Better way is just leave or give to you family since in the next world cryptocurrency will be useful for you for shopping, but we don't know what is beyond the limit, maybe it's only cryptocurrencies that go and trade with might and main on exchanges) But I think everyone agrees on what to leave the family, but there are many people including in many families who do not know at all how to use a wallet and how it works in general (how to check the balance, how to sell, how to withdraw), and it turns out that all the savings in the crypt can simply disappear due to the ignorance of your relatives that you have some savings (anything can happen to anyone at any time, unfortunately). And how to find a way out of this situation? Tell, show, teach in advance? Well, how else?
