If bitcoin were to die it would have died after Gox. Those were dark days.
Finex hurts, sorry to those who are involved, but Bitcoin itself is working as designed and remains unaffected.
If you want rollback guarantees from a central authority, try Steem or Ripple or Eth ( Specially Steem :) )

I don't understand why the fuck people keep all their assets on some exchanges instead of either in cold storage or at least on their f*cking computers. I get that it is easier if you are a regular or a instant trader to have some of your assets on the exchange's wallet. But only SOME not all of them.
