That contract is different from SNX. At least it looks different to me. Here are some comments by other users:

I would not waste time and gas on it. It's most likely useless and has no value. You will always be able to exchange them in the future, if I am wrong. Don't do it now. Smells like a scam.

Create an account, send them there. After that you can swap to BTC or ETH or whatever you like.
