With many bankrupt Exchange listed stocks that get delisted to the OTC often there are large holders. eg., Institutional Holders, Insiders, loan holders with equity, that can run a stock so that they can get as much money as they can for their shares. That practice is illegal and amoral but they can do it anyway.
Throw in penny stock OTC players that can also run a BK stock on horribly false information (they don't care!!!) and the stock could go on a contrived run.
I don't advise on OTC stocks but you could consider watching for either, or both of the two scenarios above.
To bite the worm of incite is to bite the HOOK of the antagonist . They win .
