You're giving dickran far too much credit. He/she is just a greed and hubris driven individual, incapable of admitting mistakes, who thinks he/she is smarter than everyone else. The reality is dickran bought and held erhe all the way down from close to $1, doubled down after the reverse split, and is stuck with close to 400 million erhe shares.
Right now however, I am more concerned with why you are posting wild assumptions that contradict the facts even though the factual info is readily available. You even provided links to some of it. You expressed concern about small amount of volume over the last days which was less than 2% of total shares outstanding. You posted nonsense about convertible shares. Then you even implied that dickran had sold close to 100 million shares when the filings you linked to show that is not the case. Just look at the dates and you will see the 3/11/2019 filing disclosed ownership of 306 million shares and the one that followed on 3/20/2020 detailed the purchases of another 99 million shares bringing dickran's total to 399,303,010. No where is there anything showing he has been able to unload.
I thought with dickran cowering in silence the need for debunking false claims would diminish. If you want to post, it would be appreciated if you take the time to fact check yourself so someone else won't have to. There is obviously something underway with the recent price and volume. I hope it is based on factual positive erhc developments and not just manipulations by stuck longs desperate to get out. erhc management could clear the air, but they haven't done so in more than 8 years, so good luck with that.
