It wasn't a "pump." I was there when it happened and also bought in some. Look at when prices rose. It was because Bigvern (@Cryptsy) had started tweeting again after long hiatus.

Once people realized that the EAC delay *was* due to backend upgrades, then people bought. No one was buying for awhile because the price to keep dropping so they could buy in cheap. However, once @Cryptsy started tweeting, people wanted to buy before the price went up too much. Then, the miners holding on to their EAC took some quick profits driving the price back down and people stopped buying so they could again buy back again slowly at lower prices.
Either way, The coin processor CoinPayments just announced they were going to be accepting EAC, so that should open up the door to widespread merchant adoption and growth. Out of all the coins in this poll, it clearly has the most *legit* support.
