Another thing is even though we know that nowhere is safe even though centralized exchange is reputable, we really still need to protect our funds by avoiding storing your cryptocurrencies on the exchange, you can create your personal wallet.
Another thing is having knowledge abut scams/hacks just like identifying phishing sites or some scams, it is really helpful.
When I have another crypto on an exchange and it's at a large value, what I do is first transfer it to a wallet where I save an address with a private key. Because I don't have the money to buy hardware yet, I only use the meta wallet first. As long as I'll make sure I have the private key and I also write it down on paper and save it on the USB flash drive, no matter what.
And so far, so good right now. For at least my crypto assets that are outside the exchange, it's difficult because when there is a hacking issue, I can't release my crypto from the platform because they will suddenly freeze the accounts of their clients for sure.
You are absolutely correct, when I’m feeling lazy I just leave some for easy accessibility on cex to buy any altcoins. One thing that stands out about cex for me is the accessibility & prolly some airdrops events lol . Gotten few from bitget over the months
