- you can use an escrow account to reverse the transaction if needed - having full ownership of your money and it being censorship resistant (depending on the crypto) is certainly a plus if you don't fully trust your government. - the conversion to fiat is depending on adoption: the more adoption there is, the less necessary that would be. - you can decide to wire your money 24/7, internationally, instantly and with no fees (with the right crypto)

Overall you get more control of your money. If you think of money as just another kind of information, it's normal to expect it to evolve in the digital age we are living in.
