i disagree. as i said, stack btc use whirlpool and spend with monero. each has it's place. btc privacy can't match monero.

If you need an external mechanism (like coinjoin) to make your coin anonymous, then your coin isn't really anonymous

Coinjoin is ownership obfuscation. It doesn't provide any privacy like Monero does. All amounts and connections are visible and more vulnerable to future mistakes or offchain data.

Expensive, slow, and tedious too
