I.e. you can create the Hypothetical Token (HYPO). Mine 50k HYPO and create an LP with 10 BNB. You promote the project, people start buying, exchange their BNB for HYPO. Now your LP has more BNB and you can disarm the LP, receiving what it has now. Which are the BNBs of all the people who bought and the HYPOs that did not sell. And those who bought have HYPOs that are worth nothing and that they cannot sell because there is no longer an LP.
