3) Malware: Bad software on your computer can swipe your Bitcoin details. (50% of your fault)
4) Scams: Watch out for too-good-to-be-true offers; they might just run off with your Bitcoin. (Your fault)
5) Public Wi-Fi Dangers: If you're using public Wi-Fi, hackers could intercept your Bitcoin transactions. (Your fault, dont use PUBLIC FREE WIFI)
6) SIM Swapping: Hackers take over your phone number and get into your crypto accounts. (Not your fault)
