Here is a few things I still don't understand about Bitcon:

  • MultiSig: as far as I know, It is an address owned by at least 3 persons and to make a transaction, at least 2 people need to sign something.
  • Proof of Work
  • peer-to-peer
  • Bounties on BitcoinTalk

Not exactly. You can choose any number of participants from 2 to 15 and choose how many signatures are needed, from 1 to 15. You are talking about 2-of-3 multisig, but any M-of-N where M is between 1 and 15 and N is between 2 and 15 and M<=N is possible.

Quote
Proof of Work
You have one-way hashing function. It is called SHA-256. You can create some data, hash it and get some hexadecimal number. If you keep changing that data and computing these hashes, you will get many different numbers. Sooner or later, you will get something that is below some number called the target (that is calculated from the difficulty). To verify it, you only need to get that data, run SHA-256 once (actually twice, because we use double SHA-256) and you can easily check if it is correct.

Quote
peer-to-peer
It means that there is no central server in the network. There is no for example single WWW site like in a bank where you can log in, manage your funds and log out. It is decentralized. It means you can contact directly with the recipient and send him a transaction.

Bounties on BitcoinTalk
There are merit points below activity if you check any user account. I don't care about such points, but other people can probably explain how such merit points work, what they are used for, which rank you can get for what, etc.

Whenever you want to understand a concept about bitcoin, the Bitcoin Wiki and Developer Documentation are your friends. For your particular questions, your answers can be found in these pages which have a more detailed explanation than what I can write.

Multisig: https://en.bitcoin.it/wiki/Multisignature
Proof of work: https://en.bitcoin.it/wiki/Proof_of_work
Peer-to-peer: https://developer.bitcoin.org/reference/p2p_networking.html

  • Bounties on BitcoinTalk

I don't follow bounties so I can only give you a basic answer (and it's kinda off-topic for this board too): Certain organizations hire users for a tiny amount of money to promote their projects through social media and wearing bitcointalk signatures and avatars.

Not exactly. You can choose any number of participants from 2 to 15 and choose how many signatures are needed, from 1 to 15. You are talking about 2-of-3 multisig, but any M-of-N where M is between 1 and 15 and N is between 2 and 15 and M<=N is possible.
M and N can both be as small as zero meaning no signature is required and in 0of0 no public key is included in it. This is pointless but it is possible.
Additionally the maximum number of keys in this setting depends on where the script is placed and also depends on the type (hence size) of the public key.
If the script is used as redeem script and pubkeys are compressed the maximum is 15 but if they are uncompressed it is 7. This is due to limit on size of the data that can be pushed to the stack (here the redeem script) to maximum of 520 bytes.
If the script is used in pubkey script itself (raw multisig) then the number can go as high as 20.

P.S. Standard rules will prevent some of these combinations.

Bounties on BitcoinTalk

Good explanation for the previous questions, but you didn't really offer much insights about bounties in your reply.  

When it comes to bounties, most of the altcoin bounties are posted here. The thing to remember is that many of these are either scams, they will never amount to anything, and in some cases bounty hunters wont get paid. It is a rotten pond, but if you have the time and knowledge, you can might still get lucky and fish out something useful.

To make any money from a bounty, the project must receive significant investments. It's from those funds that the bounty rewards are paid out, and the projects usually do that in their native tokens or new altcoins. It's very rare to see a new project pay their customers in bitcoin or established altcoins. The token you receive will only have a value if it gets listed on a crypto exchange, has the needed liquidity, doesn't get dumped by big bag holders and developers, and has a use case. If all those conditions are met, you can exchange the new token for bitcoin (or whatever other trading pair is available on exchanges), and that is how you make profit from bounties. All this is just theory though as most of these 'projects' have no future and are outright scams.

Signature campaigns are different. They can also offer payments in new tokens, but many members opt to advertise for casinos or other bitcoin-related services that pay its users in bitcoin. You will find this type of campaigns in the Services section. To be considered for a bitcoin signature campaign, you need an account of Member rank or above, and have a good post history.

I can help you by answering the last question about the Bitcointalk bounty. I want to note right away that I have not seen bounty campaigns that pay in BTC, but maybe they exist. By themselves, bounties on Bitcointalk are advertising projects through which one or another crypto project, platform is promoted and for participation in which you can receive a small reward. Often this reward is paid in crypto project tokens or coins, very rarely in ETH, Tron, USDT. To receive a reward, you will need to complete certain tasks related to advertising on social networks, writing videos, articles or other tasks.
