PopCash Bitcoin Deposit not possible?

I want to advertise Popunder traffic in Media/Entertainment Are but I want to pay In bitcoin

I saw Popcash showing Bitcoin logo on their site so I thought it might be possible to deposit with btc but i think you only can cashout in btc :/

Any other Popunder networks that you can pay with btc?

You can deposit via btc. As well almost every big popunder network now accepting bitcoin.
