I think https://btcpayserver.org/ might work for you. They are a better alternative to bitpay, as they are open source and accept segwit, and no forced kyc. |

An ever simpler solution is to split the seed between family members.
Give the passphrase to one and the 24 words to another, for example.
I don't like the idea to give access to my funds to someone else, so I think this is a nice solution, as only together both could get it.

In other words, why the AIS-31 compliant true random number generator (TRNG) generates a more random 256bit number rather than physical coin fliped 256 times?
I do not understand the limitations on AIS-31 compliant. Maybe someone who has more knowledge can help us better ( i would move this topic to technical discussion board for better inputs from community and less yobit spammers). But there are limitations on randomness of flipping a coin over and over again. 1 - muscular memory - i don't know if that expression is correct, I am talking about you doing the exactly same movement 256 times is not totally random. Your movement may not be 50-50, but 30-70, as it is the same over and over again. Maybe if you asked to different 256 people flip the coin once, it would have a better randomness. 2 - coin may have not be completely balanced, which could also lead to biased results (not 50-50). But anyway, as I said before, I think it is enough randomness for a priavate key generation. Don't know if it is better or not than AIS-31. But flipping a coin is not perfectly random imo. |

Do all coins need to start on these lower tier exchanges and work their way up? Aside from some of the obvious red flags is there anything to be on the lookout for when these are trading on their current exchange?
No. Good projects usually pay to be listed in a good exchange or good (or at least reputable) exchanges make some effort to list those projects. Being listed in a shady exchange is a bad sign of the project. As you are a newbie in the ecosystem, I wouldn't recommend start with a new created token. A 100% BTC portfolio will perform better than 90% of the portfolios out there. If you get good and reputable altcoins, such as top10 (eth, xrp, ltc, etc), they are also better than most portfolios. You are on the most risk and dangerous area, small cap tokens. Those coins are 90% scams, pyramids, ponzi, or just managed by incompetent people, or, sometimes, they are just unsuccesful to implement the project. A very small % survive,and even those are most of the time pump and dump and usually perform worse than btc. Take a look at BAT, for example. Good project, but losing value against BTC for years. |

Can you explain the algorithm and the process of private key generation by a hardware wallet (ley's say by Ledger)?
Ledger nano does not generate private keys, but a BIP 39 24 word mnemonic seed. Different from what you are doing, because generating private keys directly (however, this allows you to create just one address) I was able to find this information regarding randomness of the process (i think this is what you are looking for) Here’s how a BIP 39 24-word mnemonic seed is generated: The device generates a sequence of 256 random bits using the true random number generator (TRNG) built into the device’s Secure Element. The first 8 bits of the SHA-256 hash of the initial 256 bits is appended to the end, giving us 264 bits. All 264 bits are split into 24 groups of 11 bits. Each group of 11 bits is interpreted as a number in the range 0 - 2047, which serves as an index to the BIP 39 wordlist, giving us 24 words. https://ledger.readthedocs.io/en/latest/background/master_seed.htmlIf you think their entropy is not good enough, you can also add a passphrase to your seed, it will add an additional entropy to your private keys generation. |

Not sure if it's the safest way to generate a private key, but it's definetly the most fun way to do something like that.
If you generate 256 bit of your private key flipping a coin, you can 100% be sure that all your 256 bits are absolutely random. If you generate a private key with the help of some software/wallet/other service, you can not be sure in their random algorythm. In some cases they also could be pseudorandom, generating the predefined keys within the predefined range (even if you use them offline). I don't agree that the results are absolutely random. The coin weight might be a little biased, and you may have some muscular memory also which may lead to less randomness. Ofc this it is enough random for a private key generationg...... But I believe that are some better computer-based methods. I still think the most secure way of generating a private key is through a hardware wallet. However, for educational purposes, this flipping method is amazing. |

Hey guys,
We have the 10th anniversary art competition running and it's great. People already took the pencils, brushes and crayons out but why don't we make the same competition and finally get our logo, because as far as I know we do not have an official one.
It will be a great 10th anniversary gift.
As far as I know this is the official logo. This icon is displayed I all bitcointalk pages, on the top of the browser also called favicon https://bitcointalk.org/favicon.ico This is the fist bitcoin logo, created by Satoshi |

I thought I would see if I could build a passive income from free or almost free, camera equipment.
Jet Cash, are you sure you can sell photos to shutterstock with cheap equipment? I mean, those photos are very high quality and resolution, colors, etc. They are even better than those free websites like pexels and pixabay, which are very good too. I don't use cameras since smartphones showed up, but my smartphone cannot make good resolution photos like shutterstock require The project is aimed at helping members to create images that can be submitted to sites such as Shutter Stock [...]
Are there stock photo sites that pay their members in Bitcoin? I haven't keep track of stock photo sites for a while, but e.g. Shutter Stock seems to only support payout using the likes of PayPal and Skrill [1] (And I'm honestly surprised that Skrill is even supported, it feels like yesterday that having to deal with cheques was more or less standard). [1] https://www.shutterstock.com/contributorsupport/articles/kbat02/000006593I think this could be easily solved. Jet Cash can sell to shutterstock, receive in fiat, convert to btc, and pay for those members in btc. |

Even if you check part of the pasted Bitcoin address, chances are the first few characters are the same, and you still won't notice the address was changed.
Hey LoyceV, Personally I think it is very unlikely that few characters are the same. Maybe 2-3, but if you check also the last 2-3, or about 5, that's almost impossible to happen. The attacker would have to ninja-mine vanity addresses for that. The victims of this attack mostly don't even check the address. I think that even the address type may be different in most cases (legacy/segwit/nested segwit) How to prevent this1. Don't use Windows, but we both know you're not going to change that. I won't change this lol Never had any problem with windows... and I use computer at lot at work, where I can change my OS =D I think people bash windows too much, if you have safe online habits and take basic precautions, you are fine... Certainly I need to learn more about Linux |

Trading is brutal.
Predictions are wrong most of the time, and bitcoin make many unexpected movements.
Unless you study TA a lot, I don't think it is worth.
On the other hand , bitcoin's price increase a lot this easier, from 3k to 13 at peak, and now at 8.
Holding is still one of the most safe and profitable strategies, like most good assets.
Just buy some every month to dolar average it. That's my strategy

I have question about this, once you just created a bitcoin wallet, either it's legacy or P2SH or even bech32. You can still able to receive or create a receiving address any of those address types?
Because I noticed in my trezor wallet, when I tried to use it with mycelium wallet, you can select any address type you want, either legacy address/P2SH address or bech32 address.
Depends on the wallet. In Electrum you have to creatae a new wallet (even if you use the same seed) to change the derivation path (which is what the addresses type are, a different derivation path) However, in coinomi for example, you can use all 3 addresses type in the se wallet. You can use in funds from 2 of them in the same transaction and receive the change in another, for example. So, it depends on which wallet you are using with your trezor device. |
|
|
|
the easiest and quickest way to do it would be to set up an electrum wallet (standard wallet > create a new seed > legacy) which you can use to receive from non-segwit wallets. from there, you can send the coins to your native segwit hardware wallet.
Better than legacy is to use P2SH which are compatible segwit addresses, like a transitional address. They offer lower fees and are compatible with all old software. They start with 3. |

The advantage of bitcoin's pseudo-anonymity. You can stay anonymous as long as you you know what you're doing.
If 6 and 7 isn't an exchange as well, chances are, probably some custody holding wallet like probably from Barry Silbert's Grayscale. Anyway, don't spend too much time guessing and trying to find who these wallets belong too as your time is better spent doing something else more productive.
YeS. It is a waste of time trying to guess, and most probably all those Wallets are from exchange or another similar custodial service, as hardly one person would hold so much BTC. |

should I keep the native segwit wallet?
edit - what is a good standard wallet i should use to send to my ledger
You can use segwit compatible (which starts with 3). You will be already saving in fees, and it is compatible with every wallet. You will save more in fees using native segwit (bc1), but there are some incompatibilities. In your case, as a newbie, I would recommend using compatible segwit. Easier . |

You need to be careful when splitting your bch/bsv coins , as they do not have replay protection between each other. So you need to be careful otherwise you may lose your coins. Check this guide from coinomi (the best wallet to deal with shitcoins) https://coinomi.freshdesk.com/support/solutions/articles/29000026274-bch-abc-bsv-fork-information-splittingAbout replay protection: There is no replay protection between the BCH (ABC) and the BSV chains. This means that, unless you properly "split" your coins, transactions you make with one of those coins will also be made on the other. Sending unsplit BCH will result in the same amount of BSV being sent to the same address (and vice-versa). The receiving wallet may not be prepared to accept BSV into their address, so there is a possibility of loss of BSV coins. This is not an issue specific to Coinomi, as any other wallet you use is under the same risk. How to split coins: Splitting is only necessary if you had a positive BCH balance on November 15th 2018. If you received either BCH or BSV after that date, they are most likely already split. Receive a new deposit into your BCH wallet of BCH that is already split. Any value will work, however small. The easiest way is to receive BCH from an exchange. After transaction from (1) is confirmed, open the BCH wallet and copy your current BCH "receive" address On that same BCH wallet, go to the "send" section and send your full BCH balance to it. Done. This should be enough for your coins to be split. This process only has to be done once. After your coins are split, they are split forever, and further deposits you receive will also most likely already be split. |

Fortunately, this is a mistake that can be easily corrected just by selling BSV and investing in BTC.
It can easily correct once he makes a proper research and decides to change his investment plan. The problem is that it is very hard to find accurate information regarding cryptocurrencies. We see so many bullshit regarding scaling, quantum superiority, faketoshi, bitcoin old tech, etc etc that it is very hard for some people to stay away from all those scams. Even bitcointalk became a place for those stupid ideas, although here we can find also people who "show the light" to newbies |

Listing on a Top exchange is not a free job its obvious that they do charge you. Listing on a major exchange costs, sure, but there are plenty of exchanges out there which will list tokens for minimal costs or even free. Now thinking on the other hand the spam project gets a website done, whitepaper, content, promotion, listing blah blah blah and all of it comes for a cost. All of this can be done for free. Websites, whitepaper, and content can all (and often are) plagiarized or copied from various places. Promotion is easy - you just pay people in your new token that you just created out of thin air. Spammers will work for any old piece of trash, and doesn't cost the scammers a cent. One would spam only if they are getting profit, right? As I said above, you can create, launch, advertise, and list a scam for essentially free. It only takes a couple of idiots to buy these tokens and the scammers have made a profit on their time. Just image how many investor might be there getting chopped with such spam blades. There is no end to people who will believe any old rubbish are easily parted with their money. I believe all those problems can be summarized in one sentence: invertors and scammers looking for easy money. That's what our ecosystem became. Lots of people looking for 10000% gains without any effort (as if holding BTC for 5years was effortless) Now everyone is just looking for the next pump coin... |

If you are really willing to pay in btc, just announce in service board and you will get mre than 100 replies in no time.
Too many people looking for BTC here

I would say that the biggest bitcoin or maybe even the entire blockchain tech. problem is irreversibility of transactions.
If you want reversible transactions, censorship or centralization, just use visa. Bank system can reverse transactions and even give you a negative balance. This is not something good but something bad. Would you like to get paid, send your product, then the owner of the centralized network decide to reverse your transaction? Ethereum transactions were reversed in the past.. but that's not good |
