Doing it wrong, the point of crypto was to liberate you from 3rd parties.
Its also not exactly improving anything on an efficient and stable financial system.
If you live in a place, or trade with a place that doesn't have a good system, then you might have a reason to use crypto, but be responsible for your own wallet.
If you feel like your stable system might turn on you, it might be wise to have your own wallet and hide it someplace just in case.
I expect the killer app moment will be when nations or nation level entities realize they can conduct trade without the permission of the US.
