Do you mean that the exchanges are showing to us volumes, which are not "quite correct"?
In low-volume-markets it is easy to manipulate the course values, if someone has money enough. Eg. buy the whole selling wall and then it looks like the price went up to the moon +60%
That kind of changes have happened also in stock markets with some company's stock, whose day-volume is very low.
Maybe, but to be precise i mean that market maker (there is always such person or group of persons) can do with his robots false volume (per multiaccounts) at low cost, that is possible also in case of exchange (no costs as no fees).
This things are maked to create false pumps, and these false pumps are maked to create opportunity to sell collected coins from lower lewels to the FOMO players with good profit, sometimes this pumps are propelled by good news or statements to create really good profit ratio (espiecially for insiders).
This is wild market, with one rule for small player: newer tend to FOMO, try to buy when You see possibility of dip, try sell when You see FOMO and never get in for all You have!
I dont say that insiders or exchanges do it in case of XEM for sure. But that is my impression. I observe this market day by day, hour after hour.
Some thougths about current price action:
https://forum.nem.io/t/nem-xem-price-charts/1204/4?u=ormrlangiToday is the last day of poll and option "Move snapshot with the launch date" probably will win. What this can cause to price? For sure there will be more time for accumulation before snapshot i bet big fishes will try to make mechanism of reversed FOMO in exchanges, to get cheap XEMs from impatient people.
Now i try to rebuy @0.22$ some chunk of XEMs that i gave up some time ago, my main pending buy in Bitcoins @ 400-460satoshi area stays untouched, just in case... Howgh:D
edit// and the holders voted to not risk and move snapshot along with the launch date, price is stable @22cents we will see if it will hold, if not 400-460 satoshi as i wrote before.
