What do you think about Augur? This altcoin jumped by half in about 24 hours.
that is the clear definition of a "pump and dump" coin. and now they are pumping it which is why the price has jumped up that much in a very short time.
Is it worth to buy it?
although it is already too late obviously, but you should generally know that whenever you see a significant rise in the price of an altcoin there is a good chance that it is already too late since pumps don't last long specially in smaller coins.
