This is actually a good idea when somebody asks about how if they die today, what will happen to their BTC. Actually, if we have someone we trust most and he is trusted, we can share about our asset with him/her. But of course, it must be the one that we trust, really trust.
And about inheriting our BTC to our son after several years by setting the speed of the transaction, it can really be implemented. But, i wonder, is it really safe and will arrive at that time? How is there is something error? of course, it may be one of the risks.
What happens if someone who sets, for example, 20 years from today's date but they don't die? Is it possible to cancel this transaction?
Isn't it true that if the transaction has been confirmed, we can't cancel it? I also wonder about it, if we really intend to give it to someone else, it may not be a matter for us because we just let it arrived at the address.
