Hello Steemit...
Pump is a situation in the market when there is a rapid and unreasonable increase in a particular cryptocurrency's price. It often occurs as a result of actions carried out by experienced traders. Usually, after a successful pump, the price goes down, and that scenario is called dump.
Dump is a completely opposite situation in the market. Dump is an intended sell-off of the asset in large volumes, aimed at lowering the cryptocurrency's price in the short term. Dump, which follows pump, allows manipulators to make money on gullible traders who bought into the coin at the price that had been artificially increased in advance.
