So, it is best to set a nominee system and also a recovery of post password system in the platform will much better, if some user lost their interest on steemit for any reason, then their kids can access to it's coins and claim that.

I agree with this point, but the downside is that if a password recovery system is set up, then the potential for hackers to break into your account is much less vulnerable.

Thank you for your participation in the contest that we held at the Steem For Betterlife Community, I wish you the best for all of us.
