I think the speed people take to claim a coin like dead is even faster than that they usually take to cry at "moon", "breakthrough", "revolutionary" at every launch. More sense of proportion would be needed. After BLK great pump&dump (april 2014), recurring comments were "this shit is over, get out asap": now, more than one year later, I get a remarkable  profit staking the blackcoins (a lot) I bought on that dump. I could say the same for many other coins (vertcoin, faircoin, dash...) I bought on dumps and hodl still now. This doesn't necessary mean archcoin will have a future for sure but, for now, i grabbed some at 7k and stake. Time will tell.
