In my opinion, to achieve this process, you have to go through a lot, and most importantly a test of time. Now this segment is not stable and causes many doubts. Bitcoin is not legal in many countries of the world and does not work with governments. First you need to start cooperating, and then discuss global perspectives.

I believe it can however there will be a lot of consequences that need to be faced, such problem may acquire is lack of awareness and understanding of Bitcoin also the risk and volatility.

I think that's possible because with the stormy development of blockchain, it will be a solid foundation for the boom of bitcoin, more people will know it, and it will be used extensively on Around the world

It will not become a universal coin in the near future but will compete in the money we are accustomed to. The world economy was born for centuries and bitcoin which 10 years is very difficult to be close to them ! But he is I think !)

Yeah it can be and only time can tell. Although this should be tackle with our leaders in every country and the possibility can be achieve if we all can be united to support bitcoin for mass adoption. The rest could be history.

There is no denial in it that Bitcoin can become the universal currency because the population of internet users is growing rapidly  all over the world and the new generation can not think to live without it.They want everything on the internet so they will prefer the digital currency as well.

But it is used all over the world right? Bitcoin can be used to all types of transactions so you may not just see the possibility and application now but there it is. Whether illegally used or not, don't look at that part because even fiat money is being used illegally.

It may not be the universal currency in the future or slight but it can be use by everyone for almost everything.

It isn't hard if the adoption is vast, we didn't even expected it to be supported by some countries so impossible can be possible.

bro, the price of bitcoin is always rising and falling is the main reason why until now bitcoin cannot be adopted as a common currency for shopping in supermarkets. which causes the price of ups and downs because bitcoin is not backed up by real assets, I prefer cryptocurrency supported by real assets such as USD, Gold or Real Estate. this allows investors to feel safe with the amount of coins they hold

it can be currency for global if all human know about crypto, but for a while. it can be global currency if it can be use offline mode like fiat. everything have power and deficiency, so, use it in the right place. i think crypto can use without eliminating fiat. if some people want to pay in crypto is available, and fiat too
