No, bitcoins payments are not anonymous. The blockchain stores every transaction including sender and receiver. However, bitcoins payment is pseudonymous: The blockchain does not know any private data, but only signatures and addresses. Bitcoin thus allows a degree of privacy that goes far beyond that of banks and payment service providers.

If you store your private key securely, no one can confiscate your bitcoins.  Only the one who has the key can access bitcoins. It is protected by strong cryptography.

If you make the transaction yourself - no. Transactions are pseudonymised and processed by a network without distinction. As Bitcoin is a decentralised network, there is no central location with the power to prevent other nodes from carrying out and verifying transactions - as long as these are covered and valid according to the rules of the network. 

As all transactions are transparent, it is important to look after your privacy. Most wallets automatically have a few fundamental rules in place. You will never use the same address to receive Bitcoin, including change. Where users use multiple wallets, this significantly increases your privacy.  It is also good for privacy to use offchain methods such as lightning or BitBucks. 

Usually the Bitcoin wallet keeps your private keys private by storing them in an encrypted file. You can also print the private keys as "Cold Wallet" and separate them from the Internet. You should be aware that you are solely responsible for the security of the keys. If you lose them, you lose your bitcoins. Wallets such as BitBucks, which store keys for their customers, can offer inexperienced users additional protection against key loss.

In almost all countries, the use of Bitcoin to send and receive money is permitted. In a few countries this is restricted or completely forbidden. Please seek reliable information as to the legal situation regarding Bitcoin in your country.

A Bitcoin wallet is software you can use to administer your bitcoins. There are many wallets for all common computer systems. You can choose between local and online wallets. A local wallet gives greater independence and privacy, while an online wallet can offer more convenience. 

Anyone who has access to the Internet. Everyone is equal with Bitcoin; the network does not require permission. Age, gender, religion, social status, origin - Bitcoin does not recognise these categories.
