I assume you are talking about ENTI, not PTEL since I didn't ask for the PTEL shares.
If I came across ENTI right now for the first time and did my DD I think the large OS would stop me. I would simply look for better prospects. There would be no point in going to an "expert". I had my share of "experts" (full service brokers) 20-30 years ago. None of them made any money for me. If I am going to loose money I at least want to be responsible for loosing it. Imagine if I had given Bernie all my money.
When I first invested in ENTI the OS was much smaller and the pps was running between .002 and .007. I probably invested more than I should but one is always taking a risk with OTC stocks. Do you know of a fool-proof strategy that lets you bat 100 with the pinkies?
