Many OTCs are updated daily but $GSTC has a history of slow updates (every 2-3 weeks it seems).
When its been 3-4 weeks, during which we've seen heavy volume (which I've posted about previously) THAT IS WHEN we expect to see (and do see) O/S bumps.
As you've pointed out, there is no other source of finance.
As I've pointed out, because of that we can reasonably expect O/S to continue growing throughout 2024.
