Until the uplist is here, all spikes are because of OTC momentum. I think it is due to all new people brought to the stock market by the recent Wall Street Bets fiasco, the natural thing for new investors to do is look for cheaper stocks to get a bigger bang so they go for the pennies/OTC. Now that the hype is over everything is going back to normal. Luckily for RXMD they have more going for them than the majority of runners so they may not fall back to pre February levels.
