I have been using the blockchain site since around 2014 or 2015, if I remember correctly the address was blockchain.info. After a few years, unfortunately, some bitcoins were deducted from my account for no reason. At first I thought my wallet had been hacked, but then I noticed that there was always a significant amount of satoshi left in my account, and I was sure that my account had not been hacked, because I did not share that account with anyone. I contacted the site's support and all they told me was that we do not have access to any information. But now they have access to everything, even our identities.
