In my view, it depends on your Crypto wallet, and also to do with the hardware wallet IF you are using, as that gives the security. I use Coinbase, which I feel is HIGHLY safe and secure.
I think every exchange could be hacked sooner or later. Coinbase has access to your private keys. So I can't call it secure I guess.
To me crypto in general is not safe. I must argue more better security as exchange hack wind up normal. I prefer the most legitimate, demonstrated, secure spot to store my coins. There's always a way an exchange could get compromised. The computer could breaks, USBs gets lost such issue needs to get attention.
And those hacking news are going out considerably frequently. In these two months of 2019, some reputed exchanges got hacked. I am really concerned now about exchange hacking and crypto security.
