"If the Dollar is so safe, why does it get stolen all the time?"
Stop linking to vox.com unironically, please, it's garbage.
bitcoin != exchanges
a bank being robbed does not make money unsafe. it makes the bank unsafe. the whole point of bitcoin was not to have these sort of things... so really it's only logical they pose a problem to the protocol. it wasn't designed with that goal. bitcoin is fine, how it's used is really bad.
The transaction rate of bitcoin can't support widespread use. A bitcoin-based economy would require most transactions to be aggregated through intermediate exchanges, which is exactly one of the primary functions of the traditional banking system.
It's safe for the hackers isn't it...
If vaults are safe then why do people get robbed?
Bitcoin has never been hacked. Exchanges have been hacked.
