The normal is crazy you know. The dump after pump is a manipulation of the price. You have profited and dump again to lower the price of a particular coin and again profit for the dumper. Well, cryptocurrency world is a crazy world. We are all crazy about bitcoin.
I think it's just a thought that comes to your mind. sometimes the pump exhaust dump is normal. however, the price may not return to normal, and it is said to be pumped because the price rises after the dump. not all of these are manipulations.
