That's the trick man. Get some friends in and give them the bonus price during presale, and these friends will buy in to the max. Then also there's often a surprise competition, where your friends win the jackpot. And then manipulate / mess up the orderbook before leaving with a coin surplus.

That's the current day ico.

Justin Sun and his rtrd friends do this all the time I believe. At OCN they were definitely there.

And count on these people to do that as well. 7 to 8 out of 10 users you see posting here are on the payroll of the ArcBlock scam.
