Well every project which succeed attract some people trying to spread some fud.
Well, i don't want to bash other projects, but if you have been watching Monetha announcement, you'll understand why they are angry at the new competition.
I took a look quickly, what's the problem ? That the current price is under the ICO price ?
Usually this is because of bounty hunters, they got monetha for free, then they just dump the price, sometimes I wish there are not bounties at all, but they are important for the marketing XD, or perhaps they should distribute the tokens 1 month after they distributed to investors, that will prevent dumping at the beginning, but that is just me, the other option I saw some other projects, is to pay with eth or BTC to the bounty program, so the token itself is not affected

, Dimcoin did this with their facebook and twitter campaign.
