For the record, the percentage of crypto holders globally is still 4% despite the increase in the societal value of crypto. Since it's an innovative digital currency, it will still be hard for some people to understand it.
I'm pretty sure that your estimate is inaccurate. According to
this report, the estimated global cryptocurrency adoption rate was around 6.8% in 2024, so I'm pretty sure that the figure is much higher in 2025 because we know more and more people are adopting cryptocurrencies over time because we can see a clear surge in the trend about cryptocurrencies around the world, more and more people are showing interest in trading and other means of making money through cryptocurrencies.
The market value of cryptocurrencies, even Bitcoin, doesn't show the growth of the industry, but it's the growth in the demand and popularity that shows how rapidly this industry is growing, and how more and more people are joining the revolution and realizing that cryptocurrencies are actually the future.
