Dad: Son, where do you store your Bitcoin?

Son: Hi Dad,

I store my bitcoin on the blockchain.

Everyone running a node takes care of it.

I use my hardware wallet to control it.

If I want to move it, I broadcast a signed transaction, pay the fee, and a miner packs it into a block for redistribution.

Then, either I as the remaining owner or the new owner, can control the newly created bitcoin output onward.

Dad: If they don't lose their keys.
