send BTC from Jaxx multi-key wallet and sign with ETH address - tenx ICO

[wirrwar]

Hi All,

I send some funds to the tenx ICO today and the transaction also went through. Now I wonder which address I need to use to sign the transaction.
If I look at the transaction ID I see that 2 public keys (I hold the private key) where used.

Do I need to sign each one separate with my ETH address so tenx can send me the token? Tenx said they dont support Jaxx since its a multi address wallet but I just stupidly risk it and now wonder how I can get it sorted..

This is it: https://blockchain.info/tx/6d682742bf47a87f16dfbf9dc8bcf62bcf49bd68d169350e95679088a3442768

Thanks for your help,
