"Pump and dump" - Great for Tinder, bad for investing.

Recently I have seen more and more advertising for "pump groups". Pump groups promise members "easy money". In reality these groups are a scam and the only ones that benefits are the group leaders.

How a Pump Group works

• The group spams public message boards/steemit etc. to get members to join their telegram app.
• Leaders of the group decide on a coin that will be "pumped". They buy into this coin day/weeks/months in advance to buy it as cheap as possible.
• Group leader announces that a pump will happen on exchange XYZ at time/date. Members still have no idea what coin will be pumped.
• Leaders of the group place a bunch of sell orders well above the current buy price of the coin in preparation of the pump.
• Group leader announces the coin and members go in a buy frenzy. In reality all that is happening is the members are buying the leaders overpriced coin. It's a game of musical chairs and the last one to place a sell order is stuck with bunch of coins they overpaid for. The entire "pump" lasts less then a minute and the only people that make significant monetary gains are the group leaders.

Summary

Members of the group pump the coin while the leaders dump it. Stay away.
