You need to learn to develop self-confidence in order to really work out well.
Not just self confidence but also self-awareness because hacking is something that you can't be a victim of unless you somehow gave the hacker your information. There can be emails that contain phishing links or there can be brute forcing methods applied by hackers to gain access to your accounts.
What one needs to do is just set a strong and different password for each website/exchange and make sure to avoid clicking any emails they receive from unknown sources and verify the sender's email (sent-from).
I am also being in crypto since a long time but I never got hacked because these are basics and I was always aware of these.
To survive in the long run you need to be aware of what can hurt you, and to avoid that of course. Any rushing in unknown is risky, trying new things is risky, but if you do your research, if you check all the angles, before you try something you can save yourself from many troubles.
I am in crypto for a long time too, and we saw many scams, and many victims. We have to learn from that and calculate our steps, there's no magical protection, education is the key, it's how you protect yourself, with knowing what is around you and how it works.
