The same risks still apply as they did when it went to Expert in 2021 - if no shares are traded for 12 months, FINRA deletes the symbol for inactivity. It can be reinstated, but the company would have to show they are still an active company first.
As far as the “30 days no trades” thing, that was an etrade policy that would liquidate holders of securities in Expert if there wasn’t any trading activity for 30 days. But most of the OTC has basically been dead with no volume for so long now that anyone who had this stock in an etrade account probably already got liquidated.
The other potential risk, although very minimal, is if the SEC changes course and decides they can revoke voluntary filers for delinquency. So far in 3 years, they’ve only gone after the true delinquent reporting companies and not “333” voluntary reporters.
