Bitcoin is safe now for 10+ years and many hacker tried to hack Bitcoin. No hacker succeeded because Bitcoin is proven to be safe.
I agree that Bitcoin network is highly secured now but it is wrong to assume that Bitcoin had never been hacked. There is an incident where an attacker had successfully hacked and exploited network that produced 184 Billion BTC being minted. There is this article that states the event when Bitcoin network had been successfully hacked and exploited.
There is supposed to be two incident but the second incident was detected earlier by the BCH developer (supposed to be previous BTC developer) and took selfless action before it was exploited by the bad actor.
The event when the hacked took place is as follows:

1.The CVE-2010–5139 bug on August 15th, 2010 resulted in 184 billion BTC being minted. On the heels of this event, core developers Gavin Andresen and Satoshi Nakamoto had to roll back the blockchain in order to purge this transaction from block 74638.
2. More recently, on September 17th, 2018, the CVE-2018–17144 bug was discovered by a Bitcoin Cash (BCH) developer who selflessly took action before it could be exploited by a bad actor.
