"What happens to my crypto if I was to die unexpectedly soon?"
I am sure many of us have a plan if they die soon. Perhaps, they will give their crypto to a beloved person before they died.
1) Include all your wallets and passwords/seeds in your will. Make sure you include instructions on how to access your funds as well as giving these to someone not familiar with crypto will be just as useless as not even including them in your will.
2) Along with the will, teach the closest person in your life how to access your funds. Whether this is your significant other, family member, or really close friend, make sure someone understands how to access a wallet and transfer/sell the funds. Just like how you should be researching projects before you invest in it, make sure you choose who you share your secrets with carefully.
Related to numbers 1 and 2, I think most of us already prepare for that, and they will give all their wallets and passwords/seeds at the right time. They already teach their beloved person how to use the crypto and tells about everything they know for that person.
3) Take a look at Safe Haven. Safe Haven is building an Inheritance Platform that will allow you to do everything above, but with a legal entity that understands crypto and will make sure your funds get in the right hands.
I don't know anything about that project. I instead choose the profitable crypto like bitcoin and the other altcoin list from the top 10 or 20 at the coinmarketcap as the investment. But I want bitcoin as the main investment, so if I died, the person who I choose could use all of my cryptos without a problem.
