BitSilver token (BTS) is an asset-backed token where one token represents one gram of silver, which is stored in specialized vault facilities. Anyone who owns BTS has ownership rights to the silver in storage. Because BTS represents physical silver, its value is directly tied to the real-time market value of physical silver. BTS gives customers the benefits of actual physical ownership of a specific piece of silver with the speed and mobility of a digital asset. BTS can also be traded. BTS can also be used on other crypto asset exchanges, wallets, lending platforms, and elsewhere in the crypto ecosystem. BTS holders can look up the serial number of their stored silver at any time by simply entering their WONPAY wallet address in the BTS lookup tool.
