Why referring to Michael Saylor? What I know about that man is that he likes to tweet much about bitcoin. Aside that, I do not notice anything. I have not seen him directly telling people not to invest on certain altcoins, but maybe I am not completely right about this. We all know that Tether is not a trustworthy company and we know some things about the coin are shady. I think JPMorgan did not just talk about this coin without no research. He researched and saw what we did saw in the past that we said tether is not reputed because of how shady they are and in connection with Bitfinix or something which owns tether.
I also was surprised by why he refers to Michael Sailor. This man is known for his love for bitcoin.
However, for Tether, it is true that a company is not trustworthy and there were a lot of doubts about the transparency and the suspicious things they did, but in the end they submitted their reports and fully subjected to government demands and regulations.
In other words, I want to say that they are acceptable to the government, but they are not worthy of us, who believe in bitcoin and decentralization. What is Tether different from JPMorgan or any other central bank? It may be worse !!
