Some investors will feel like they will do the security thing later. They are more concerned about buying and trying to accumulate wealth, while some don't trust themselves that they can protect their wallet well, which is why they leave the security task with a third party by trusting ETF or centralized exchange but the price they pay for such decision is that they don't hold total control of their investment.
Security is the most important thing to do, together with privacy. Security and privacy mutually interact and support or damage each other, so if we want to have good security, we also must take proper care of our privacy practice.
Security if is compromised will result in wallet hack, fund loss and with Bitcoin blockchain, when a transaction was made, and confirmed, we lost our bitcoins forever. It's realistic to assume we lost our bitcoins forever because chance of getting support from police, arrest the hackers, get our coins back is very small, almost impossible.
Security is important for all of us, no matter we are investors or traders.
