11. Cryptocurrency – Privacy

Because all Bitcoins transactions are visible, one of the ways it is proofed against fraud and manipulation, you need to take some effort to protect your privacy with Bitcoin. Because all transactions are stored publicly on the network, they show the cyber address, generated by your wallet and the balance of your Bitcoin account. The cyber address does not give away your real address until the purchase take place and even then, only to the other party in the transaction, not to anyone else on line. However anyone obtaining this address can see all the transaction related to that address. For this reason you should only use a Bitcoin address only once.

To protect your privacy, you should use a new Bitcoin address each time you receive a new payment. Additionally, you can use multiple wallets for different purposes. Doing so allows you to isolate each of your transactions in such a way that it is not possible to associate them all together. People who send you money cannot see what other Bitcoin addresses you own and what you do with them. This is probably the most important advice you should keep in mind.

Publishing a Bitcoin address on any public space such as a website or social network is not a good idea when it comes to privacy. If you choose to do so, always remember that if you move any funds with this address to one of your other addresses, they too will be publicly tainted by the history of your public address. Additionally, you might also want to be careful not to publish information about your transactions and purchases that could allow someone to identify your Bitcoin addresses.

Because Bitcoin operates on a peer to peer network, you IP address can be read with any transaction. There are ways to trace an IP address back to a physical address, so it’s a good idea to conceal your IP address with a program like Tor ( http://www.torproject.org ).

Another method of concealing your identity is using a mixing service. This is a deceptive and misleading method that is considered as akin to tax evasion in some countries. Also the mixing organisation has all your information, so you need to trust them and hope they have sufficient cyber security in force.
