Nobody truly owns any bitcoins..because the ownership is only established when you are able to apply a correct private key in a "send" tx (via hardware device or something else), albeit validation of the private key (at some other point in time) is possible. Before that, it is all allegedly. This is in principle, of course.
Nonsense. Of course you own your bitcoins as long as you and you alone possess the private keys to your Bitcoin addresses.
No hardware devices are required other than mnemonic devices. It's the corollary to NYKNYC...
your keys, your coins. No one can take them away from you, no banks, no governments.
Contrast that to less finite asset ownership such as fiat currencies, "precious" metals, real estate, art, antiques, etc.
The only assets as valuable as Bitcoin are the relationships you establish with people.
