I have lost exactly zero dollars with the bankruptcy of FTX, I did not had money at this exchange, or any exchange for that matter, and I did not invested in their token either, now I am holding bitcoin and its price went down so you may wonder why I do not think I have lost a single dollar? But this one is easy, as long as you do not sell your coins you have not lost anything, and since I was planning to hold my coins for the long term anyway this bankruptcy has not affected me economically at all.
