Users often joke Monero is the real stable coin. Hovers around average of ~$150 for years.
Maybe you already know this, but ring signatures are only 1 of 3 of Monero's privacy layers and only apply to the sender. It is the relatively weakest part because it is "just" obfuscation.
The real magic is Monero's encrypted amounts and receivers (confidential transactions and stealth addresses). Completely hidden - can't be derived by looking at the blockchain. Meaning the transaction graph (sprawling connections of senders and receivers) doesn't even exist on Monero, unlike 99.9% of cryptos.
