In addition to providing enhanced security and convenience when it comes to making payments, cryptocurrencies also have some unique features not found in other forms of payment methods: for instance, most cryptos offer anonymity since only account numbers are visible during a transaction rather than personal details like names and addresses; many cryptos also come with built-in smart contracts which enable automatic execution based on pre-defined conditions; finally, certain tokens even allow users to back their currency using commodities like gold – allowing investors more control over their investments while creating greater liquidity within markets.
