The whole Coldcard Issue (which I don´t have) made me think of the following:
- How can you make your own entropy? What is the most secure way?
Hardware wallets and passphrase are still the most recommendend way. - Have you declared or not your btc stack with your local country tax authority?
If yes, moving to a Exchange is an option, if not, it is not. - Buying and selling bitcoin will depend on the point above and is even difficult.
Doing non KYC is also getting difficult as I was told. - A common deslike, is the fact that all transactions are tracked back to the real ammount in the address.
i.e paying 0.00001 btc leads to the receiver to know you have i.e. 1 BTC.
How many layers of stacks do you have to have to avoid this issue?
What is the limit for Lighnting Network? Where to send it? - Inheritance: the idea of passing away and losing all is still at the table.
If you trust your couple and one of both dies then the other has still the key, but if both dies?
Banks/Justice solve this issue by giving the money to your inheritance (or keep it till they are big enough).
These are the basics questions any non bitcoiner will ask before moving into bitcoin.
