Answer: While it is true that increasing the lock time period up to 4 years often does provide more security for token holders, it is not a permanent solution. Eventually, if less people stake in the platform, the locked tokens will not be relocked, meaning that the security provided by the extended lock time period will no longer apply. Therefore, it is important to consider other methods of ensuring security of tokens, such as ensuring that the platform has robust security measures in place, or implementing a system of regular audits to ensure that all tokens are secure.
