Bitcoin was initially conceived as a way for people to exchange money anonymously. But then it was discovered that anyone could track all Bitcoin transactions and often identify the parties involved.
Bitcoin operates by giving each user a unique public key, which is a string of numbers. Users can transmit money in the form of digital bitcoins from one public key to another. This is made possible by a system that ensures a user has enough bitcoins in his or her account to make the transfer. The use of the public keys gave users a sense of anonymity, even though all of the transactions were visible on the public Bitcoin blockchain which lists all transactions. O
so it is very safe no hard at all.
