I am not frequent player of secondstrade but today i played it very much and i enjoyed the transparent concept behind it, i appreciate it.
The thing which hurts me is its unconfirmed transaction which secondstrade sent to me , because of it all my transactions are becoming unconfirmed.
Please look into issue and drop your unconfirmed transactions and reissue pay with good fee.
