Dear Manuel,

thank you for reaching out.

According to our logs your withdrawal has been successfully processed, as you may see in the "Transactions" section of your account under the following link: https://www.bitstamp.net/account/transactions/

You should also be able to view your withdrawal on Ethereum blockchain under the following link: https://etherscan.io/tx/0xc5178537220d4960adaac0cee32c7b81895e52e20e70c0af86f2d22f73fa400a

If that is not the case, I kindly suggest you contact the receiving address provider as they should be able to assist you further.

Should you have any other questions, feel free to ask.

Best regards,
Andreja Kržišnik

The problem is that Yobit is a SCAM and not give me a answer.
Beware my friends.
