hi all.,
i am not a day trader , so i dont know much about these terms.,
there was trollbox on polo where people used to say pump and dump specific coins. but trollbox is gone now.,
from basic understanding dump means DROP,
does the PUMP means buy ?
First of all never believe in these trollbox and other channels because it's name itself suggests that they are "trolling" you.
PUMP means increase in the value,and DUMP means decrease in the value.
In crypto world we buy during DUMP and sell it during PUMP.
