What are the options for turning a paper Bitcoin wallet with 2 QR codes into cash at a bitcoin ATM without first moving the funds to a digital wallet?
The idea is to create a paper Bitcoin wallet, put bitcoin into it at a Bitcoin ATM, and then redeem it for cash in the future at a second Bitcoin ATM, without using an online wallet that could potentially expose my personal information. Or something like that.
Is that possible?
The problem is that this is not something you can do on the side of the paper wallet, it's something that has to be done on the side of the ATM.
I guess that it wouldn't be that difficult to add a "sweep" feature to the ATM, so it sends the money from paper wallet to the operator's address and then continue as it does now.
So I guess that all you have to do is:
1. Convince ATM producers add such a feature.
2. Make sure your printed paper wallets have a QR code with the private key.
All in all, until the moment ATMs will have such a feature (which I don't expect to be too soon, if ever) I suggest you start writing down HD seed instead of private keys. It's less prone to mistakes.
