They should be aware of the internet world that everything is unsafe and very vulnerable to hacking. Make things as complex as possible so that hackers do not easily break anything valuable in the internet world. Hackers are on the wrong path, if hackers can be properly employed, maybe they will make a strong security system to apply to important and big websites in the internet world such as exchanges etc.
It should be the opposite, complex systems are easier to manipulate and are more likely to be induced to error, exchanges need to strengthen their security but at the same time they need to simplify it so it is more difficult for hackers to get access to the exchange, but since exchanges grow depending on the demand there are exchanges that do not have the adequate security because they became very popular in a short time frame.
