fast pump ?

[OmegaStarScream]

Couple of hours ago I checked the price on preev.com rates and the price was about 274$~ or something like that , now it's back 250$ suddenly what exactly the cause of those pumps , just some regular exchange websites manipulations ? also what's your expectation till the end of this month ?

I'am not sure what a spike means but Preev.com rates are absolutly and 100% legit as far as I know , using it for over a year now and he take from different sources : LocalBitcoins , Bitfinex , Bitstamp and also BTC-E
I was the only one who saw that price changing ?

As stated, the price data is continually gathered from multiple markets. A weighted average price of these markets is shown by default so essentially what it means is that there is a probability that on one exchanger, large orders could have been executed causing the remaining supply to be sold at higher price and thus drive the numbers up.

cant it be just some kind of a bug on the preev, maybe something happened and it showed incorrect prices for a while and then it was fixed

Most likely yeah since no one really took attention to the price then probably just a little fast bug and I was on the wrong place on the wrong time , haha
