Many people wonder whether Bitcoin is anonymous or not. Blockchain technology is a publicly accessible database that allows anyone to track all transactions ever made at any time. However, the respective addresses consist only of numbers and letters, they are alphanumeric. With a little analytical skill or the necessary basic technical knowledge, it is then possible to actually trace who has sent how many Bitcoins to whom.

Finally, there are also crypto-currencies, so-called Privacy Coins, which offer a certain anonymity quasi “by default”. One of the best known is probably Monero. There the ring signatures ensure that the traces are gradually erased. A system similar to the Bitcoin mixers.
