I do not think I get it - there is no way to sensibly pool 50k HBD with 50k of real altcoin, so I have to assume you just want load up an near-empty HBD/ShitcoinABC so that you hold 99%+ of it.
Now if you spike HBD to $3, people start buying ABC and pumping it into your pool until you end up with little HBD and big bag of ABC that has no value.
More generally, if you are going to pump HBD, you exit all LPs first. To exploit the pump, you just buy HBD from any pool you can find, shortchanging those who left their liquidity in (and rapidly resell HBD elsewhere for the inflated price).
