Such a severe bug could easily destroy the coin, if it not already did so.
if the dev know a little about logic, they will realize that the hacker has stolen from them not from the community so in my opinion the should destroy 370 000 XZC send them to a vanity wallet a wallet without private key. that will bring a little confiance in the dev.
Please enlighten the devs how to destroy it when the coins are already sold on the market? No one has absolute control of that hacked coins now, how to gather them in one place and burn ??
