Many research studies show the cryptocurrencies are about to boom in the next years.
A growing number of businesses adopt bitcoin as a payment method, so I do believe we are witnessing a financial revolution.
It is especially important to note that 1/3 of people in the US aged 18-29 in the US have bitcoin and 1/2 of 18-35 years old state they are willing to invest in bitcoin.
Recent studies show that there are 300+ Million crypto users in the world, representing 3,8% of world’s population -
https://bitcoincasinowiz.com/blog/cryptocurrency-statistics/So it's a bit early to say that bitcoin can become a global currency but the crypto adoption is growing each year.
Are these studies real? I mean, how can they have calculated 300+ million crypto users? This means every 25th person on earth is a crypto user (I've googled world population -
around 8 billions). If I ask 26 my colleagues, I doubt that there will be a crypto users besides me. I would believe that there are 300 million crypto addresses, but not users. And I would not call a person, that has created a wallet as a user. Because, for example, I've tried smoking a cigarette, when I was much younger and in a company of smokers, but that does not make me a smoker.
P.S. And you have copied a bit wrong info. 3.8% is the percentage of Bitcoin owners from whole worlds population.
