Obviously, virtual bitcoin does not deteriorate, it is convenient to store and transmit. All actions with bitcoins are recorded on a whole network of computers, which protects the system from hacking or falling of the central node. To transfer bitcoin to another user, intermediaries are not needed, even if the recipient is in another country. Bitcoins are not created by the printing house - their essence has already been described by the original algorithm, so no one can influence their release.
