We should all be reminded that there is no 100 percent secure system or in this case your Bitcoin holdings and any assumption of its solid

security  would be dangerous and we should always be security conscious and practice those actions mentioned in previous posts. I think

using a hardware wallet would be excellent but I suggest to try to harden your pc security (e.g. use firewalls, antivirus, use VPN, password manager

etc) to make it more harder for intruders to attack your system.
