A [significant bug was discovered in Monero's privacy algorithm](https://decrypt.co/76938/monero-developers-disclose-significant-bug-privacy-algorithm?utm_source=telegram&utm_medium=social&utm_campaign=smt)

​

This outlines two huge problems with monero:

​

1. It may not be as "private" as one first assumes, and there many be advanced ways to track the movement of funds.
2. Despite having been around for over 7 years, there are still bugs within the code.

This brings us to question whether the inherent nature of privacy coins is extremely risky.

​

If the blockchain is not transparent, how do we catch foul play? How can we be sure that there was no brilliant hacker who managed to exploit something within the code to mint an infinite number of XMR coins for himself?

​

How can we be know that there aren't other bugs being exploited as we speak, if we can't easily see any data regarding ownership and transactions?
