Monero is a cryptocurrency that offers full privacy and anonymity, allowing users to carry out transactions, swaps and payments in a completely anonymous manner. Compared to Bitcoin transactions – whose public blockchain promises privacy but not anonymity, and is in fact fully traceable (once the identity of an address is revealed, its entire transaction history is disclosed in turn) – Monero, through a cryptographic protocol using ring signatures and stealth addresses, allows the sender, recipient and amount to be completely obscured.
Anonymity is guaranteed by a system of stealth addresses that creates a sort of blockchain with unlinked blocks.
I love both bitcoin and monero. Nothing can take their place.
Xmr is for people who prefer their transactions to be anonymous compared to Bitcoin where when you make a transaction the transaction address you made is traceable.
Unlike monero it is the opposite, though the only cons of Xmr is that it is not like Bitcoin which has a wide ecosystem as far as I know. Though monero is also good in the long-term honestly speaking.
I see them as two complementary systems, each with a different origin. Bitcoin is a pure payment system – the best of its kind – whilst Monero is all about absolute privacy; and once it becomes quantum-resistant, it will truly be the best.
