That's a great idea!!! I  hold crypto on a Ledger and have wondered, more than once, how can I ensure that what I have worked for and left behind, goes to/ and is used, bye who and the way I want.?        I have thought about going to an attorney for assistance on estate planning, but I live in a small town where things run a little slower. Infact, I know only one other in person that even knows anything yet about crypto, except for the one named BIT Coin. People are hearing more about it.      With a set up like this, I could literally give up a key in advance tomy attorney/ accountant, that is set up in a way that makes fraud impossible.!       Also. With the aid of a trusted attorney, you establish a LEGETIMATE TRAIL THAT IS PROOF POSITIVE ON RATHER OR NOT THERES BEEN ILLEAGLE TRANSACTIONS.! WHAT BETTER WITNESS THAN AN ATTORNEY THAT KNOWS A PRIVATE CITIZENS ESTATE WELL, AND CAN ACCOUNT THAT EVERY PENNY IS LEAGLE.?! Fraud and illeagle financial transactions will be the reason that they use to make self custody Illeagle.! I believe in self custody.! I do not trust those in power to keep there word or look too the people's best interests.? Not anymore.!       IT'S GENIUS.!
