Bitcoin, the only "proven" crypto coin thus far, totally failed as a usable currency because of the high transaction costs. Other cryptocoins including BTC, Ethereum, Litecoin or whatever do not have lower transaction cost than traditional currency. In fact I would argue that since public blockchain require mining transaction costs can never be that much lower than traditional currency.
