I guess I could buy a safe and do it the way you suggested, but it still does not solve the problem with forwarding the safe password / code to the beneficiary in the first place. Neither does it make the regular updating of all the accounts and passwords more convenient.
And there is even the problem, that at the current state of "wild-west-crypto" I can't let my wife know, that I am 'playing around' with our money in this 'big experiment'. If I get a safe, she would want to have access to it from the start and she would find out and worry unnecessarily all the time.
So the only way to really make this work effectively would be depositing this letter at an attorney, notary or a bank box. And that is neither free nor convenient. So I'd still prefer to have a smart contract with an effectively timed trigger to pass on this secret to my inheritors.
Or to put it other way - just because we can ride horses already it does not make the development of cars unnecessary ;)
Before telling my wife that I was already in crypto, I watched a few videos about it with her, and then one day when the price fell heavily, she said “Let’s do it”. Women are much better at timing things than men.
On the deferred Will or deferred letter idea, I am sure the solution will exist very soon. Can you try and live a couple of years?
Thanks for the hint, I might try that out. My biggest fear is that because my wife is a lawyer she can very well figure out the risk hidden in the actual legal consequences of the current state of the regulation-free crypto space, ICOs especially. It might get really hard to get her on board ;))
And yes, I actually do my best to not to be in a need of a DigiPulse service any time soon :D
