I think everything is clear now. The only thing I do not see the differences in the functioning of the same coin, which works as a replacement for the dollar. Such a coin is called USDT on many exchanges. If so, that is good.
A big difference between Constant and USDT is that we regularly publish independent audits of our USD reserves. You can also see how many Constant have been created on our smart contract. Being able to do both of these things means you can always check we're matching Constant to USD.
