I have a huge problem. Can somebody help me?
The best would be to create a new topic in the correct sub.
I send coints from my coinbase account to my binance account, and unfortunalty there was a copy/paste error and I send the coints to anoher adress/user/platform etc.
A copy/paste error can not occur.
If you have misstyped the address, the chances are very very very low that it actually is a valid address.
If copy/pasting results in a different address being pasted than you copied, chances are high you have a clipping malware.
Try copying any address and paste it into notepad (or anywhere else). If a different address appears, you computer is infected with malware.
In this case, you need to save your personal data and reinstall your OS to make sure your system is clean.
The Id-adress do not belong to binance and they can help me.
coinbase and letherscan can't help me too.
Of course they can't. Only the receipent can (voluntarily) send them back to you.
I can't believe it, that there is no way to find out, to wich user or trading platform I send the coints?
That's due to the pseudonymous nature of bitcoin.
