How private are Bitcoin transactions, really?

Hey everyone, I’m a newbie to Bitcoin and finding it a bit confusing when it comes to privacy. Can someone break it down for me? Is it as traceable as regular bank transactions or does it give you more privacy like cash? I’m curious if normal activities like buying, holding, and sending can be tracked back to me easily. Also, does it really make a difference if I use new addresses every time? In general, just how private is Bitcoin for day-to-day stuff? Sorry if my English isn’t great. I’m not up to anything shady; I just genuinely want to understand how it all works.

It depends who you're hiding from. If it's law enforcement then you're very trackable. For the average user, no so much. You're also trackable in the sense that one could figure out where did the funds go, and not necessarily get your IP address or your identity unless of course the funds did end up in a KYCed exchange for example. Obviously though, the use of mixers, jumping through multiple non kyc exchanges, swapping for with other coins, make it  more difficult.

Ok thanks alot i really appreciate but please what is a mixer

Bitcoin is a public ledger. Each address is anonymous by default (unless you publish online) for the rest there are several ways to "hide" or at least to try to keep as hard as possible to understand what happens to these funds. Yes. Every transaction should be completed with a "single use" address to improve privacy. For sure has been really "private" in most of the cases, moreover if not involved in some criminal case. There are thousands of transactions, why on the specific some one should look in a certain one? Of course most of the countries are trying in all the way to track coins from CEX ... so yes in this case the privacy could be definetely over or just you pay more taxex for your coins once exchanged in FIAT. edit: mixer are banned as service in this forum. I suggest just to have a look on google and here on the forum before making the question.

It's also a bit how you spend / receive BTC Working up through the posters in this thread. I send some BTC to bitbollo who sends it to OmegaStarScream who sends it to you. It's all very traceable, it's out there in the public ledger. The addresses and the amounts. Who controls those addresses is more difficult, but not impossible specifically if you or anyone spent any of the BTC at a place that does kyc. BUT if you then just send it on to someone else, and this is the important part, without ever having any of the coins from that transaction that came from anyplace or anyone that has any kind of KYC going on it's difficult to really track. Not impossible, just difficult. There are ways to make it more difficult, but as I have and others have said a bunch of times governments have all the time and money in the world to track you down if they want to. Also, followed up by, minor things that you don't think about can trip you up. Search for your BTC address on a public block explorer from your home, if they keep logs and get a subpoena asking did anyone search for this address and if they did what IP did they do it from and well if you are the only person who did and they are already looking at you for something. It's all they need to really start climbing up your ass. -Dave

It does helps to be anonymous but for privacy it’s actually Improbable. Then how you actually handle each address for every new transaction is also going to actually determine the anonymity. For example for privacy or should I say total anonymity you might need to actually run your own full node or at least use Tor/VPN to actually hide your IP when connecting to a public server because the node owner could dictate that the addresses are actually coming from one point of IP which will easily signifies that the addresses are from one person. Run your own full node, Use new address for new transaction, Never have any of the address get linked to any KYCed platform,  If you can actually do this for daily transactions then you can actually be anonymous but not totally private because transactions are still publicly recorded

In terms of privacy, you should not think of it like cash, because in contrast with cash, bitcoin transactions are publicly accessible forever. It depends on a lot of things. How do you buy & sell bitcoin? If you practice self-custody, do you also practice coin control or do you consolidate your inputs without any second thoughts? Consolidation reveals that all these inputs were owned by the same person. It does help, but you should also use coin control. These two are often not enough. You might have to use coinjoin (e.g., Wasabi Wallet) to break the link between your inputs.

Mixers are platforms that offers cryptocurrency mixing services. Also, as a newbie, be informed that mixers are restricted in the forum at the moment. I urge you to read about theymos definition of what the forum assumes a mixer to be. Here's your link https://bitcointalk.org/index.php?topic=5476162.msg63251188#msg63251188

Your English isn't quite bad to begin with, it clearly explains your confusion which I believe is just jumbled information you have on the subject of Bitcoin and privacy. As long as you register with a KYC on an exchange platform, your transactions can be traced that's why many exchanges demand KYC and IDs, also because your transactions get recorded on the public ledger known as the Blockchain which is the system on which Bitcoin exist. You can use a multi-sig wallet or generate a new add for every transactions as a possibility by many modern exchange apps, but somehow, sending coin to and fro your wallet to other exchange can help authorities pinpoint your ID.

On a p2p transaction No it’s not traceable because transactions are done between address that aren’t carrying any information of the user, but when linked with a CEX that requires KYC then it may be traceable.

Do not confuse the OP, you are not really correct. Theymos only gave that definition to let people understand what he sees as a mixer, but generally mixers are beyond what was banned on this forum. The first mixers are the coinjoin which you can make use of on a noncustodial wallet. The second one is the centralized mixers which Theymos was referring to and banned on this forum The third are the decentralized or non KYC exchanges that support the use of Tor, in a way that you can swap bitcoin to coins like monero and swap it back to bitcoin. The first and the third are not banned on this forum, only the second one is banned.

I can know the amount sent and where it's send and how much fees used and how many confirmation and I have no way of linking that details with the real identity of a person but if you are hiding from government then they can track those details if you used KYC to buy that bitcoin.

Using the word "mix" to define what a mixer is could get the newbie more confused than he could have already been. It's easier to just say mixers are services that offer users increased privacy in exchange for them paying a little fee for that offer. You give in your bitcoin or whatever coin the mixing service accepts and get another in a separate address, which won't be linked to where it was sent from before, but you have to pay a certain amount of fee to the service provider for their service.

Bitcoin is a public blockchain, so depending on how much data you make available will affect how much privacy you lose. Not using the same address repeatedly, not consolidating too many inputs, and avoiding KYC can go a long way in helping maintain privacy. You can take it a step further with coinjoins.

funny enough I didn't see where you made any clear definition of what a mixer means to you for the most part you only buttressed on what's already said. But still didn't answer to the op what a mixer is in clear meaning. Perhaps I didn't break it down in the simple terms for a newbie to be easily grabbed as you had done because I had thought that from there he could do his own personal research which would be much self helping than just getting spoonfed completely.

Mixers are pointless if you ignore coin control. Seen it a hundred times. guys buy p2p to stay off radar. next week they send a random tx. their wallet auto-selects inputs and grabs a tiny piece of old kyc dust to pay the miner fee. Clean coins + kyc dust = your cluster is permanently linked on-chain. Never trust wallet auto-selection. pick inputs manually or consider your stash doxed.

You don't need to worry too much about traceability if you are doing nothing really bad for bitcoins, unless you fear being a target of bad actors who could be monitoring your bitcoin activities for the wrong reasons. So, what you could do in this case is to avoid re-using a Bitcoin address for recieving bitcoins. However, this doesn't reallly help people who try to recieve stolen bitcoins, sell dangerous or really evil things that are on the red list of law enforcers... for example, things that hurt people or society. A victim or owner of the stolen bitcoin could report a thief, attacker or scammer's address regardless of whether the address is reused or not.  If the address is actually owned by attacker/thief, it could be tagged, blacklisted and monitored. The other one is selling bad things or receiving payment for bad things that could easily get you reported or tracked because your buyers probably got arrested and expose your addresses regardless of whether they are non reused addresses. The bitcoins in the addressess could be seized by the next receivers, or the owner could be captured once he tries to sell it for fiat or pay for something physically. And in regards to Bitcoin traceability vs things like physical fiat currencies or bank notes, I think they are almost thesame thing. Physical fiat currencies have numbers on them that can be tracked or traced to their first receivers/owners when they withdrew them from banks or ATMs. If law enforcers, for example, find a physical fiat, that is probably a proceeds of crime, in a house of a thief or evil person, they could find and question the person (first receiver) who first withdrew it from ATM  to know who he paid the money to, and if the money got to a second, third and even fourth receivers before getting to the thief, they(the subsequent recievers) could be traced and question aswell, as one or more maybe connected to the thief. That is it basically. If you are doing nothing really evil for bitcoins, even though evil is evil, you don't need to worry too much as no one will spend too much time trying to trace an innocent person coins unless maybe you are into activism or things like that, then not reusing addresses becomes very helpful for people like you. They won't have any reason to tag the addresses or seize the coins from them
