I don't know about the safety of the encryption's quantum resistance. But I do know that those in control of the blockchain will stop the chain, and even revert to an older state, provided that an illegal change is implemented. They will even update the code to lock out addresses that have altered their rewards. These things have happen before in the past, and hot fixes were rushed out to isolate these wrongfully allocated funds.
Now as for your personal system getting hacked, and your keys getting stolen.... You're on your own on that.

You shouldn't be on your own like that. Satoshi wouldn't have let that be.
