This is bad and will likely turn investors towards other privacy coins like Monero. That is, if a team can't protect their blockchain and give hackers a taste of what it feels like, that is to say the platform will find it hard getting investors or users who will trust them henceforth, and considering it is a privacy coin which is believed to be decentralized, this is a bad one for them. Or maybe it could be that in the process of developing a new feature or protocol like the Chainlock as mentioned, they made a mistake thus giving hackers the loophole they are looking for. Nevertheless, I hope they come back stronger and better, while giving investors good reasons to keep trusting them while also using it for anonymous purposes.
