Theres a big misconception that bitcoin is entirely anonymous. Bitcoin is pseudoanonymous, in the sense that your name is not linked to your bitcoin address, but you still have a bitcoin address thats static and so it could technically be linked to you.

Is this a True ?
The bitcoin transactions were anonymous until you reveal your bitcoin address or wallet ID to someone but it is definitely more secured and private than the fiat transaction because banks were doing transaction for us so they have all our details and can use it without our permission too so in that case bitcoin is pretty good invention and also you can increase the anonymity of bitcoin transactions by using coin mixers.
Well as long as you are the only one who has access on your own account then the transaction will still be anonymous. Actually we can't really say bitcoin is anonymous especially when some of your friends knows that you own some of it. Technically it is anonymous but we can't justify that it is really is.
