In the future if you have one btc and it cost 40k.

Those who got crypto will own everything.
It means with 40k btc you have purache power 40k x 40k=? A lot lambos a lot lands a lot mansions.
Depending on how Bitcoin's journey is going forward, whether there can guarantee that Bitcoin's length will be worth it, indeed, if it is noticed in the next 10 Bitcoin is still the king in Crypto, but the competition between other coins cannot be ignored, the mathematical count is true as you describe, But it's still very speculative, why not looking for a potential short-expected coin to get big profits, isn't it more promising.
1 bitcoin will still be 1 bitcoin but the value of money will change every time and maybe if 1 bitcoin becomes $100k, that means your money value will be like that.
The bitcoin journey will be exciting because we have seen what is happening with bitcoin so far and we recognize that fluctuations in the value of bitcoin will continue to change.
As long as the value of bitcoin continues to rise, it will make people keep trying to get more bitcoins so that when the price goes up very high, they can get double profits.
That is why, until now, people are still using bitcoin for profit because they believe that the value of bitcoin will be very high in the future.
