> Even Monero? There are literally hundreds of cryptocurrencies. The term does not imply anonymity nor privacy, just the concept of a somewhat decentralized ledger that relies on cryptography to ensure the authenticity and integrity of transactions. In those hundreds, certainly there are different goals with different currencies. The question remains though - are those who focus on privacy and anonimity field-tested? Are there cases of demonstrable attacks on the anonymity characteristics of a given implementation that can attest for their robustness? AFAIK no, but feel free to add any independent analysis or incident I may have missed. > How does it matter if it's open-source? OpenSSL is also open-source and every year there is a new vector of bad news. Being open source in some projects - specially crypto projects - means that motivated attackers can identify potential vulnerabilities quite easier, instead of "more people will look at it, ergo it will have fewer bugs". There is a huge potential for planned defects to go unnoticed on a complex cryptography product.
