The attackers have taken a short position during the decline (causing the decline), and when they run out of coins, the price also stopped declining. When it started going up, it was the time to attack.
Now if the holders sell their coins so that the price drops to below 400, without corresponding buyers except the attackers, then the attackers have won financially, fleecing the community. (The community has also won, because the bug was fixed and attack repelled.)
I pledge 1000 XMR to the devs for their ongoing good work, and BTC100 will be used to buy moneros in the exchange without further warning if I deem that the scamattackers are about to get too fat a profit from their attack.
I will use another ~BTC10 to buy XMR once the time has come (/ trading continues).
I'll put at least 5 BTC on the table for buying and I'll donate at least 25 XMR when problem is solved to the devs.
By putting your order at 0.004 you are supporting the floor.
I will chip in some myself.
I pledge BTC5 in buy support, and will also make a contribution to the dev team.
