well
if that coin is useless coin , just like a easy way to get money.
but if that a good , like a top 100 coinmarket.
i think they need a big money to make a pump dump scheme.
about newbie , i believe more exchanges sites already announced about crypto currency is very fluctuactive
considering exchanges sites its a initial steps to get started
For the first time they might would feel that's a crazy market , unbelievable and sucks experience. But you know it won't happened last forever , you'll get sweet profit and realize that the last time it was a pump and dump did intentionally not an ordinary market.
