A good read.
In these difficult times, lateral Bitcoins, brrrr and CoronaVirus scare, nothing better than a nice read from my fellow italian Bitcoiner @giacomozucco about Bitcoin Privacy.
Two part article.
I bet you have time in your quarantine:
A Treatise On Bitcoin And Privacy Part 1: A Match Made In The Whitepaper
Introduction
How one’s focus can shift in just two weeks! While today everybody in the Bitcoin space seems more concerned with price fluctuations in response to the global financial panic (understandably so), it’s important to remember perennial issues that never go away, like the importance of maintaining your privacy when you transact in bitcoin. Throughout this month especially, we’ve been hearing reports of KYC/AML-compliant exchanges freezing user accounts due to suspected use of CoinJoin software (more on that later), followed by yet another case of a famous and respected early Bitcoin proponent promoting his new illiquid altcoin as something that “will replace Bitcoin, which isn’t private enough!”
If you want to take a short break from global pandemics, financial meltdowns and price volatility, here’s an attempt at analyzing claims, facts and context of this latest “Bitcoin drama.” To begin with, in Part 1 of this two-part series, we’ll start by looking at the fundamental relationship between Bitcoin and privacy by going back to the beginning with the whitepaper. Then, in Part 2, we’ll focus on some the ways that Bitcoin privacy is being maintained and improved upon — and strike down a few “red herrings.”

Bitcoin is an effective system to transfer and store wealth, but that wealth has first to “enter” the system somehow, very often coming from fiat money. (Of course, you can also earn satoshis directly in exchange for goods and services you provide, instead of buying them with fiat.)
Fiat-enabled bitcoin on-ramps (often known as “cryptocurrency exchanges”), acting as liquidity bridges, created huge privacy problems in Bitcoin. In order to manage fiat, exchanges will have to use traditional bank accounts. In order to get those, they have to meekly accept all the rules, conditions and limitations banks require. Traditional fiat banks, in turn, will pass over the extremely complex and heavy “compliance” burden they received from governments and regulatory agencies, including that concentration of economic illiteracy called “KYC/AML regulation.”
So, fiat-to-bitcoin bridges will almost always end up demanding a scary amount of personal information from their user, linking that information to a few deposit and withdrawal addresses (often incentivizing continuous reuse) and then even hiring “chain-analysis” companies in order to follow, trace, tail and stalk all the previous and following economic activity on-chain.
