If you can own 1 bitcoin and hold it indefinitely, surely it will be a huge amount after a decade or two.
I don't think that in 10-20 years, bitcoin will have a huge value to create generational wealth. The higher the price of bitcoin, the harder it is to increase the multiple of the profit you get. The wealth in bitcoin was made by early investors because they could make x100-1000 profit by buying for a few cents.
When you use that massive returns in buying another assets like real estate, stocks or bonds,
The
BTC-community will not approve of such actions with bitcoin.

Just hodl.!
Why buy this junk (except for real estate, if you live in it), when bitcoin shows higher profitability.
and pass it into your children, that means a single bitcoin has already led into a generational wealth, that is if you manage your investment wisely and smartly.
Will it be considered a wise investment if it converts bitcoin to
another assets like real estate, stocks or bonds,
You can also pass on bitcoin to your children.
But if you are a greedy one and is up for get-rich-quick profits, owning 1 bitcoin would never be enough to become a generational wealth.
Having 1 btc will be enough for the poor people, but for the rich 1 btc (~$60k now) is a trifle.
