About blockchain analyzes,
Everything in blockchain is public, anyone can see your balance and track you and track where from your coins came, where it went to.
Like, you brought some coins from a seller at LocalBitcoins, the analyze will start from the mined block, then the block payout into multiple miner, it gets sold, the coin is sent to buyer, buyer does something and at last it goes to you, the recipent, then the buyer then buys something.
Now it's public... We know that:
1) From which buyer you brought coins.
2) Who mined your coins.
3) Who you sent your coins.
4) For how much you sent to the bitcoin seller who sold your item..
5) What the seller will do with it.

Is that clear enough???
If not used dummy addresses, you are pwn3d by the government that way.

all bitcoin transaction are saved in blockchain.so if any authority,government want what kinds of thing they can track about user?
what types of knowledge they can find by blockchain?
can they catch someone by blockchain or BITCOIN IS ANONYMOUS?
PLEASE, I BEG YOU TO STOP CALLING BITCOIN ANONYMOUS....
Bitcoin is NOT fungible and blockchain analyzes can reveal from where did you buy to where did the bitcoin first get mined...
is government can find satoshi then they can , if not then you know what can happen.
what do you mean...your comment is just like any dialogue lol.
i ask you what is relation between satoshi and bitcoin security?
satoshi is human not network.now one thing is conformed that if someone pay attention on theirs transaction using unknown ip no one can track them.
I think he meant to say that if a person could be traced with transaction,government could have traced Satoshi also

1. you are never as anonymous as you think on the internet, everything you do you leave a fingerprint..

things like,

HWID, Browser ID, Browser Plugins PID, Firefox? Geolocate is on by default in firefox along with other nasty things.. DNS leaks,  IPv6 is a big no no..

My advice would be if you wanted to stay hidden do the following..

Dban your HHD,  

Do a clean install use truecrypt or veracrypt to create a hidden OS partition and install whonix (https://www.whonix.org) hidden operating system,
i would remove my network card from the machine and run on a stand alone usb adapter with mac changer,

I would also follow all the steps here to harden firefox and kill off any of the crazy things that are in the about:config area you will be shocked to see a browser aimed at privacy coming with things like geolocate and RC4 encryption active..
Step 3 onward is best advice!!

https://vikingvpn.com/cybersecurity-wiki/browser-security/guide-hardening-mozilla-firefox-for-privacy-and-security

make use of VPN-TOR-SOCKS5-VPS-SSH connection.
I would never connect to the internet at any location I am linked to if I wanted to stay hidden.  
Not even public wifi is safe hacked wifi is best to use if you wanted to stay hidden..

DNS leaks are also important if you needed to stay hidden.  IPleak.net  is a good starting place to test see if your dns is leaking info while you are connected to a vpn.
if it is then best get some advice..

When sending BTC I would only use a standalone wallet like electrum,  None of these online wallets are good for your privacy.

I would also use a bitmixer before and after sending coins to mask where they are going to and where the remainder are hidden.

Now, your question was could someone be tracked by block-chain.. My answer is this.. If someone did all this to hide there activity.. what are the chances of them being successfully tracked..

people get caught or get tracked when the funds are moved into the "real" finincial world into bank accounts. that's where people slip up if cashing out..



Wait wait wait what what wait what?!!!!!!
Are you on.....?

Wait, so you mean use TrueCrypt or VeraCrypt, DO YOU KNOW THAT VERACRYPT IS F***ED UP FOR LINUX-based partitions.
It somehow corrupts the ext4 partitions and destroys the superblock.
I'd recommend to use a dm-crypt or cryptsetup-based architecture along with LUKS-LVM

And are you thinking of using Firefox as a bitcoin client (web ones).
If then, you are d00med.
Use a standalone client that doesn't leak s**t about you, like Electrum.

If you are worrying about DNS leaks you should most probably garlic wrap your DNS requests in a system like OpenNIC, as we do in I2VPN, VPN is not standalone and has its bad points.
Timing attacks will be easy to find if you use VPN.

OK, so you also agree that you should use a centralized mixer?
No, you should NOT, use Joinmarket, that's a CoinJoin-based mixing service but in this case, you have to do it a lot, according to your paranoia.

A recive -> Mix -> Account -> Mix -> Coin sell, should do the trick...

Why? What is the relation? Come on, if Satoshi get caught, does that will make any sense to Bitcoin security and privacy? I think that's doesn't matter.

It depends on if you've used that address to post online with.

Consumer A buys $10 in BTC from Consumer B using a fresh address that hasn't been posted anywhere is far less likely to be discovered compared to Consumer A that uses the same address everywhere and has it posted in a bunch of places.
