Bitcoin would most likely be shunned by people and would most likely get irrelevant, investment wise. The tech wouldn't changed but it won't be as accepted as it is today. Bitcoin took few bull market to prove itself that it is a good investment and the tech behind it is worth the try. Bitcoin would certainly wouldn't reach the same, adoption wise but I personally think that it would take less years to be known to people and use it.
People are becoming sensitive now regarding to the investments they are taking as the economy is really bad in 2026, if bitcoin was invented in 2026, I doubt that many would risk their money on something new that doesn't prove anything.
bottom line, nothing would fundamentally change if bitcoin launched this year instead of 2009.
it'd still get doubted and written off by the crowd, sit through the volatility and spend years building up before earning the status it has now.
bitcoin got to where it is through years of development and by proving its value over time, not simply because it came along at a convenient time when ai was not mainstream as it is today.
sure , the backdrop might be different, but any new tech still has to earn trust to get adopted, and trust takes time .
There's no changes at all will happen, despite of having good technological updates happening in this year.
Since if Bitcoin will be created nowadays. I also think we might going to see similar situation, just like what happen on year 2009. We cannot easily win the trust of people, expect that people will still doubt about it.
The biggest challenges is if this will still became relevant. Because I think Bitcoin might get out of placed and will be dominated by government created e currencies and regulated platforms.
That's why its good that Bitcoin came out first and succeed. Before the other government controlled digital currencies exist.
