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 ?
No.You are wrong.Pump means a coin deliberately made to increase in price by continuously placing buy orders higher than previous order's value.Its mostly done in altcoins especially in newly released coins by the dev team itself to create a good image for that coin.
Every coin pumped would get dumped.After pumping a coin to some high price,sell orders are placed continuously lower than the previous order.Big whales also use this pump and dump technique to make huge profits.
