Attackers recently spent a lot of resources (over 500 MH/s !!) to bring FeatherCoin down. And failed. Because FeatherCoin has a determined team that actively develops and maintains the coin. And FeatherCoin has a very strong community support:
http://forum.feathercoin.com/Every other Alt-Coin would be long dead by now if it had to take the beating that FeatherCoin had to take.
The attack that has been unleashed on FeatherCoin would have most probably killed coins like DigiCoin (current network speed only at 650 MH/s) , WorldCoin (current network speed only at 400 MH/s), etc.
For sure it would have killed coins like CHNCoin, where the developer has jumped ship the day he released the coin.
The question remains: Why this enormous efforts to kill FeatherCoin? Who's so afraid of FeatherCoin? You only fight what you fear. You only fight what might threaten you (in the future).
I am 100% sure that FeatherCoin will be a success story. Others obviously think that too. And spend lots of resources trying to kill it.
Price on btc-e is stable, even rising.
The market has spoken - the attackers have failed.
