Definitely Yes, If you see the evolution of money, the next best thing is Bitcoins. Popular, decentralized and not own by any group of people or government of a country. But the value of bitcoin is volatile still, hope it will be stable and increasing in future, that will cement the future of bitcoin.

There is no doubt that governments won't be quite happy with anonymous payments across the whole world, but they would be playing with fire it they tried to outright ban Bitcoin. The idea of creating their own cryptocurrency for the purpose of competing with Bitcoin looks stillborn to me or even detrimental to the government itself in the long run. People who are now using Bitcoin won't trust it anyway, but those who might use it (i.e. average people) will likely end up using Bitcoin at the end of the day...

Since governments will habitually destroy their version of Bitcoin just like they always do it with fiat

Maybe it's just how the government really works. They do not want anything to be out of control. Or to say the other way around, they want to control everything. If they couldn't, they would just destroy it instead.

may be can buy payment like buy food or other if bitcoin be legal , trust in yet my country bitcoin legal
i hope increase user bitcoin

I think we could say that, because bitcoin is the most used cryptocurrencies that is being use in the internet when buying some stuffs and other things that involves money. Since bitcoin's transaction is always fast depends on the blockchain actuallyl, if the blockchain is having many transaction to be processed then sending bitcoin to someone will take some to for about 10-30 minutes I guess. In the near future, I'm sure that bitcoin would be the money that we are all going to use.

Yeah bitcoin right now needs big adoption for itd direct using without having any dependance on fiat. Already bitcoin on its existence has made a new revolution in transaction and as a form of currency. This has laid the footstep for the digitaliztion and cashless economy around the world.

Bitcoin may be the new era of currency from virtual world but it owe it presence to blockchain which usher the new era of cryptocurrencies that now flooding the online markets and tradings.

I might refer Bitcoin as a new currency but certainly not "new era". I can consider bitcoin as a mode of payment rather than a currency because for it to be a major currency it must be accepted legally by a country and count Bitcoin as some form of secondary currency. But the chances are slim to none because Bitcoin cannot be controlled by anyone which means it can be hoarded or other things that can take advantage to others.

Money is what money does

Barring a few non-important countries (like Honduras or Zimbabwe), nowhere in the world a foreign currency (i.e. any foreign currency) is accepted legally. On the other hand, Bitcoin itself is officially considered as a foreign currency (i.e. just another foreign currency) in many countries. That pretty much tells us that to be a currency (or a major currency in your speak), it is not required to be accepted as a legal tender (since what accepting a currency legally comes down to) by some country. Do you know the national currency of, say, Paraguay, and how it is different from the currency of Uruguay?

yeah we know it, but over the times certainly bitcoin will be growing, and users will continue to grow, you'll see more and more local shops that will accept bitcoin, yeah it would be a bit time consuming
