it's very difficult to recognize will it be or not,
but from my experience the way i feel it by reading the buy/sell orders and the news.
usually there are no 'big sell order nor buy order' in the buy/sell oders,but suddenly in the next hour you can see a 'big sell orders',
mose people using that sell order to trigger the weak hands,because of that the price will goes down and the strong hand accumulate more coin.
after a few hours usually they will take it off and start the pump.
(actually it can not be say as a way to recognize it,but it's some clue how it works)
and if you heard there will be something in the next month,
usually the price will be pumped a few days before the news come up.
and when the news come up that is the time to dump it
This is difficult, if not carefully observed. Didn`t we know that Bitcoin is similar to gold (a tool of sale or a trade tool). According to market analysis I noticed, traders usually will offer their merchandise at a low first price. If there is a long queue of buyers, then the sipedagang will raise the price bit by bit (there is a pumping system), a trick like this has long been done by traders all over the country.
Therefore, I personally pay attention to it from "buyer traffic"
