The future of cryptocurrency is a space that is saturated. The digital age is growing, the future of the crypto market will be a big step forward.
Oh yes, nothing is clear yet. Meanwhile, I believe that Bitcoin and the best altcoins will be used widely. Probably, it will never happen globally but we will see it for sure.
Bitcoin will globally popular rather it is already globally popular and that's why some countries want to improve this currency because they know bitcoin will give them more profit for their people, but some countries people faced many difficulties by their government because their banned bitcoin use in their country but their people still use bitcoin and also invest in bitcoin, so that's why bitcoin will more beneficial by its highly value and most of countries will accept it.
