Re: [Group Buy] AVALON CHIPs 5022 left @0.082BTC + K16 Miner Assembly from 60EUR
just check bizwoos adress in Blockchain, and there is your sending adress

Tnx mate, so I investigated the transactions and this one seems to be my best bet: https://blockchain.info/sl/tx/b55755b37849c0b483fd11c14923329b25383429208e5a450b1abace67e6ab0chttps://blockchain.info/address/1FxazaxsCs4jTYpE3qJm2SSe1YYo3DcG9h
But since I did not send anything apart my chips payment, I guess this address is owned by BitStamp...
https://blockchain.info/sl/address/1Bi11FKZkm6spAPJY43H7HdT7VrBQ6aTW6
So what should I do now? :/ Should I ask BitStamp for more details on the transaction?
