I agree that Monero's blockchain, like Bitcoin, is a giant lead weight, and Monero puts more numbers and letters into its blockchain.

I do not subscribe to the idea that XMR is going to replace Bitcoin, I think we're well past that at this point.

But the truth is the truth, and Monero is still the king of privacy. And until liquid gets significant traffic and adds several more of Monero's features, we don't have anything that's even close.

Lightning probably has great privacy but the attack vectors have barely been explored and it's not built for privacy in the first place and many ways that it's used privacy is completely eliminated. The vast majority of regular everyday users are using it custodially, which is definitely eliminating any privacy gains that it makes.

ECASH, the Chaumian types have great privacy too, but there are vulnerabilities there as well.
