I don't even think it is that. Governments (meaning: politicians and central bankers) are against PoW simply because they don't understand it. They are reading the same sensationalist headlines about energy consumption that the rest of us see. These people aren't enthusiasts who take the time to actually educate themselves on Bitcoin and mining and PoW. They just read headlines about Bitcoin using X amount of energy and producing X amount of carbon and they don't never get beyond these surface level statistics. They don't understand the reason for the mining, and they don't understand that the people who are writing the articles or reports they are reading don't know anything more about PoW and Bitcoin mining than they themselves do.

PoW simply has an optics problem. If you don't know what you're talking about and you just look at the amount of energy it uses, yes it looks very bad. If you do know what you're talking about then you understand the reason for the energy use and why it is beneficial to society for a number of different reasons. Just like if you had no idea what computers did and how they helped society but all you knew was how much energy they used globally anyone (at least anyone who gives a damn about the environment and the well-being of society) would be outraged. It's just pure ignorance on the topic that causes people, politicians or anyone else, to hate PoW and think Bitcoin should switch to PoS. I mean the very fact that they believe Bitcoin CAN switch to PoS, or the fact that they think if Bitcoin doesn't then just another crypto CAN and SHOULD replace Bitcoin shows that they have zero specific knowledge on the topic of Bitcoin and Crypto.

I very much doubt there are many politicians or even central bankers that understand the difference between PoW and PoS other than one uses a lot of energy and the other doesn't. So I doubt much or any of the opposition to PoW is because governments want Bitcoin to be weaker through PoS. It's just the optics of the energy use that is the problem.

PoW doesn't have an energy problem. It has an optics problem. And because of that optics problem there is so much misinformation that has been spread about PoW, which makes it really easy to think PoW does have an energy problem. The answer to PoW's problem is simply educating the public and politicians about how PoW really works and why the claims that it is wasteful are nonsensical.

We are still a long way away from Bitcoin being accepted widely as a means of payment. Bitcoin absolutely is a currency, but it is a currency of choice, not forced like fiat currencies are.

Will it replace fiat? No that is unlikely, simply because governments enforce fiat, so it isn't the people's choice. Over time more and more people will choose Bitcoin as it becomes normalized and there is much less sensationalized misinformation about it.

But then it will be the world's alternate currency. Most people will continue to take their paychecks in fiat, but many of them will save in Bitcoin and occasionally spend their Bitcoin savings on things. While some people will adopt mostly a Bitcoin standard and only rarely use fiat or just have some fiat in the bank for special purposes.

Will it become the world currency, yes. Though it'll probably take 20 years for that to happen. But being the world currency doesn't mean fiat won't exist. Nations will continue to have their own currencies that are used on a daily basis, and Bitcoin will exist alongside all over them all over the world. But none of that can happen until the idea of Bitcoin stops being sensationalized. The fact that it has been so successful in its price appreciation has not just caused a lot of people to love Bitcoin, but it is the primary reason why so many misinformed people hate Bitcoin - due to jealousy, the feeling of missing out, the idea that nothing legal or safe or real can appreciate so much. Once people stop sensationalizing Bitcoin and everyone can just accept it for what it is - a decentralized sovereign digital currency with perfect hard money qualities - it can start to be accepted as a means of payment.

According to data available at https://bitnodes.io/ there are 54 Bitcoin reachable nodes in China. That means despite all pressure Chinese government still not able to ban bitcoin.
Bitcoin decentralization is ensured by thousands of nodes distributed worldwide and they only way bitcoin can be controlled is to take control of all these nodes, something technically not possible. Moreover, Bitcoin network will continue to operate as long as there is one node willing to run the bitcoin blockchain.

But that will never happen because the world is heterogeneous, I mean, looking at the countries that are dividing each other for the benefit of each country. They will never become 1 or combine into 1. Just comparing with our family members, we can see that we have never all had the same opinion, let alone a country of many different ethnic groups with different thoughts. So we don't need to worry about all of them coming together.

I have no doubt centralised exchanges are the government arm of Crypto currency regulatory body. They are good at nothing than taking and trading customers identity and funds  without their consent. You would be made to sign up for what you have no knowledge about when it happens, they would tell you that you gave consent to them for that just like the issue of one of the exchange that won a case whereby members could not access their funds as a result of the documents they signed and agreed to. I do not for once trust centralised exchange so therefore I do not leave my funds there. I stick to this phrase " not your keys, not your funds" because I do not want to hear the story that touches the heart any day.

^  What 'economic model'?  Are you talking about the supply?  Ok...  Yeah sure but think about this, if it's solely about the 'economic model', then why are there other coins that have limited supply, that's even more under 'serious development' than DOGE, have less market cap than DOGE?  It's all about the demand because it's the demand that dictates how high it goes.  And sure, DOGE's demand is the product of the hype behind the coin.  But then again almost everything in crypto has to do more about hype than anything else.  That's why my new thesis on how to make the most you can in the next bull market is all about coins with doge logos.  

All doges...  Tokens, NFT's, everything!

BNB, Binance Coin, is one heck of a cryptocurrency if you ask me. It's been killing it in the market and staying on top for a reason. People trust it, plain and simple. And why wouldn't they? Binance, the exchange platform backing it, has been working hard to make sure that BNB stays valuable. Plus, holding onto BNB can actually get you rewards! How cool is that?

Long term investment in BNB? No brainer, my friend. As long as Binance keeps up their reputation and stays committed to the growth of BNB, you'll be in good hands. Trust me, this coin won't just collapse like some other cryptocurrencies out there. BNB is in a league of its own with a system that sets it apart.

So, in conclusion, if you're thinking about investing in BNB, go for it! It's a solid choice with a promising future.

CBDC is not a stablecoin, so this comparison is identical to comparing the dollar with a stablecoin. CBDC is issued by the national bank and is another, high-tech form of money that will function alongside cash and non-cash forms of money. Accordingly, I will have more confidence in CBDC than in any existing stablecoin.

What you mean by bitcoin is here to strengthen the fiat currencies in the world if only they understand the coin and adopt it? In my opinion and opinion varies, Bitcoin is not here to become a world currency neither is it here to strengthen fiat currencies. Why would it want to strengthen fiat currency?

Bitcoin has come to be a great alternative to the fiat currencies and the present financial system and not to strengthen it.
Think about it, if it was here to strengthen and support the present traditional financial fiat system of payment, then governments of the world would love bitcoin and support it.

Altcoins aren't a single coin so there is no way that all of them will die but many of them are now dead because they are weak and scam. Good altcoins can suffer from a bearish market but being dead isn't the best way to call or term them during these times. You can't call something dead if they are still active and can recover by the time the bull season came in, and also it was the new coins who has more chances of dying because new coins usually don't have anything new to offer as almost all the ideas are already given by the old coins. New coins are only good for the hypes so we can still invest on them for short-term gains.

Totally agree, the government doesn't want to completely ban bitcoin, what they want is to control it. Banning bitcoin won't do them any favor, but if they can find a solution to control it, they will get a lot of benefits from it, especially the huge tax we will pay them. They always make threats to ban bitcoin but so far, they have not done that, they are just trying to buy time to find a way to control it. I believe there will be a lot of regulation for bitcoin and crypto this year, let's wait and see how it plays out.

All altcoins die every year until Bitcoin is resurrected. When Bitcoin is in a bear season, the market is also in a bear season. When the market is in a bear season, there is no altcoin that diverges positively from the market. This may be the simplest explanation for how the market works. Actually, there is no need to be pessimistic, but coins other than major altcoins are never safe.

Only bitcoin can be trusted to be the one avoiding inflation, not any altcoin. So with that logic you should always buy Bitcoin and not altcoins. Altcoins may bring your profits over the short term but there can only be that much and not more. In the long run they are going to go down and you will suffer for your decision.

Human nature of being greedy is fed by altcoins, there is not doubt about this. But even then we have to be careful about newly launched altcoins.

Truly people are more interested in Bitcoin but fear buying it because of its large buying price to get a whole number of Bitcoin.

I only use XRP to transfer funds due to its cheap transaction fees and its fast confirmation times. I haven't really thought about buying XRP for investment purposes, as it's a centralized coin controlled by a company and every aspect of its development is highly influenced by those within the company. Ripple Labs doesn't really listen to a lot of suggestions from its community, and that's scary because the community is the one responsible for posting value to the said coin.

Your guess might just be as good as mine, but one thing's for sure — it wouldn't be a major country like the US/UK/etc. A smaller country like Tonga(like you said) has a lot more incentive to take such risks compared to huge established countries.

Campaign paid

One exchange couldn't crash crypto forever.  Mt gox pretty much ran all crypto exchanges at least from a percentage base and crypto survived.  Back then when crypto was just some sort of fringe experiment still.  If that didn't kill off crypto, an exchange going upside now won't either.  Here's an idea...stop using exchanges as wallets!!

In a sane society, who are the government?, it is the people, the people of the society make up the government, the people are the ones who choose those we supposedly call the government, so ordinarily, the supposed government aren't supposed to be more powerful than the people that put them there, but the problem now is that we live in a world controlled by money, because this set of people we ourselves choose to serve u now are in control of our money, we automatically lose our authority over them, this is why they now have the power to choose for us what should we call money and what we should not..

Aside the above, money is what a group of people have chosen and attached a value to, not particularly the government, from the price of bitcoin today, it is evident that the people have chosen and attached good value to bitcoin, if we lived in a sane society, the debate whether bitcoin should be accepted as a money or not shouldn't even come up because from all indications, it is money already.

Paper money will not be eliminated. Although digitalization is a trend now and digital currency is very convenient, there are still many people who do not use smartphones. Many people still rely on paper money, and its use has become habitual.

Can government completely ban Bitcoin or not? To find answer to this question one must consult Bitcoin Whitepaper, on very first line we find this:

"A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution." Bitcoin Whitepaper

Bitcoin was designed from scratch to overcome limitations of existing financial system, where every transaction has to go through a central authority for approval. Since there is no central authority in Bitcoin then how can it be banned ? Go through Bitcoin whitepaper and we can find answer that why governments are againest it and why it cant be banned.
