It wouldn't be a crime or taboo if bitcoin is part of the asset that you can will to your child.
How you pass Bitcoin to your next generation is entirely up to you. You should make arrangements so that someone in your family can take your bitcoins in your absence if you die. Now you just need to focus more on buying and holding your bitcoins for a long time. If you only think about how you will get your Bitcoins to your family after you die or what will happen to your investments when you die, you will never be able to invest and keep those investments for long. If you already have an investment then congratulations you have done the right thing and if you are planning to invest in Bitcoin then you are welcome you must invest in Bitcoin now and hold that investment for as long as possible. None of us know when people die, our life is like a bet. Since there is no guarantee in life, there is no point in worrying so much. Keep going and keep investing in Bitcoin. Maybe you will see that God has kept you alive for a long time and you will get the benefits of your investment for a long time.
