Anonymity of Bitcoin
If you think Bitcoin is an anonymous cryptocurrency… you are totally wrong. Despite the high level of anonymity of Bitcoin, you should understand that thanks to the blockchain technology, the use of crypto currency is also fairly transparent. Knowing where you expect the payment, or from which address you make it, outsiders can easily track the movement of your funds.
Many e-currency exchange points and crypto-exchange exchanges often require the verification of your identity, which will ultimately make your personal data public in varying degrees. Some people using Bitcoin are looking to get a real privacy and this is where bitcoin mixing service websites are useful.
What is Bitcoin Mixing?
Bitcoin tumbling, also referred to as Bitcoin mixing or Bitcoin laundering, is the process of using a third party service to break the connection between a Bitcoin sending address and the receiving address(es).
In other words, coin mixing services take your cash and give you new cash to your secret identity so that it remains secret.
Conclusions
It’s important that they be trusted. There’s no authority or government you can complain to if they run off with your coins. So if you like privacy and also want to protect your cryptocurrency from government tracking or tracing, Bitcoin mixer services are a good option.
