Last but not lease, security is not a one time task, so think long term because it is an ongoing process. the security habit you develop today can protect you from losing years into the future. most people, especially newbies lose their bitcoin investments because they focus more buying and ignoring how to secure them.
The problem is they tend to focus on the positive side (profit) more than the negative side that is mostly associated with the security part. But I don't blame them, I blame some people that claim to promote bitcoin on one side narrative. Most newbies never try to verify what they have heard about anything, they rely on what they hear to take action. When you tell them about the potential profit in bitcoin without telling them about the security security architecture, you're indirectly misleading them to sow what they will probably not reap. Security should always come first before any other thing. What's the point of rushing to buy something that you have not plan how to make sure it is secured?
