Now that most of the people are well aware of scam ICOs, scammer has found another way to scam people. I have observed 3 projects till now which I will list here and give you a highlights how they scam people, specially the newbie.

1. Privcy
Privacy was a free airdropped coin which was distributed freely over the community for helping promoting the project. Later, they decide to reward more to the holder of the coin in airdrops. The more coin you hold, the more airdrop coin you get. Newbies started to buy coins for getting more airdrop coin and DEV were selling their coin. I am sure they had a lot of fake accounts participating in the Airdrop. Can you believe they scammed people in such a way? Now, the project is died, 24 hour volume is- $620 which was less than $100 couple of weeks ago.

2. Profish
Profish was an ICO which came into the exchange before the bounty end. They were listed in mercatox and used to have some fake volumes. I don't know what happened to their ICO but they sold a lot of coins through mercatox and later, the price is now 1 or 2 satoshi from 650 satoshi. This is also a dead project. They scammed people.

3. Helios Protocol- Be aware
Helios Protocol is now airdropping coin to their community. This attract my eyes when I see user vectisitch was vouching the project. He was a moderator in privcy, so, there's no doubt that both of the project are from same person and this helios shit is also going to scam money. I want to alert you guys not to invest in this scam project.
