Wow this is shocking to me. How come this exchanges are so invested in this "Tether" company? Who would exchange $1 for worthless 1 Tether? How this started? I must read about this a lot i see.
Tether makes it easier for many users to invest. Lots of people who live in different countries cannot buy USD, but they can buy tether. Tether is also interesting to avoid being taxed, and you will pay taxes only when cashing out.
So those exchanges are investing in tether because having some tether helps them to get more volume and customers
