Trading on the OTC market

Hi all, so I’m fairly new to this otc stuff. I believe I understand it pretty well but wanted something cleared up. So if I’m a buyer in a pre market otc sale on Kucoin or similar, I buy presumably at below market price ? Also, according to their rules, the seller has 4 hours to deliver tokens on launch day. Let’s say he complies. I get my tokens. So I’m maybe ready to see what I can sell at. What if in that 4 hour window, price dumps to the pits of hell? Seems like what is even the advantage of this unless it’s simply to get a relatively good long term position after the token settles out. Appreciate any clarification.
