Hello.

What i've heard is that Bitcoin transactions are public available.
Most use Blockchain and so on. How can assure most privacy, when
changing Paypal out with Bitcoin?

Transactions are only publicly available as pseudonyms called addresses.  If you use a different address to receive from each new person (which Blockchain does for you if that's what you're intending to use) then your privacy is very safe unless someone is doing some kind of full-on police work to find you.

In which cases and where is the same Bitcoin address used?

- You talk about, when recieving payments, but what about sending payments to others?

if you are trying to hide while using bitcoin and charging back paypal, let me tell you right now that is not going to work because nobody will trust you online enough to give you bitcoin (which doesn't have charge back) against your paypal (which can easily be charged back).

also it is against Paypal's ToS to use their services to buy a digital currency (aka bitcoin) and they will close your account and take your money, specially if you charge it back and the other party files a complaint with Papal, informing them of what you did.

Don't mix PayPal and bitcoin.

Not only cryptocurrency trading is against PayPal ToS but Bitcoin is irreversible payment method while PayPal money transfer can be reversed.

Blockchain is a name of the bitcoin ledger, it might be confusing for new users as it is name of known online wallet too.
Every transaction will be forever stored in the blockchain, but unless you know exactly which address belongs to whom you can't pinpoint who exactly sent/received BTC.

I don't think you understand this.
Let me break it down...

First off - I own no company, so we can already exclude "costumers".
Second off - I'm trying to make normal payments privately. Like products, services and so on.
Third and last off - If people are dumb enough to believe scams, spam and so on - everything is possible.

Just because you don't like Bitcoins, don't mean everybody does.

Use bitmixer if you are trying to send from different addresses to one final address and don't want anyone to know where those coins from those different addresses ended up.

Use bitmixer if you don't want anyone tracking you from exchanges to your wallet or vice versa.

Use bitmixer to cover your tracks between known and public addresses and exchanges as well to confuse bankers/taxation.

Now if you'd paid me $2000 I could suggest a method to successfully launder $2,000,000 by only losing $200,000 because as you might already know laundering money is very expensive.

Unless you won't disclose publicly that the address you are using is yours your all transaction will be confidential.
If you link your bitcoin address with a service which knows your ID i.e. you buy bitcoins from exchanges, then they would know that the address used is most likely yours.
Bitcoin scams are harder to stomach because if you send coins to someone by mistake, there is no way that you will ever get them back.

If you want to remain completely anonymous, you need to use bitcoin mixers or 3rd party wallets like https://bitmixer.io/ that do not have one particular address as an identification and hence your account would remain anonymous as nobody can guess where you have sent your bitcoins or from where you've received them. Your main account would be unknown and hence your identification would be anonymous. You can then send bitcoins using this mixer and cashout via PayPal.

you can exchange paypal to bitcoin in virwox and localbitcoins.com
if bitcoin exchange to paypal, coinbase in GDAX support too
without privacy bitcoin transaction still anonymous

None of my payments should have with PayPal in any way.

This is Bitcoins only. From this date.

Using paypal to trade online is a bad idea because whoever you are trading with will have at least your name and email address which is enough to find out exactly who you are and where you live. If you want privacy when dealing with bitcoins then it is necessary to change your bitcoin addresses often and to mix your coins using one of the mixing services out there such as bitmixer.io.

PayPal is excluded, if you didn't understand it, the first time.

I just want a place, where addresses are temporary. I don't need to have one alone.
That's all.

Sorry for that.  Looks like some people weren't reading the thread.

When you receive Bitcoin to your address, sending will effectively be from that address.

So if I receive 0.01 Bitcoin from three different people and then I send 0.03 Bitcoin to someone else, it will be sent from the three different addresses that I received from, at the same time.  Therefore, the closest that a person could really get to finding what that transaction was is that any of the people who sent you 0.01 Bitcoin can see that you sent 0.03 Bitcoin (they can't see what it was for or any information about it though).

If you are sending less than your total balance, then the Blockchain wallet will automatically send with as few inputs (transactions you received/addresses) as possible which makes the size of your transaction smaller thus reducing fees.  With "real" wallets which aren't online, like Electrum for example, you can choose what addresses to send from.

The payments still have to come from a Bitcoin address somewhere. Every transaction will have a sender address and a recipient address. Even though these addresses are publicly available they are still secure as every transaction has to be approved from the wallet.

Yes exactly. All the transactions are public and don't worry for your privacy noone know what transaction is yours among the millions happening every week. The public aspect of bitcoin transactions is best for proving a transparent transaction for proof for a business for example. Other then that noone can know who you are but only trwck the wallet and even then it can be very difficult.
