Arguably the top 3 exchanges by volume Binance, Okex and Huobi has shared hands to other partners for issuance of another stable coin named Terra.
Tether, a token fixed to dollar by an exchange Bitfinex gained a wide popularity, which even is the most popular stable coin in most of exchanges.
Terra would not only be limited to exchanges but also would be a token for payment transactions for goods and services.
That will be a very good move by these giant exchanges, we need such a stable coin with true transparency to power so many online shops for the sale and purchase of goods and services, other volatile currency cannot serve that purpose.
