Many consider Bitcoin to be an absolutely anonymous coin that leaves no traces.
The statement is partially true: if you try and associate the address in the blockchain with a real person, all his transactions will be clearly visible. This can not be done with all cryptocurrencies.
Bitcoin and its ability to disclose its owners is not news.
Recently, crypto enthusiast and famous cryptocommunity participant Andres Antonopoulos called the first cryptocurrency “pseudo-anonymous”. According to him, it is possible to keep your identity secret for some time, but for this you will have to make a ton of effort. In general, Bitcoin is "not the best thing for anonymity."
