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.
