Cryptocurrency being used as a real currency to do purchase

Would you be interested in TokenChat?

TokenChat is a Japanese initiative that believes in the concept of cryptocurrencies truly being a form of money, rather than a digital version of gold or gems. TokenChat does it by creating a consumer demand, enabling cryptos to be used in everyday life and stabilizing price fluctuations.

TokenChat is primarily a messaging application that enables two or more people to connect in many different ways. The chat enabled wallet application is built on the blockchain technology and is designed to connect financial services such as payments and purchases to applicable and supported cryptocurrencies.
The instant messenger, like all messenger, allows for instant sending of text, audio and video messages either in individual communication or in groups. Along with these, the following functions are also available:

•   Money transfer: Since the instant messenger is an additional layer over TokenChat wallet, users of the messenger can send and receive cryptocurrencies with their friends easily. All users have to do is select the send option in a chat, input the amount of crypto to be sent and click away! That’s easy and so simple.

•   Erasable Messages: Blockchain and decentralization is all about privacy. Keeping this in mind, TokenChat has an erasable message option. This allows users to set a defined time limit of messages to be displayed to the sender. After that, the messages will be deleted, from both sender, receiver and the blockchain ledger.

•   End-to-End Encryption: The public blockchain is all about transparency, but that doesn’t mean your conversation is available to all. TokenChat uses a unique two-stage encryption to ensure your messages are safe from prying eyes.

•   Encrypted and Decentralized Data Storage: TokenChat encrypts and stores data separately in different nodes throughout its network. This means that the data cannot be decrypted by hackers as each data piece will have its own encryption. This also adds a redundancy as even if data from several nodes is completely wiped, the original data can be rebuilt from the data on the remaining nodes.
