You can't force Bitcoin to solely be whatever you want it to be. Whether you, me, other people, or Satoshi himself like it or not, people will be using Bitcoin for whatever they see fit outside using bitcoin as a currency — and that includes store of value and speculation. Because that's what free markets do, and there's really nothing wrong with it.

I personally think that the result of optimism is that Bitcoin has entered a mature stage, and has no longer soared and plummeted. Like today's gold, it has become a stable investment product. At that time, I think the btc price is about 10 times higher than it is now. With the relaxation of policy supervision, the public has become more and more aware of it, and its market value continues to increase, and its volatility will eventually become smaller and smaller. This state is defined by me as the "eternal bull market", although the eternal bull market will inevitably no longer have the myth of wealth.

Despite my strong belief and optimism in the future of Bitcoin, I believe that it is not currently possible for Bitcoin to turn into a global currency that replaces all paper currencies and is used on a daily basis to purchase daily needs from the supermarket or other, the main reason is the problem of high fees and the problem of delays in the network, unless the Solving these problems is hard to see, although I am optimistic that these problems will be resolved somehow. Only then can it be said that Bitcoin will become the world's single currency.

there're four possibilities:
go zero
continue the previous ups and downs, TO THE MOON
become a collectible
become a stable currency and become a network currency bank
Among the above four endings, most Bitcoin believers and their apprentices must acquiesce in the second kind. They firmly believe that the previous so-called rules and rules will continue to be valid, and they will reincarnate regularly.

This is actually just wishful thinking. After all, Bitcoin has only just appeared for twelve years, and it has attracted too much attention and sought after because of its amazing growth. The four endings mentioned just now are actually possible.
the last choice would be the best outcome

because these are two different systems, they should complement and support each other. because it is clear that each of them has their own weaknesses, that's where they give each other support to be able to fill the void.

Many countries we know are still unable to accept bitcoin as a legal medium of exchange, and only focus on fiat, because of course there are many obstacles that may occur. let bitcoin not have to play a role there, let fiat do it, but if where fiat is not able to do it, it can be ascertained that bitcoin can solve it. so there is continuity that can be done between them. this will obviously make bitcoin more welcome because it can solve the fiat problem.

bitcoin must be optimistic that later all will be able to accept the existence of bitcoin but it needs to be accepted well and there is mutual benefit because there are always differences to accept anything in every country.

I think the better result that bitcoin has created is the rate of adoption and use we have seen the last two years. Before this time, the rate of use wasn't this high and popularity has increased where we see that big buyers and institutional investors are coming in. This to me gives the explanation that people are a little confident to believe in bitcoin and hodl also. Hodling means there is confidence in what you are hodling dearly.

Just bitcoin becoming more relevant and positively known by people
Bitcoin was stereotypically related to illicit internet activities, but we all know that it's not.
Crypto transactions will be normalized and not deemed as something so complex to understand.

Based on what we have seen so far, the optimistic outlook is that bitcoin will serve as a store of value not just to individuals and institutions, but also to nation-states and government treasuries. In my opinion that's the realistic best case scenario.

More optimistic than that would be the situation where bitcoin is not only a store of value, but also used as an everyday currency and medium of exchange via higher-than-base-layer solutions... a world where fiat has decisively lost to bitcoin... where everything is priced in bitcoin and sats, where governments return to sound monetary policy because they can no longer print money like there is no tomorrow.

it can't be that easy to make a currency shift on a large scale. except as El Salvador did, it also requires steps that are not easy to adopt Bitcoin as a legal tender of exchange. and if as a currency then Bitcoin must have a control center. whereas Satoshi goal was not for that.

Return to its roots? I mean Bitcoin is still being used alternatively for payments these days. I am not sure how it was purely used back then, but I do not think that we would still describe the adoption of Bitcoin as "returning to its roots". It is already a tree and it gave a seed to a lot of coins in the crypto market, but many of them turned out to be just a wilted ones.
