.
