Why do people think "crypto" is the same as "bitcoin"? For the love of god crypto is not equal to bitcoin... As a matter of fact mostly cryptocurrency means altcoins. So with that in mind the following statement “Believe me, the people who are creating cryptocurrencies are not thinking about the customer, they are thinking about themselves [...] I want to make my money by selling people things that are good for them, not things that are bad for them.”
is 100% correct. In fact I have said this at least a thousand times that altcoin creators are creating cryptocurrencies to make money by selling people vaporware. Take this token trend that has been going on ever since the biggest shitcoin of all time ethereum was created. From 2017 ICO scams to 2018 and 2019 IEO, STO scams to 2020 DeFi scam and finally 2021 NFT scams; They are all creating garbage and selling to to any idiot who buys them. They all think about one thing only: "to rip people off and fill their own pockets". The only absurdity about statements like this coming from these ancient people is that this is exactly what they have been doing for decades  |

Lol...now not China Ban btc fud lol now USA BAN BTC LOL...
The ban news is one of the oldest FUDs in bitcoin that it is now part and parcel of this world! I dare say people are going to be depressed if someday this FUD stopped  The FUDsters trying to buy bitcoin is just as old too. It just takes time for us to see the evidence. Same lame ....as xrp case
I'm not sure I understand what you are trying to say here by mentioning a centralized shitcoin. After 18 years working for goldman sachs in the banking industry. Gary Gensler has to be considered a somewhat reliable and credible source.
I disagree. Someone who has worked this long in the most corrupt banking system in the world is not reliable or credible at all, I don't care what he says even if he were correct. |

The real solution is to bypass captcha
This is a half solution though because it only solves the login issue not the cloudflare issue since cloudflare is not too kind to Tor and sometimes VPN users and keeps giving you a captcha to solve to just open the website (before even reaching the login page). |

This is a malicious website, do NOT ever use this site or recommend it to anyone. They have been intentionally suggesting extremely high fees for bitcoin transactions even during times when mempool is empty. For example right now the site claims that "The fastest and cheapest transaction fee is currently 102 satoshis/byte" whereas mempool is empty and there is only 0.2 vMB transactions that are paying 1+ satoshi/vbyte fees. So in other words this malicious site is reporting a fee that is 102 times higher than what you should be paying. Use http://mempool.space/ or https://jochen-hoenicke.de/queue/#BTC,24h,weight as it was suggested instead. |

I'm not sure about the fields, nor about their contents, so I need confirmation or correction !
Then you should start at the beginning and first learn what each of those fields mean and how they are encoded. https://developer.bitcoin.org/devguide/transactions.htmlhttps://developer.bitcoin.org/reference/transactions.html#raw-transaction-format scriptSig (empty) 01+00+ffffffff
Value of 1st UTXO (=14791 Satoshis) C739000000000000
You have 2 mistakes. 1. Your signature script is not empty, it is OP_0. You should set it to empty. That is why I said you should start at the beginning. Each script has a length (yours is 0x01 byte) followed by the script as bytes (your script is 0x00). To set it to empty you have to set the length to 0 and not have any extra bytes. 2. You changed the amount from 14800 to 14791. |

Argh, damn, that's a pity! I thought new nodes could e.g. get the first 200GB from a full node and the last 100GB from a pruned one, for example, what a bummer. Does anything speak against adding a mechanism that would allow to accomplish this?
I believe the arguments against letting the pruned node announce the number of blocks it has was a privacy related one. Implementation details have to be checked by someone who can read C++ better than I, but you can see the the BIP advises that to avoid fingerprinting pruned nodes shouldn't provide blocks deeper than 288 threshold https://github.com/bitcoin/bips/blob/master/bip-0159.mediawiki#counter-measures-for-peer-fingerprinting |

It makes you a technician, not an IT specialist or programmer. Usually one language is not enough, the more you know the better you are. And I don’t even talk about things like learning algorithms and other stuff you learn during computer science studies, but just the knowledge of differences between languages.
That’s true c# is a good choice in general, but it does not solve all problems. Maybe he will switch to building webpages? Or bash scripts?
I would say again- there is no one language for all, your problem decides what would be the best tool. But wide scope of education covers many subjects and - what is the most important- teach you how to think as a programmer, not just a dump copy-paste guy.
I agree and that's not what my argument was. I'm saying the approach was bad, I said you shouldn't start learning multiple languages or start learning a language that you aren't going to use. Instead you should start from a main language and put 100% focus on becoming an expert in that language. Then start learning other languages to achieve things that you can't do in the main language or things that can be done better in another language. |

Apart of languages like Turbo Pascal (  ) I think you may start with doing simple things in PHP. And later you will go into Java or C. Or C#. If you know one, you almost know others... I don't think this is a good approach. I find it best to start with a language from the start and focus on that completely. For example choose C# and stick to it from the beginning. You can learn the basics (doing simple things to understand how programming works) to advanced projects such as writing a full node for a cryptocurrency. This way your focus isn't divided among multiple languages where you know like 5 languages but all at a beginners level. Besides, some languages may never be useful like PHP and if you needed to (after mastering that one language) you can quickly learn that secondary language with your background. |

The basic gist is if you need to trust someone has kept their keys secure, send them some BTC.
Generally speaking the sender doesn't care about what the receiver is doing with their wallet. They could be using a very safe one or a custodial wallet (that doesn't let the balance stay in the address anyways) or a very insecure one. So the real question is what is the application of this project of yours since senders don't care about receiver's security? |

After SegWit the signer needs the amount of each input to be included during the signing operation when the hash is produced. It also became mandatory to prevent some exploits in hardware wallets that could lead to losses either through huge fees or even sending to a maliciously included output.
This is why you need to upgrade and use the new format with your hardware wallets.
I'd focus on figuring out why new version of Electrum couldn't be installed on your system. You could also use a live offline Linux to run the latest version a lot easier and even with more security compared to your closed source Mac OS!
Or you could do what Leo said and import your seed phrases from one of the hardware wallets into a new wallet in Electrum. But you'll need to figure out what derivation path your hardware wallet used.

It is simply not reliable and doesn't really support importing keys properly.
They've always allowed importing private keys ( https://support.blockchain.com/hc/en-us/articles/207746403-Wallets-Addresses) but the problem with importing was that they didn't let you choose the address type and they didn't support SegWit addresses. Not sure if this has changed or not though. You can also sweep or import. But of course it is not recommended to use a web wallet if you value your security and privacy. |

You're bringing up an interesting point here. I was always mostly discarding the idea of pruned nodes as helpful for the network, but one might actually prune for example to 150GB or 100GB; thus still serving new nodes almost half of the blockchain, which isn't unsubstantial and still relatively easy on hard disk space. Many games these days take 100GB, so I feel allocating 100 gigs to helping the Bitcoin network like '30%' utility, is better than nothing, if you don't have the space for a full blockchain copy.
Probably my pessmistic view of pruned nodes came from the idea of pruning down to like 5GB, but of course the limit can be set to anything you want.
Added benefit of e.g. keeping the last 100GB: You will probably have a copy of each block mined since you entered and owned BTC if you're still new to Bitcoin.
I may be wrong but the P2P protocol needs to change for this to work. For now the pruned node can only announce that they are pruned and not able to tell the other node how many blocks they have stored so any node that connects to a pruned node assumes they have the minimum number of blocks. This means it may not matter if you store 100 GB or 500 MB they won't ask for old blocks from your node. |

#bitcoinNotAffected
Seriously though where are all those who were pounding their chests saying "bitcoin follows stock market"? For the past week they have been dumping everything and bitcoin is still in the same channel as it has been.
On a shorter scale when for example S&P500 started dumping on 24 for 48 hours, bitcoin price went from $55k to $59k!

This show why sigwit transaction is faster because the witness is separate from the 1mb block of transaction.
SegWit transactions are not faster or slower, they have smaller weight compared to similar legacy transactions which means you end up paying lower fee in comparison. The witness is also not separate, it is part of the transaction and a part of each block in the maximum 4 MB weight. What will happens to the transaction with very low transaction fees if the ones with high transaction keep coming into the mempool after each one get confirm.
They remain in that nodes mempool until it is their turn to be confirmed or until the node drops it after a predefined period (default is 2 weeks) or they become invalid (like in case of double spending through RBF). |

Literary everything about this so called "exchange" is shady. - A weird uncommon name with a .xyz domain name that they probably got for free - Was registered recently so it is brand new - You heard about it from a random chick on tinder!!! - The name is similar to another company aka abusing their brand - Doesn't allow withdrawal - Asks for more deposit What else do you want to see to know it is a scam? |

He has gained enough popularity and with tweeting and making some good btc initiative like selling first tweet as nft to donate the money for charity causes.
I totally forgot about the NFT garbage he sold for a lot of money. It's funny how everyone who wants to make money through shittokens mentions "charities" too. I have already seen it 3 times among some celebrities who have sold various types of shittokens to the public for millions of dollars! |

He benefits from using this node of course he is going to be seriously making money. Having a node and an LN on it for Twitter users will be making a profit it's like owning a network of Billions of users. Scooping all the fees within the network is an endless flow of BTC without having to do mining. I'm not sure if he does it already but advertising on Twitter with BTC payments will make him more money.
You are confused about how things work. You can't make money by running a bitcoin node. In other words there is only security and privacy incentive to run a full node not monetary. As for LN nodes, the amount of fee they can earn is so minuscule that you can't call it "profit" or "making money" as you put it. It is a small incentive to handle transaction routing but not exactly a reward. The benefits Dorsey gains from his tweets involving bitcoin is popularity then he starts projects like his centralized decentralize exchange where he can use that popularity to attract customers and make money. |

one thing that i dont understand!
where is his all 1mil coins? is there anybody who saw his wallet balance? i know its a cold storage
how people say hes holding 1mil coin??
You have trouble understanding it because it is an absurd claim based on weak guesses at best. Basically many years ago someone hypothesized that certain bitcoin blocks looked to be following a "pattern" and based on that he concluded that they were all mined by Satoshi. Ever since then people have been claiming a lot of early blocks were mined by Satoshi hence the 1 million BTC balance sum. The funny thing is that from time to time an early adopter comes along and reveals that the early mined blocks were mined by them and moves the coins. Here you can see a lot of early block rewards that were already moved by their owners: https://blockchair.com/bitcoin/outputs?s=block_id(asc)&q=is_from_coinbase(true),is_spent(true)#f=is_spent,block_id,time,is_from_coinbase |

Metaverse are buiding on smart contracts so the role of BTC in Metaverse ecosystem is small.
In the sense that "metaverse" is the imaginary hypothetical part of the virtual internet, you are right bitcoin has little role in that part, useless tokens reside in fairyland. In real world on the other hand bitcoin is dominating. |

I have a web site and i want create a unique "Legacy" & "Nested SegWit" & "Native SegWit" address for every customer to send & receive bitcoin.
So i need a free api to handle this!
Using a third party like this is very risky specially when you are using one that is known to have many bugs. They could end up creating an invalid address for you and any coins sent to that address would be lost. It is best that you handle everything on your own. Generating an address from a public key is a pretty easy task too (it is a matter of computing a hash and doing a simple encoding). You can also watch those addresses using the Electrum protocol ( https://electrumx-spesmilo.readthedocs.io/en/latest/protocol.html). You can hire someone to code this all for you. |
