I checked my counterparty account. There is only NVST but no NVSX. 
The whitepaper mentions that it an automatic process where once it receives the NVST.

"Upon the detection of NVST inside a user’s wallet, the validator will issue a 2OF2 Bitcoin address containing the amount of NVSX based on the
user’s amount of NVST. It will then create a redeem script and send it to the holder wallet."

How long does that process take? I have received only the NVST
