Dreams and oracles nothwithstanding....right now its still speculation.  But you are right Koo...if an application is made and then accepted for a Nasdaq listing, then RVXCF would be replaced with whatever the new symbol would be....our listing (according to the July 31/18 news) on the TSX would remain, however its possible there would be a new TSX symbol as well.  

As for WRTC (the symbol for Wrap Tech) it was an OTC stock before, here's their initial prospectus from Aug 2017:

In there it says:  A market maker has filed a Rule 211 application with FINRA so that our Common Stock may be quoted on an interdealer quotation system such as the OTC Markets.
