you also seem to not be aware that we have already using "state issued digital currencies" for decades. long before bitcoin was even created.
There are many people that don't realize that fact. The main difference between a CBDC ("central bank digital currency") and the current system is that a transaction goes through the central bank directly rather than being routed though the banking system. Like all the others have already said, CBDC will not kill bitcoin. It is just a way to make the inflation go at a normal pace, CBDC is a solution to inflation because of money printing and the expense of money printing ...
CBDC will not change inflation. It will not affect how a central bank prints money. A central bank could still print an unlimited amount of CBDC. |

Or put differently: (if not stated otherwise in the User Agreement and when asked) do exchanges have an obligation to provide you access to your private keys?
That question shows a misunderstanding of how custodians work. There is no such thing as "your private keys" at a custodian. An account may have a deposit address associated with it, but the bitcoins that are deposited at that address do not remain there. As for "not your keys, not your coins", I wouldn't take that too literally. All it means is that you do not have actual possession of any of the coins held by the custodian, regardless of whether or not you may have some legal claim to coins held by the custodian. |

Hi guys I am trying learn the relationship between 256 bit encryption and bitcoins addresses and private keys. I remember something ages ago which showed the bits (256) corresponding with the private key. Can someone point me in the direction of such a resource.
Thanks
You can find some good (but dated) step-by-step demos here: https://gobittest.appspot.com/ |

So, 1 million of addresses would be 165 million bytes which is equal with 165 megabytes. Pretty heavy csv file, my computer would crash if I opened it.
I see. You are really asking about how much space is needed to store a private key for every address. Since a private key is 256 bits (plus a checksum and an 8-bit prefix that we can assume is always 0x80), it requires 32 bytes. The space required to store a private key for every address is 32 x 2 160 bytes, or approximately 4.7x10 49 bytes. Assuming that you can store 200 bytes (1600 bites) in a nm 3, that means that the volume required is 235,000,000,000,000,000,000 m 3 ( 4.7x10 49 / 200 / 10 27 ). |

All private keys are 2256, but all addresses that can exist are 2160, which is an enormous difference. This means that there must be some address collisions.
An address is an encoding of a 1-byte network value plus a 20-byte hash, plus a checksum. So, the space needed to store an address is 21 bytes. Since there are 2 8 possible network values and 2 160 possible hashes, the amount of space needed to store all of the addresses is 21 x 2 168 bytes, or approximately 8x10 51 bytes. That's equivalent to 8,000,000,000,000,000,000,000,000,000,000,000,000,000 1 TB drives. However, it raises the question, why would you want to store every address, when any address can easily be generated? As for collisions... Yes. Each possible address can be derived from an average of 2 97 private keys, which is an extraordinarily small number compared to the 2 256 possible private keys. |

Hello Everyone I'm new here. I did some research about cryptocurrency exchange. I know very little about this topic. What should I do What do you suggest?I thought of investing to bitcoin for $100 to start before vote in usa. What do you guys think?
Is it wise? No. Gambling is not wise. |

The additional bitcoins you won are counted as income from gambling, so this is what I think you are supposed to do: 1. Gain in value of original bitcoins are counted as capital gains. 2. Value of bitcoins you won when you won them are counted as income from gambling. 3. Gain in value of the bitcoins you won since you won them are counted as capital gains. I'm not an expert on taxes. https://www.irs.gov/taxtopics/tc419 |

I would avoid applying ideas of morality to the words "honest" and "attack". Morality does not apply here. I also would like to point out that we have seen many examples showing that a "51% attack" is not necessarily fatal. That means that Bitcoin is much more susceptible to a 51% attack than people believe because the idea that the attacker loses everything is simply not true. But let's be on topic. Blockchains are NOT distributed systems. I haven't seen a post that tells me I'm wrong.
That's because you consider a system to be either distributed or not distributed, with nothing in between. I don't think any system could be considered distributed by your criteria. |

I am looking for some genuine and best methods to invest my BTC in.
The only places to invest BTC are lending sites like BlockFi.com(but watch out for scams). Everything else is either a scam or not really an investment of BTC. |

I sent an amount to an address and my transaction has as input multiple addresses of my wallet. As a result, most of the input addresses have a non-zero final balance after the transaction. Is this normal? I know that there is a security issue if you use an address as input and it still has a positive balance after the transaction. I have seen this topic explained by Antonopoulos but I don't know if it is an important security issue. Is there a way to make my used addresses to have 0 final balance?
When your wallet chooses inputs, it doesn't seem to consider addresses at all. If you want to ensure that an address has no balance after being used as an input, you should receive bitcoins at the address only once. |

Are there non custodial and decentralized coin mixers?
If not so, are they possible?
You are looking for wallets or services that support CoinJoin. Examples of that are the Wasabi wallet and JoinMarket. Just know that all mixers are noncustodial services...
For mixers, I'd say that deciding factor is how they generate those private keys and if (as well as HOW) they get rid of those private keys. I'd say it's all automated, and that would make it non-custodial exchange. If on other hand, they save those private keys somewhere or if someone can access them that would make it custodial exchange.
I was just thinking how mixer could get private key, I'm not doubting if chipmixer did not generate PK or not, I know private key is used to import bitcoin balance from one wallet to another, although mixers are not wallet rather, can it be possible to import bitcoin balance from chipmixer to another mixer using private key? I don't know if my question is appropriate.
all coin mixer is non custodian if they are not I think their objective is defeated because they are created to increase the security of crypto transaction and make the users to be more anonymous. Getting regulated means their operation is not going to provide users with more anonimity. Most of them exisiting today are created with faceless team
That's all nonsense. Mixers like ChipMixer are custodial and centralized. You send them coins and then they are supposed to send you coins. There have been plenty of scam mixers that just keep your coins. You must trust them with your coins. That makes them custodial. |

Learning about trading with cryptocurrency is good and also everyone is interested to learn about it. ...
I didn't bother to read the article, but I can tell you the most important thing to know about trading: most traders lose money. |

The Bitcoin protocol itself does not have that capability, however there is no reason why that functionality couldn't be implemented in a wallet.
|
|
|
|
Note that there is also currently a bug in the protocol's implementation which leads to an average block time of 599.7 seconds rather than the intended 600 seconds.
What bug is this? The only bug I am aware of skews things in the other direction. Although the retargetting period is every 2016 blocks, it only considers the time taken to mine the previous 2015 blocks, which would result in an average block time of 2 weeks/2015 = 600.3 seconds. That's the one. I got the math backwards. Thanks for the correction. |

What are the circumstances that we can reach those blocks in just a short period of time like not will reach in the approximately 4 years or it will more than?
The actual time between halvings depends on how much the hash rate changes. When the hash rate increases, the time between halvings is shorter. That is why the halvings so far were 32, 139, and 56 days early. Also, do we have any idea or basis why Satoshi Nakamoto decided that the block halving is scheduled in every 210,000 blocks?
I believe that the 4 years between halvings, the two weeks between difficulty adjustments, and ten minutes between blocks were chosen somewhat arbitrarily. Just become curious, because I saw an article about the upcoming US Election and Bitcoin.
Since the US election is held every 4 years which it is the same with the block halving event of Bitcoin.
Bitcoin was started in the year after the election. The first halving was in the same year but after the election, and the next two were before the election. In several years, the halving is likely to occur in the year before the election. The halvings do not occur on precise four-year intervals so they will not coincide with U.S. elections most of the time. |

Its essentially the first blockchain certificate of deposit and hex was given free to any btc holders that signed a message with their eth address.
It is not a "certificate of deposit". It is similar to a bank paying interest with beanie-babies instead of dollars. Hex is not a ponzi scheme. It is a sophisticated pump-and-dump. When the staked coins are air-dropped on November 19, they will be become worthless because nobody will have a reason to buy them. Anyone that is buying hex now is going to lose it all. |

I can login through the application. The problem is only on the computer.
Probably this: You could try removing cache on that browser you're using along with any add ons or plugins you might not be using. If it's happened multiple times with that site then it's probably something to do with your instance of it that's been cached or something.
