Just buying a tether like any other stable coins makes no sense, since they alone cannot make a profit. Stable coins are created more for ease of use of cryptocurrency, so as not to withdraw our fiat cryptocurrency funds in some critical situations, and then, when the time is right, do not return these funds back to cryptocurrency. Previously, without stable coins it was quite difficult, and they make it easier for us to move from one type of cryptocurrency to another, when it is urgent to withdraw, and investing in another type is still early.
