I feel that Crypto world is too new to apply regulatory terms applicable to other industries on it. While I agree that Tether team have acted amateurish earlier last year, I would like to know more details on why Friedman/Tether relationship ended. It may be that they may be applying too much parameters which are applicable to traditional industries, and Tether may not be happy with it. Time only will tell that.
Till then people are going to use Tether. I personally like it as it helps to save your profits during bearish weeks like we had in January 2018.
