If Bitcoin will be the only source for you to acquired wealth thru generations, I don't think that 1 Bitcoin is going to be enough. When you talk about generational wealth, something that will give you money for the rest of your natural life and then on the next generation and so forth.

What Bitcoin can give is financial freedom, and then you can slowly build your portfolio from their, so not just on Bitcoin or any other crypto assets that you are going to invest from the money that you build from your initial Bitcoin investment, but you have to ventured on other assets and then established your own business and be a entrepreneur, against have multiple source of income to build a money across your family's generation.
