Easiest way to see bitcoin’s value proposition is to consider the following scenarios:

If you have 750K in the bank, it’s relatively easy to get to 1MM. An 4% return gets you there in about 7.5 years with virtually no risk.

On the other hand I would argue if you have 7.5 bitcoin and wanted to get to 10 bitcoin, that is a ridiculously difficult road with even an above average income and under control expenses.

And like most things in life, those that are harder to attain are worth more.
