I don't know why people may want to trade the OTC market over the long term - I guess the potential for multiple baggers - but when I understood it's full of pump & dump schemes and fake companies, I got out and invested my time into understanding true fundamentals, technical analysis and macro economics which are more reliable & useful in many more markets and circumstances. If I really want, I could also learn to trade stock options and futures for some leverage.
I also used my knowledge about scammers gained in the OTC market not to get scammed into the crypto markets where I'm more successful because I have a good understanding of the tech.
All in all, I try to avoid fake companies, and I still hope IHAI isn't one.
But we'll see... :-)
