Well considering the rate at which fiat and paper currencies are disappointing, bitcoin seems a good option, but even bitcoin is affected by price volatility, it would be a perfect fit if it is a stable coin, my opinion though
Governments all around the globe are currently trying to develop their own national digital currency and I guess in the future we will be transacting with these currencies wherever we go. Consider the case of China, in China most of the payments are processed by its own payment processors and mostly the Chinese people use digital methods of payment, they don't even have to type in the password for doing payments, their facial recognition software does its job perfectly. The future will definitely be governed by the digital currencies and bitcoin will also be one of those currencies.
Exactly, many of the government's want to launch their own coin rather than going for other coins which has already listed also many of them give prior to it because they feel like it's a secured one and probably better.
This digital payment system will work all over the globe very soon and I believe in most of the countries they will lift the crypto ban too.
I can't say anything about the crypto ban in different countries as this will be their personal choice whether to lift the ban or keep implementing it and I think that in the future due to the pressure from other countries and the taxes collected by the governments, those countries with a crypto ban in place will surely lift the ban or at least will think about it.
Definitely Yes! In future most of the transactions will be done digitally just like what we see in the science fiction movies it will become a reality and the society will become paperless in terms of using money.
