Transaction clustering algorithms render a lot of mixer services useless.
Bitcoin was not designed to be private; if people want  private transactions then they should use a fungible cryptocurrency

No one says Bitcoin is anonymous since it's only pseudonymous. User need some effort and being careful to stay anonymous while reckless action will do the opposite.
I think people shouldn't worry too much as long as their Bitcoin never touch exchanges or non-anonymous services. Mixer service should be good enough for regular person if they sure their internet activity and Bitcoin transaction is secured.

But if people have serious concern about their financial privacy and anonymity, they should use fungible/private cryptocurrency such as Monero or Zcash which offer true frangibility (sender/receiver/amount are hidden), run full nodes and use secure connection.


That's why altcoin exist. Even if technology such as Zn-STARKs, CT Ring, Bulletproof or even Turing-complete Smart Contract can be implemented on Bitcoin (and assuming majority community agree), this idea will sacrifice Bitcoin decentralization/scaling and make development/implementation time slower.
Those coins choose functionality/anonymity over decentralization/easy scaling while Bitcoin focus on decentralization/easier scaling.

I was just thinking if we really have financial privacy with Bitcoin with all these different types of analysis tools?

https://www.walletexplorer.com/ identifies your wallet provider and https://www.chainalysis.com/ link them all together. I am not sure if these analysis tools are rendered void by the use of Mixer services, but it is still a problem for many people not using these Mixer services.

My main concern is IF we have given governments the perfect solution with Bitcoin to track all financial transactions. Something that is not currently possible with Fiat cash. I am not concerned about governments that are using this technology to track criminals or terrorists, but rather those governments that wants to use that information to get rid of their opposition. <People who donate money to sites like WikiLeaks>

These tools can be used for "Good" and "Bad" and we will never know if "Bad" people are using these tools to target "Good" people. 

What is your opinion about this?

I tried walletexplorer on multiple address generated by different providers/warez and it couldn't identify the right one. So, I don't think that we really have to worry about tools like these. My advice, don't trade-in privacy for comfort, software wallets like Electrum can't compare to web-wallets that save your private keys and details on their servers.

Not everybody has financial privacy and anonymity, according to https://en.wikipedia.org/wiki/Legality_of_bitcoin_by_country_or_territory. It shows that there are a handful of countries that forbid their citizens from using Bitcoin and therefore can punish them if they do.

Everything has pros and cons, meaning that it can be used for the good or the bad. For example, you could graduate in psychology and help people or you could use your knowledge to manipulate people.

I see a lot of the staff of Walletexplorer moved over to Chainalysis, so I do not know if the project was abandoned, but I still added it to the discussion to show people what can be done. It is also more difficult to get your hands on Chainalysis, so I might not have been able to substantiate my point, if I could not use a working example of what can be done.

It is not to say, if Walletexplorer <outdated> could not link these sites, that Chainalysis < A commercial version > would not have more updated links/info to do much deeper analysis of those addresses. From the presentations that I have seen, Chainalysis is MUCH better.
