How would two different wallets agree on the IDs of the outputs when they construct their transactions? If the IDs are set when the transaction is included in a block, then how would an output that is not yet in a block be referenced?

None of those accurately depict a block chain. I suggest something like this:  |

Oh, oh, oh! How much time you've spent building a time machine? Are you traveling back in time from 2025 sending us a warning?
Nice try creating FUD mate. Bitcoin and other cryptocurrencies are here to stay no matter what. They are not going anywhere. Yes, we knew that US are imposing strict laws in cryptocurrency nowadays. However, they can only regulate it and not means of putting them out entirely because it's decentralized. They can't stop it.
I made a simple prediction and it is not FUD. You are free to disagree and state your own prediction. Whether or not the ban is 100% successful is not part of my prediction. Just as the illegal drug economy has continued despite its ban, the use of non-regulated currencies could also survive, though I believe the ban in the U.S. will be devastating. |

Thanks to everyone for their suggestions. Sorry for the delay, I thought I'd receive email updates to my post, but I didn't.
I managed to gain access to my coins. This is the route I followed. 1. Tried the BIP-39 seed option, that resulted in getting into my wallet, but nothing was there. 2. Accessed the application data from my backup. 3. Copied the wallet from there and placed it in the wallets folder on my PC and chose to replace the existing folder.
Since you were able to recover your wallet, but unable to use your seed to do so, I strongly suggest that you find out why your seed did not work. Electrum can display your seed, so I would would first compare that to what you wrote down. If they match, then I would try to restore your wallet on a different machine. |

I'm kind of scared holding the coins myself, I'm not very good with computers and security. I think a billion dollar company with expensive security will be a lot safer.
While bitcoins at Coinbase are fairly secure, there are still major risks: 1. A hacker could get your Coinbase password through a variety of methods and withdraw your bitcoins. Other than major exchange hacks, that is how most bitcoins are stolen. 2. Coinbase could freeze or confiscate your bitcoins. That happens more than you think. If you feel unsure about holding your bitcoins in your own wallet, try holding just a portion for now. You can move the rest to your wallet later when you feel more confident. |

If someone found the first six words of my electrum seed is it still safe or do you guys think I should change to a new wallet?
With the first 6 words known, there are at most 2 62 (about 4,000,000,000,000,000,000) seeds to guess. A PC that can check 1 billion seeds per second is guaranteed to find your seed in less than 120 years. While that may seem like a safe period of time, a sufficiently motivated attacker could acquire 1000x more processing power (for example) and crack your seed in less than a month. |

Or you could just connect the dots...Wikileaks...Bitcoin Blockchain...Silk Road Operations...
Wikileaks and BTC blockchain... how are they connected? How wikileaks was first involved in bitcoin At the time satoshi disappeared, wikileaks announced it was using bitcoin as paypal had terminated their account Satoshi did not want any undue attention and disappeared I don't think he was asking you to use the words "satoshi" and "wikileaks" in the same sentence. I think he was asking you to describe the actual connection between them.  I do not think you really know what you are talking about. If you did, you might have told us that both Satoshi and Julian Assange were members of the cypherpunks mailing list. |

It's not necessarily bad, but it could mislead the rest of the network into thinking, "oh well, we have enough nodes, I will not bother setting one myself". We want to ideally have 1 node per person (and many people running nodes), this strengthens the network. 1000000 nodes in the hands of a couple of corporations is less secure than 1000 nodes spread all over the world, by individual parties that don't know each other.
If a single person has a ton of nodes, that is a single point of failure, and you want to avoid single point of failures in decentralized networks.
But a single person running multiple nodes is no more of a single point of failure than a single person running one node. |

correct me if im wrong base on what i have read...blockchain connects one thing to another...my question is what if it was hacked or it was bugged? do all the informations were safe or will it be sustained?
Cryptography, which is just math, is used to prove the validity of a block chain. It can't be hacked or bugged unless the cryptography is broken. |

Therefore, Bitcoin currently produces MORE THAN 343 tons of carbon per hour!!!!
The oceans are become very polluted with carbonic acid and it is killing coral all over the planet. Bitcoin is killing our ocean.
Proof of work is an environmental disaster. We must stop now!!!
The real culprit is burning carbon to produce electricity. That is what we must stop doing. |

20k$ dumped to 6K$ was difficult but happened, 6k$ to 500$ is very easy soon will be worthless, So Why Some People Dont Believe BTC is SCAM?
A falling price does not make it a scam. The price of an Amazon.com share went from $105 in 1999 to $8 in 2001. Is Amazon.com a scam? |

It's a fallacy to think money can be created from nothing
What are euros created from, then? |

In both mining and brute-forcing private keys, you are generating 256-bit numbers in the hope of finding one that fits a criteria. If the criteria is met, there is a reward. You can consider the effectiveness of brute-forcing private keys in terms of mining.
There are currently 22,268,987 addresses holding an average of 0.76 BTC each. The chances of finding one of 22M addresses out of 2160 possible addresses is equivalent to a target of 0x000000000000000000000000000000000153CC3B000000000000000000000000 (assuming my math is correct).
That target corresponds to a difficulty of 1,764,330,921,064,039,848,434,241,513,961,029,632. If you compare that to the current difficulty of 5,363,678,461,481 and consider that the reward is only 0.76 BTC compared to 12.5 BTC, you will see that searching for addresses with a balance is incredibly inefficient compared to mining.

Some terminology clarifications: - Wallet: Contains private keys. It also describes the software that accesses the bitcoin network and maintains the addresses and keys that it controls.
- Seed (or recovery phrase): used by the wallet to generate all its private keys.
- Private Key: Used to access bitcoins at the address associated with it.
- Public key: Derived from a private key and used internally by the wallet.
- Address: In simplest terms, it holds bitcoins. It is derived from a private key (through an intermediate public key).
Frequent confusions: - An address is not a wallet.
- A seed is not a private key.
- An address is not a public key.

The title is misleading. Not every coin is an ICO. The list includes hundreds of coins that are not ICOs.

I heard that banks want to be involved with bitcoin but they can't since the price of bitcoin is so volatile. As a result the fall in bitcoin price is a way of ensuring that it becomes stable so that banks can work with it. How true is this?
It is not true, or it is at most extremely exaggerated. Nobody can control bitcoin prices with any kind of certainty and with no risk. |
