Blockchain technology can also be readily added to existing services for one-of-a-kind token economies. Tokens issued by services made with the platform can be linked to and managed with BITMAX Wallet (which is in turn linked with LINE IDs), opening up the option of creating services that fully or partially leverage LINE's userbase.
