I spend a lot of time analyzing the different privacy methods that currently exist in bitcoin, including Monero as a privacy tool. There is nothing that convinces me 100%, they all have counterparts. All of these include: - Lightning network - Liquid network - Swaps - Coinjoins - eCash - Statechains - Monero swaps - combination of the above. It is not that they are not effective but they have trade-offs such as: - some have little protection from a state actor. - expensive - complicated for the average user - Some are unusable for the plebs in high rate environments
