If you or someone think Bitcoin will be vanished over night, such kind people shouldn't invest Bitcoin in the first place since they still doesn't know what's Bitcoin, how's work, the security and the reason why you want to invest in Bitcoin.

There are a lot thread have explain about Bitcoin and some people creating thread about the possible way Bitcoin will dead in the future, just use search engine in this forum and read the other people replies.

Some keyword about this matter:
1. Quantum computing
2. Recession
3. Hashrate dropping
4. Huge amount Bitcoin moved
5. CEX and centralized entity bankrupt

No one really knew that Bitcoin could be as valuable as it is today from being so worthless that a large amount could only get you a slice of Pizza.
Furthermore, before the Bitcoin price reached the All Time High (ATH) at $69K which was reached on November 10, 2021, who would have thought it could drop back to $16K.

What we need to strengthen our knowledge about Bitcoin is the belief that Bitcoin is an asset that has a strong foundation even though a limited number of Bitcoins are created.
There is no special knowledge apart from that belief my friend.

The future of Bitcoin is bright in the next decade, but the world government might still be a threat in the long run. The coin has done well for itself in years and would see more adoptions afterwards. But there would always be an alternative that would want to displace it over time which would be the ulterior plan of the government to tap into the blockchain technology but in a more centralized manner, thereby waging war on the exiting ones later.

Aside from this, I see no threat to the future of Bitcoin in both the near and far terms.

Bitcoin has the potential to be an alternative payment tool and an asset with stable prices in the future. Some people hope that with the existence of blockchain and cryptography technology, Bitcoin can help address some security and privacy problems in the current payment system.

It is important to remember that although Bitcoin has the potential to be an efficient and secure payment tool, there are still many things that need to be learned and resolved before the technology can be widely used. As with anything new and emerging, there are still many unknowns and risks to consider.

Therefore, to understand and consider the potential risks and benefits before investing in Bitcoin or other cryptocurrency technology, it is advisable to consult with financial and technology experts or discuss in forums and seek information that can help you understand the risks and make the right decisions.

Nah, bitcoin wont go explode overnight just like that. It is well deep rooted asset now and its everywhere, those who have accessed, downloaded a wallet, surfed a chain, mining devices and framework around the globe and basically internet. There is no way this data will get deleted overnight and the fail safe coding was already done by the satoshi. That is why we have hundreds and thousands of confirmation of every transaction which means that much times it was checked and verified by the miners and it's being store in the nodes. Practically the database has been copied so many times that it is now next to impossible to delete or manipulate. Thus, it will keep running even I am in my corpse suit in 80 years from now. 

Even if you genuinely believe that Bitcoin will prevail hundred years later, there is nothing terrible about preparing for a short-term shakeout so that you can still live comfortably. At the end of the day, if your goal in investing/using Bitcoin is to be financially stable, then you should expect some ups and downs and prepare your plan. This is not limited to Bitcoin btw, golds, stocks other assets work the same. The key differences are timeframe and market maturity IMO.

I would say bitcoin is not going to alter the course of fiat usage neither it is gonna alter the minds of peeps using it. Bitcoin is just alternative if you want to be your own bank, if you want unquestionable store value then bitcoin has got your back.

However, it would be unrealistic to say that bitcoin will be trans generational kinda currency. Basically it misses many pieces to the puzzle. From its limited circulation to the complete understanding for common man and much more.

Please stop from comparing Bitcoin to a Ponzi scheme straight away. Both are essentially different from one another and are unrelated. Even if use of Bitcoin is still not very widespread, I remain optimistic about it. When individuals give up, bitcoin starts to grow. Therefore, the goal for Bitcoin is that it will develop further as a decentralized, digital money that offers a substitute for established fiat currencies. I believe cryptocurrencies like Bitcoin and others have the potential to be accepted everywhere as a form of payment and a store of value, giving users financial independence and freedom from centralized financial institutions.

It is too soon to tell because not even a generation has passed since bitcoin was created, I believe it has the potential to be an asset like that similar to what we see with gold today, but potential is not the same as being a reality, who knows what it may happen during the next decades which could change everything and then bitcoin is no longer the asset we thought it was, so like always we need to keep our eyes open and see how this market develops before we make any hasty conclusion.
