This was also on my mind, some degen pulling in their PEPE bags.
Spear fishing is about accumulation, normally does not press this hard. You "spear" up into the liquidity, but then "give up" and put in a big buy order back where you started or a bit higher.
A few days (hours) later, you spear again - giving plenty of time for arbs and noobs to quick dump their hive (thus providing more liquidity for your next spear).
