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.

Lmao... so they just openly perjured themselves by admitting they have the private keys to some of the stolen Bitcoin...? good job Ira. This is exactly what CSW has been waiting for. Now he'll drop proof of his ownership with public documents. HONEYPOT.

Theoretically, if there was a vulnerability making private keys derivable from public keys would Bitcoin be doomed?

I'm trying to understand how Bitcoin would respond. Would it find a new way or would that be impossible? In the event that someone could break elliptical curve private public key encryption.

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

Done. Thanks, dmar198 !

This question has already been blocked as an off-topic one and marked as "altcoin" category. WHY? It's about Bitcoin. Are the admins incompetent?

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.

I'd just send the first three for now. Keep in mind that the Buyer can simply return the coins and not pay if not satisfied with coins delivered. The Seller would then send another tranche satisfactory to the Buyer.

Lets say they upgrade bitcoin will my public and private key still work

it depends on the upgrade and the reason for that upgrade.
99.99% chance is that all the changes that are made to bitcoin will not concern the way key pairs work and it will remain backward compatible which means the keys you create in 2009, 2010,...2018,... will still work in 2025,...

but there is a tiny chance that some day in the future we find a weakness in ECC and decide we need to move to a new cryptography method for key pairs. in which case the old keys may become obsolete. but as i said this chance is nearly zero. but it is best to keep updated at least every year.

Is there an app that can batch generate Bitcoin addresses (public + private keys)

I was wondering if anyone was aware of a script or program that can batch create Bitcoin wallet addresses with public and private keys and output that? We're giving away some free cryptocurrency as part of an onboarding learning platform and would need to generate several hundred of these, then deposit a little amount of BTC into each.
Any help is much appreciated!
