As a fan of Black Mirror series, I made bunch of cold wallet and printed notes for my wife that if there suddenly something bad happen to me one day (kidnap, nature disaster, or accident, that's life who knows?), you have to know what I have been doing and you have to manage those things to sell them all or to continue my work so we might guarantee for the future of our kids. The problem is that, my portfolio changes constantly, and it's hard to manage all of those coins if you're not familiar to crypto currency, not to say if I forget to update it on time.

The born of Dero embraces my hope that one day I can create a smart contract that could automatically swap all my coins to Bitcoin/ETH/Dero and send to my wife coinbase wallet if mine is not accessed for 1 year, just in case I'm gone.

And if no one can see the contract, just me and my wife know what we've got in there and what we gonna do, that would be perfect!
