Doubt that OTC will halt CRYXF trading over the CCAA.
Companies without a visible means of income support, or a legitimate business plan, or employess, etc., etc. - mostly shells - trade all of the time on OTC/Pinks. OTC/Pinks is quite the flexible/forgiving/wildwest platform. KRY may be a lotto ticket, but it is definitely not a shell.
So, continued trading of CRYXF should be good to go. That is, until sp becomes a problem because there are SEC rules pending concerning minimum sp for OTC/Pinks.
News of the CCAA has not really been distributed in the US. May take a bit for that to sink in with US spec players that CCAA is kinda like Chapter 11 - without rules.
