With such grups you are chaising tail. and only leader of pump is getting hard cash rest most likely will sponsor his earnngs. You will most likely loose money there.
That's correct. Rarely a public pump group works in the long-term. Mainly because the manager of the group which usually is the guy who starts the pumps, probably has already bought amounts of the selected currency and will always try to profit from the new users and beginners mistakes.
I can speak of this from my own experience because I was already part of a group like this, and it never worked well.
The best way to organize an artificial pump is with a private group of whales that own a large amount of BTC, and are willing to allow the whole group to profit, controlling their greed to avoid disasters.
Yep, with public groups there are always some guys which step out early, causing everything to crash down, since FUD will trigger them. I've never made any profit of these P&Ds. It is a complete waste of money.
Just to add to the last post which is spot on: you do know this is completely illegal right? So why not just go steal some money from a convenience store? It'll probably be easier than this and pay off more. (I'm not saying you should. I'm just saying they're both crimes so why bother going though this trouble to commit a crime that you probably won't even be either from?)
Is it illegal to pump a coin, or is the recruiting illegal? Free market right?
