Like every other investment such as real estate, stocks and other forms of investment we know that you can invest in that kind of things and then you get something like say a Certificate or a Binding Document as a proof that you are part of that investment, now that of bitcoin all you have is just your address, your password, key and seeds as proof of the ownership of the wallet.

BTC

So now if one is considering buying bitcoins and saving for his/her children in the future is there any way to do that with bitcoins apart from having to write down your details somewhere. I'm asking because with that kind of stuff if no one knows your seeds or password no one can get the coins.

It's fun doing it to save bitcoin for a child and I've done it earlier because I see that the cost of living is getting costly and education the same so I have to do it for my kids so in the future they will be useful and what they want to achieve is achieved so also in investing, they already have enough savings for living expenses and venture capital.
