Bitcoin was not created to replace commercial banking, bitcoin is an alternative and we use bitcoin freely and independently. It is unlikely that bitcoin will replace commercial banks as many countries only allow the use of bitcoin as an investment asset. Bitcoin being anonymous will be much safer and that is why people simply avoid KYC, but if you use an exchange that requires KYC that means our data is also recorded on that exchange.

Most people avoid KYC, but when we use an exchange that has obtained an operating permit in our country, KYC is an important thing to do because otherwise we cannot carry out transactions. Although there are options that we can do and if we want to appear more anonymous then use an exchange that does not require KYC.
