If it were true, then definitely it is a bothering and worrying news. I am going to great length to make sure I transact crypto anonymously (including using public networks as IP providers) but I am sure I make mistake here and there (I am even aware of some information leaks I did in the past) and I would hate to know that some agency is puting that information together to try and deanonymise me... I am quite sure that in spite of all my efforts, eventually they would be successful.
Feel free not to answer, but out of curiosity, why do you feel the need to go to such great lengths about covering your tracks?
I have to assume it's not necessarily related to illegal activities, but what difference does it make if (hypothetically), there is 'visibility' over you using Crypto X, y or Z to purchase a Steam game?
