No, Bitcoin cannot destroy altcoins. Altcoins are alternative cryptocurrencies to Bitcoin, and their existence is independent of Bitcoin. While the success or failure of a particular altcoin may be influenced by market factors and investor sentiment, it cannot be destroyed by Bitcoin.

The creator of Bitcoin is unknown. The identity of the person or group of people who created Bitcoin is a mystery, as they went by the pseudonym Satoshi Nakamoto. Bitcoin is a decentralized digital currency that is based on cryptography. It was created in 2009 by an unknown person or group of people using the pseudonym Satoshi Nakamoto. Unlike traditional currencies, which are issued by central banks, Bitcoin has no central authority or government backing, and its supply is controlled by an algorithm.

since then, the network has grown and evolved, and Bitcoin has become a popular and valuable digital currency.

It is unlikely that a digital dollar would pose a threat to bitcoin. While a digital dollar may provide some competition for bitcoin, the two are fundamentally different and serve different purposes. Bitcoin is a decentralized digital currency that operates independently of any government or central authority. A digital dollar, on the other hand, would likely be issued and controlled by the government, similar to how physical dollars are currently issued and controlled. As such, a digital dollar would not be a direct threat to the existence of bitcoin, but it could potentially compete with it for adoption as a means of digital payment.

There are several reasons why people may choose to keep money on their phone. One reason is convenience. With a mobile payment app or digital wallet, people can easily make payments and transfer money using their phone, which can be more convenient than carrying cash or using a physical debit or credit card.

I invested in cryptocurrency in March of this year for Experimental. What I understand is that you should not invest only by reading the post or by searching Google. I should learn market analysis. Or there is another way to understand the market?

It will affect for a certain time. Not for a long time. You search on google you can find Many developed countries banned bitcoin. Prices fell for some time. But now it's up again. Ban will good also for a certain time :p.BTC holders sold it for less price. And you can buy it at a lower price

There are two types of young people. One type wants to be rich in a short way. That's why they invest here without knowledge after the loss they said gambling don't go :p One type Come here for a better future. They want a better future. They learn  first then invest

Rich person promotes myself lie that lol  .You can not promote yourself like that. You break the rules of this forum

There is no relation between block and private keys.

But i can explain litlle about private key and public key
You know that you need a wallet to store your virtual coins. And just like a bank account, it has a unique address. It looks somewhat like this(15WrztREKezKUyfSrBwKAnNhq2k7Pnhp5U), depending on the cryptocurrency. It seems like a completely randomly generated a string of letters and numbers but in reality, there is a bit more going on. The first thing you need to know is how these
are created. Anyone can create a new wallet by generating a public and private key pair with a certain algorithm.In the case of Bitcoin or Ethereum that is via an elliptical curve digital signature algorithm.

That’s quite a mouthful, but the take away here is that the algorithm will spit out a private key and an associated public key. These keys are mathematically linked to each other. You can take the private key and derive the public key from it. But you cannot take the public key and turn it into the private one.

 These two keys serve a different purpose. The public key will become your wallet’s address, kind of like your bank account number. public keys can be shared with everyone And the private key is your way of proving that you are the owner of the wallet and thus that you can spend the money inside of it. Private keys must be kept to yourself.

It’s only limited by how fast your computer can generate key pairs. However, nobody will know about the existence of your wallet until it receives some coins.

There's been a lot of speculation about Bitcoin. It's been a crazy rollercoaster ride. But what exactly is the future of Bitcoin?

Bitcoin frees us from the power of banks to hold or freeze our accounts for whatever reason. Bitcoin allows us control over our finances, the way it should be. Bitcoin is the perfect fit for this digital age where technology is the new norm. If you need money, you can simply access it through your phone.

Bitcoin provides opportunity and financial inclusion for unbanked people. Bitcoin is already making a huge impact in the world. Schools in Africa are even being built with the help of crypto. Crypto is everywhere now

Now that's just one of the many opportunities that Bitcoin can bring. Just imagine a future where bitcoin is universally accepted. although bitcoin is just another “pump and dump” scheme. Maybe bitcoin will down after 1-2year then it will pump again it will break all past records.
