Bitcoin uses cryptographic key "pairs"
There is a public address and a private key (long string of letters and numbers for each)
A simple way to understand it is a username(public address) and a password to allow sending money from that address(Private key do not share)
That is basically the gist right there.
Remember Bitcoin is a network so there are many many options from hundreds of vendors and open source projects to simplify the process and access the Bitcoin for you. These are called wallets. They manage your key pairs for you. To back up a wallet you write down a 24 word seed phrase(private do not share) this will allow you the leisure of not storing every single address you own and let the wallet store them for you. If your wallet is destroyed or lost this seed phrase is how you recover your coins. Only use trusted wallets that this sub can recommend you, use the search bar.
You can get Bitcoin by earning it. ORRR trading from an exchange. Depending on your country and local laws this could be various different places. But generally Kraken, Gemini, and Binance are the most popular.
Remember however, if your Bitcoin is not in your wallet or you do not have the key pairs it is in, then you do not own the Bitcoin. Keeping your Bitcoin on an exchange or another 3rd party is highly risky and vulnerable to hacks or the exchange just straight up stealing your funds or even government stealing your funds.
So: Not your keys not your coins.
Plus: Don't use Bitcoin "Doublers" or anyone claiming if you send them bitcoin they will send you back double.
Plus: Don't buy altcoins, ICOs, or get involved with defi.

What is bitcoin going to do to prevent quantum computers from generating private keys from public keys?

From what i understand Bitcoin uses a form of RSA to generate public keys and private keys. So when quantum computers gain enough qubits its going to be possible to extract your private key from your public key. Are there currently any proposals for changes to prevent this.
Im just interested in bitcoin so please correct me if im wrong about something

Of course I have read the theory (wiki, “double and add” algorithm, Elliptic Curve secp256k1 and so on ). It does not help actually. Only on this reason I made this post.
I have a specific question ! -- the SIMPLEST CASE, private key =1. Without common words, just step by step instruction.
Please make it clear finally.

Public/Private Keys: Are these unique to Bitcoin/Blockchain? Why cant it be used outside the blockchain context

I accidentally imported a public bitcoin address into the blockchain.com wallet. I didn't realize I was supposed to import the private key. Is there a remedy??

Greetings. Please see above. I know there is a warning on the blockchain.com site that says "Do not import a public bitcoin address. If you do, the address will be imported as watch only and you will not be able to use its funds."
I just messed up. What can I do??
Thanks

Bitcoin Blockchain Is Near Impossible To Hack - asymmetric encryption (Public & Private Keys)

If I want to store bitcoin (or any altcoin) securely offline, do I need both public and private key, or just the private key?

I've learnt a lot since I started, but just filling in the missing gaps of my knowledge. Recently found out that with Raiblocks, you only need to store the private key, and that will automatically generate the public key to store any amount of wealth.
I was wondering if Bitcoin, and other altcoins also worked like this. Do you only need to store the private key, and the associated public keys can be automatically generated from that?
