Coin that is privacy is the privacy coin. I think it is bitcoin if we talk about privacy. Btc wouldn't ask anything to one person diaries or curriculum vetai. Btc is anonymously from the beginning until now.
Are serious?

How can BTC be called private when it's traded on exchanges which can give info about their users to goverments? e.g. One of exchanges is planning to give all their users' info to US goverment. Where is privacy here?
Besides there is one very good post about privacy here:
What is The Most Privacy Coin In The World? As revolutionary as Bitcoin is, it has one major flaw privacy. Since the blockchain ledger is public, all transactions by all addresses are completely exposed. This rightly causes some feelings of insecurity. After reading this, I can hear some of you say Big deal I dont have anything to hide or I dont mind people knowing what my transactions are. I respectfully disagree Even if we have done nothing wrong, our transactions are no one elses business. What if I were to challenge you to approach the nearest stranger you can find and show him your credit card bills for the past 5 years, or to lend your phone to a colleague and tell him to browse through your emails and messages? Wouldnt you feel hesitant? Wouldnt you feel violated just because you have nothing to hide doesnt mean people or governments should be able to snoop on you. If you agree or at least can see my point, then please continue reading.
And I completely agree to it.
