On face value, I think OP's comparison is flawed. One doesn't need to have a mansion to paint the picture of success. On the other hand I think I can relate very well with the picture the OP tried to convey with such analogy in value of what that fraction is worth. I think that fraction will be worth more than a mansion at some point in future. I can remember vividly when I used to earn 0.015 BTC to 0.018 BTC weekly a few years ago from signature campaigns in 2017. Then that value was around $120 to $150. But in today's value that's around $800 (if I'm not wrong). It's the same way that 0.1btc which is worth slightly less than $5000 today could be worth $50,000 in future too. One can get a mansion at that cost.
