Monero

Monero is the leading privacy cryptocurrency, using ring signatures, stealth addresses, and confidential transactions to hide sender, receiver, and amount on every transaction by default. It launched in 2014 and has resisted multiple ASIC-mining attempts, keeping mining accessible to consumer hardware via the RandomX algorithm. XMR is used where transactional privacy is essential. It remains controversial with exchanges due to its untraceability — many platforms have delisted it under regulatory pressure.
