Have any of you made such kind of trade which is a coincidence or through some insider information.
Like never happened in entire timeline until today! In fact it is the very reason I stopped playing around most of the altcoins because they are dumped as soon as they get listed and they never come back really. Due to free giveaways which is most common practice in the ICO, Airdrops, Promotions, Bounties and what not, millions of tokens are dumped if the project is successful in listing their coins over an exchanger.
I have observed closely, the project will always claim they will have listing price of lets say $10 but as soon as they list there are legend players who will have those free collected coins and start dumping right at that price and by the time investor like me reach there to take profit or even wait in some instances in a hope that I will get more in the future, I will loose everything in the process.
The insider job can only be done by two people, one the owner himself and secondly the people who work around the owner.
Seriously, this is why most of the altcoin project fails in the first place. Those which survive are always running on external oxygen per se.
