Please Help! BTC is suddenly zero at blockchain, still seeing it in electrum

[WNTD]

Hello,

I have an electrum wallet and everything is okay there, I still see my coins.

But here [removed]
it shows that they have been moved out today at 09:11 together with another transaction which I made at the same time.

How is that possible? I restarted electrum and everything is okay there, but as you can see, on blockchain.info it shows that my balance is zero and everthing has been moved out to an other address.

Please help, thank you.


EDIT:

As you can see, the coins have been moved to here [removed]
I just sent a test payment, It seems like it works? How can it be, that this [removed] is now my current address?

EDIT2: Together with the payment, the coins have been moved again to another address: [removed]

How??

Every time you make transaction in Electrum wallet is create "change address" and on that address is change what left when you send BTC.Let's say you have 0.2 BTC on some address and want to send 0.1 BTC,wallet use total amount from that address in a way that send 0.1 to address you chose and other 0.1 minus fee is allocated to that change address you see.

This is very good for your privacy because on this way it is hard to somebody to know how much BTC you have and where you send them.There is option to disable using of change address in Preferences/Transaction,but it is recommended to not disable this option just because of user privacy.

I see, thank you.

The disadvantage is that I pay the fee for every re-allocation, right? For one allocation this may not be much, but it sums up, what do you think?

Thank you for your time.

EDIT: If someone follows the trace in the explorer, he can see where it went and so he can see how much I have anyways, right?

Not with change address.

Imagine this scenario. You are paying address A and you generate a transaction using Electrum.

Electrum creates a transaction with the following as output:
Address A - 0.2BTC
Address B(change address) - 0.3BTC.

Anyone who sees the transaction won't know how much the sender has since they have no way to know whether the sender controls either of the address. Of course they can estimate, but with very low certainty as opposed to sending the change to yourself.

Suggest you might like to read this entry regarding "change": https://en.bitcoin.it/wiki/Change

and also this one, it explains why change happens... and why you can't just send "exact" amounts of BTC in a transaction: https://en.bitcoin.it/wiki/Coin_analogy

The disadvantage is that I pay the fee for every re-allocation, right? For one allocation this may not be much, but it sums up, what do you think?

No... you don't pay a fee for every "re-allocation"... you pay a fee "per transacion". Because you're sending the transaction anyway, the overhead for including the "change" output is only 34 bytes... which doesn't really alter the transaction fee by that much in the grand scheme of things.

Worst case is moving from a 192 byte transaction (1 input + 1 output) to a 226 byte (1 input + 2 output) transaction... that would increase the fee by around 18%... but if you have any more inputs or outputs, and that percentage drops pretty quickly.
