Thanks for the reply. Then i assume i need to send the bitcoins from directly myetherwallet and not poloniex?

I sent them from my Polo account and it worked just fine. It seems just the receiving address for the Beth tokens needs to be MyEtherWallet.

Aha, i now got it how it works. I see the wallet address generated is a temporary one, every time you make a transaction there is a new one. Otherwise i was thinking how it would relate every deposit i make to my personal wallet? Thanks, will try it now.

No worries! Thanks for the feedback and questions!
