Is crypto currency really anonymous?

i also heared that none of the transactions are completele annonymous but relly don't know for sure

As far as im concernd nothing is completly anonymous
+++ also interested in this following for more info

I would not say that it is 100 percent, but it has its own part of reliability

Cryptocurrency like bitcoin is not anonymous, you can see all transactions in the blockchain
If you want to be anonymous use monero.

The police can see transactions but cant tell whose wallet is whose. If you dont link your identity to your bitcoin wallet in any way(hard), police wont be able to track you.

100% Always Anonymous, and transactions and withdraws are too, as they say that bitcoin is a untraceable virtual currency.

The transactions are public, but it is not known who is behind them.

As of recently i read somewhere that there's malicious hackers successfully reverse engineering some btc addresses, which will probably make the use of btc obselete in the future sadly.

Yes but no, its an complicated question because as long as you do not post your wallet anywhere it is not traceable back to you.

But I would suggest talking with your wallet provider

Yes it is, unless you are registering yourself on coinbase or similar services.
You are going to verify your identity upon registration to buy & sell crypto
