It will be good not to make use of https://bitcoinfees.earn.com/ for bitcoin fee estimation, it is not good as it is a very poor bitcoin fee estimator. For ease, you can try https://mempool.space/. 71.1 sat/vB is not a small fee, the mempool is at 31 sat/vbyte now, the transaction would have been confirmed already. How do i make sure i am using either of above to save on fees guys?
Clearly enough dkbit98 has differentiated the bitcoin addresses. To pay lowest fee, use native segwit (bc1). Nested segwit (3-prefix addresses) has low fee too native segwit has the lowest fee. But using Legacy (1 prefix addresses) has high fee, even more higher if the address is uncompressed legacy address. |

MurAll (PAINT) at $0.00399200 in your link above, having a marketcap of $38,384,559, also having a circulatory supply. This makes me think NFT can also work on trading the way normal coins are working, which means I can buy NFT or sell for trading purpose in which the price may increase or decrease depending on demand and supply? Christie's sell an NFT by digital artist Beeple for $69m recently, this sound like those Mona Lisa painted by though non fungible, this kind of NFT are not for such trading purpose like MurAll (PAINT) because it is bought by only one person? Which best article can I know the A-Z of NFT? Never mind my question if not correct, I do not know much about NFT. |

You do not need to know if hoarding merit has advantage or disadvantage to members or the forum itself, the fact still remains that merit system is perfectly working good even while there are not areas that are faulty in respect to merit system. You do not need to think about this than also making research, know about bitcoin, other crypto assets and other boards of this forum that interests you and make quality posts. Members hoarding merits or not, good quality posts will stand out and be merited.

However, ledger nano is safe, even though some of its software is not open source.
Just only ledger secure element is close source, all others are open source, that is why people still recommend ledger nano because only the way it is generating and storing seed phrase is close source, but very possible a close source secure element can have vulnerabilities that would predetermine generated seed phrase. Although not implying ledger nano is not safe, but implying better using what is completely open source in my opinion. |

Do most people here only have one hardware wallet or they have two or even three as extra ones?
People do say having more than one wallet can increase privacy but we should also know that securing 3 seed phrase is more risky than securing one. So, this depends on you, but if need two or more hardware wallet, it means you need to know how to protect your seed phrases. If you were to get a second hardware wallet, which would you choose?
I will choose open source wallet, Trezor precisely. Ledger nano is not also bad either but its secure element is close source. I know there is the nano ledger X but the one thing that bothers me is it uses a battery so that means after x amount of years, wouldn't it not work anymore?
Not your hardware wallet is most important, what is most important is your seed phrase. If you have your seed phrase, you have your wallet because you can use it to to recover back your wallet. I did hear trezor has some security issues where it was hackable but is it still true now?
Nothing wrong with Trezor, but use passphrase in addition to make it safer. If passphrase is not used and a hacker stole it, the hacker later can know your seed phrase after breaking into your wallet and use some no costly tools to extract out the seed phrase, but if strong passphrase is used in addition to the seed phrase, you are still safe in this case. As for me, I still prefer Trezor because it is completely open source. I know there is another trezor called trezor model T. So that is better than the regular trezor one?
It comes with larger screen, more features, support more cryptocurrencies but more costly. Of course if i buy a second hardware wallet, i would buy it directly from the sites and not a reseller like amazon or any other similar site.
Try all means to make sure you fill in details that will not reveal your identity, see what ledger data breach cause its users. I mean could a regular person who is very tech savy create their own hardware wallet or something?
Yes, but someone needs to be very careful not to make mistakes. You can even buy the hardware wallet parts and assemble it your self but getting the ready-made one is better. Wouldn't it be best to stick to the two main brands? Either ledger or trezor? I feel like any other brand... you don't know if you could trust it one hundred percent in terms of safety issue. Like which hardware wallets has people here talked about where its not secure etc? I see brands I never heard of and these cost even more than the nano ledger s and even X.
I prefer Trezor, but people do talk about Coldcard to be very secure also, it is open source and I like open source wallets but not easy to use like trezor and ledger nano. |

Private key produces a digital signature that makes it possible for a corresponding public key to spend through a digital finger print known as bitcoin addresses. My apologies for the derivation path, how would somebody go about finding the corresponding private key to a public key that was derived from an extended public key?
You need the private key, or seed phrase that can generate the private key. While creating a wallet, you will be given the seed phrase or private key. And as you meant extended public key, that means you created an HD wallet. You either need the seed phrase or the extended private key, or the private keys of the address(es) of your wallet the bitcoin is sent to. |

A seed phrase (what appears in your image) is a series of words used in HD wallets for generating numerous private keys.
In HD wallets, seed phrase generates the seed. Seed phrase represents entropy with 128 to 256 bits, this is used to generate seed with a longer bits (512 bits) through key-stretching function PBKDF2 using HMAC-SHA512. From the seed, the master private key and master chain code are generated through one-way-function HMAC-SHA512 while the master public key is generated from the master private key. Then, the master private key produces the child private key also through one-way-function HMAC-SHA512. What I just want to point out is that seed phrase do not generate the private keys directly, seed phrase generate the seed, the seed generates the master private key while the master private key generates numerous private keys. |

Although, before it is very unstoppable to stop bitcoin because it is decentralized, while people are now adopting it the more. Who are the people to stop it? The governments that have officials already having bitcoin, this makes it hard for bitcoin to be stopped in the developed country, while the developing and underdeveloped countries will follow. I see bitcoin as the world's currency in the future, not that it will be the only currency but will be the most powerful of all existing currencies. Also a potent asset to compete with gold which is the greatest asset in the world.
Bitcoin is unstoppable.

It surely does good, it's a solution for the block size limit,
Segwit makes use of weight to reduce transaction fee. Possibly because of the vbytes metric, it is a common misconception that segwit somehow makes transactions much smaller—but this is incorrect. A 300-byte transaction is 300 bytes on-disk and over-the-wire. Segwit just counts those bytes differently toward the maximum block size of 4M weight units.
The maximum size of a block in bytes is nearly equal in number to the maximum amount of block weight units, so 4M weight units allows a block of almost 4M bytes (4MB). This is not a somehow "made-up" size; the maximum block size is really almost 4MB on-disk and over-the-wire. However, this maximum can only be reached if the block is full of very weirdly-formatted transactions, so it should not usually be seen.
The typical size of a block depends on the make-up of transactions in that block. As of 2017, the average transaction make-up would lead to blocks with 4M weight units being about 2.3MB in size if all transactions were segwit transactions.
In wikipedia it says that SegWit was activated on block 477120, but who begun that?
I do not know much about consensus, experienced members about it will answer that. But what I know is that segwit transaction begins with miners supporting it activation, while majority supported it and makes the activation successful. Public key to private key reversal. (I've heard that it may be possible to do that with quantum computing and pollards kangaroo method)
Private key can not be reversed as it is a one way function. But you meant can it be brute forced through the use of quantum computing. According to what I learned, it is not early days quantum computers that can brute force the ECDSA, it will take time before this can happen, and before it will happen, there would have being layers of protection against quantum computing to brute-force bitcoin private key from public key. Finding collisions for RIPEMD-160 hashes. Are we sure that 2160 is strong enough? What if it becomes weak in the next 20-30 years?
Double hash/hash160 is used in a one-way-function to generate addresses from public key, it will be much harder for quantum computing to brute force private key from addresses. And know if this wants to become possible, before it becomes possible, there will be another layer added that will be impossible for quantum computing not to brute force the private key. |

Its quite surprising how far, and wide the ATMs have reached around the world. I've some some in foreign countries, as well as being in my home country. I'm never really seen the need to use one, over other more traditional ways, especially if you were to consider tampering, which occasionally can occur with non cryptocurrency ATMs. Personally, I prefer to purchase from an exchange, but I'm curious in this day, and age what would be the benefit for a cryptocurrency ATM other than being a gimmick?
You are not wrong about this, some people will prefer to make use of exchanges, while some people will even like p2p exchanges, while some will go a bit further for privacy reasons to make use of noncustododial exchanges like bsiq. But the rise of crypto ATMs are increasing, this is because people see it useful, I noticed these ATMs are very close to or within big stores, malls, super markets and the likes. In this case, many people see it useful to buy from the stores while using crypto ATM for payment are accepted, many buyers will not hesitate to make use of it in this case. The ATM would themselves add a markup, very much like traditional exchanges, these days everyone offering a service usually requires KYC, and therefore that eliminates the privacy aspect that these provided once upon a time, and by using a ATM you are publicly advertising that you are into Bitcoin, and with the recent surges in Bitcoin, one might become a higher priority target than traditional ATM users.
You are also right about this, crypto ATMs terms of services differ, but I too noticed they are moving towards ways individual identities can be easily known, but I have come to think the company providing such services have a mobile number, email or other ways to get in touch to know about their terms of service, some people will first do that to know if to use it or not. Some will not require for anything related to kyc (but I doubt that these days), some will not require for anything other than phone number while buying and selling less than $2000 but it depends on terms of service. Although, giving out phone number can likely compromise privacy, and I have never heard of recent ATMs that will not demand for phone number at certain point either for buying and selling, but these TOS are important because very possible there are some crypto ATM that might still provide the privacy. There's also the fact that these ATMs are usually situated in cities, and therefore require traveling to get to for a lot of people which either adds to the costs, or simply as it was in your case; adds some muscle. I would be particularly interested in seeing the statistics of how often these devices are used, since I simply can't see them being viable for most users, or at least not very convenient.
There are alternatives like you have once mentioned, if someone is not located where crypto ATM is, he/she can still make use of other methods while p2p is available everywhere and easily accessible online, this will be the forgo of those not having crypto ATM nearby, but some users do make sure of it while shopping in stores. People making use of crypto ATM are people that have close access to it while other alternatives are there like you mentioned and I think p2p is just my best way. But crypto ATM is one of the ways more people are knowing bitcoin and the number is increasing because people in the nearest location to it are using it, I think more probably for shopper in stores. |

What can be done? From the quote it is clear that the aid provided will also gets wasted on gambling. We can't blame the gambling sites, because to keep the users within their own control different features like setting our own limits, vault and so many things are available. Even after this people losing in gambling is the true difficulty. Something need to be done at the earliest, or else we can see more people like me suffering out of financial depression. I wasn't able to think anything, my mind always thinks of making myself free from debt.
I was a gambling addict before, the last time I calculated how much I have lost to gambling, it was around $6000, and I am certain it is even more, I had to borrow from people, and my life was miserable, there were even more that happened that I almost killed myself, I know how it feels to be an addict, people around me stop trusting me because gambling made me betrayed their trust, leading to depression for me. Not all can be solved but advising gamblers will just be the best. I remembered at the time, if I have $5, instead to use it for better things I needed at the time, I will prefer to gamble with it, my phone makes it easy for me and make me easily accessing gambling sites. That is why I know if you give gamblers any money, they will also use almost all if not all to gamble, because I have experienced gambling addiction before. I did not take my life, but everything seemed like life should end for me at the time, but today made me realize that if there is life, hope remains, I read about gambling addiction online, I knew I have to stop, and I stopped. I stopped in September 2019, I noticed immediately after a year, after gathering some money on this site, gambling still came back, I started to gamble again September 2020, just a year after I stopped it, but I lost almost $1000, I have to advice myself about this, and finally I stopped. I am pretty sure I have the control now, and even if I want to gamble next time, I will use the money I can afford to lose for it. What can be best done is to advice people, they will be thinking they are professional and can do what others have not done before, until they know the more they gamble the more they lose. Having articles online about it, for gamblers not to go beyond using small amount of money will always be the best way. But many people are not accessing this articles and thinking they will win while using huge amount of money, experienced people like us need to let them know that their are more chances to lose than win. We should let them to always know gambling should be for fun not a way to make money, aside this, I do not think there are other ways. |

It might sounds strange to encourage gambling through this Charity, but my thinking is to give life and hope to overcome the financial stress which is the major reason behind the depression of gamblers. If someone is found losing $5k on gambling and is in frustration. We can support him financially providing $200. Please putforth your opinions and the right way to help Gamblers financially.
This would have been good, but we need to check the other side of it. Assuming I am gambler, I am addicted, I lost all, I borrowed, and I received a support fund. What do you think I will do with the fund? Most likely I will not yet pay my debt but use all or almost all the funds to gamble. Gambling can be so addicting at times, people need to check themselves, what will be best in this case is to just find ways to advice people to not use money they can not afford to lose to gamble, gambling should be for fun. I am so certain the support funds will be used for gambling, only advice is better for addicts so to correct them to gamble appropriately. |

Normally, the withdrawal time for most betting sites can be a day, while some will be processed within a short period of time within a day, I have not seen anyone beyond a day but maybe possible, if the transaction is getting more than two days due to some reasons o_e_l_e_o pointed out, it will be good to read the withdrawal part of the poker's site terms of service, if not beyond the time you have waited, better contact the poker's support center, but hopefully the withdrawal would have been processed and confirmed before then. |

That number was not just taken, it was taken in accordance to some other certain reasons that will make bitcoin deflationary.
If Satoshi likes, he can make the number 21 billion instead of 21 million, in which mining rewards before the first halvings will be 50000BTC instead of 50, while the mining block before next halvings will be 210,000,000 instead of 210,000.
If Satoshi likes, he can make the number 2.1 million instead of 21 million, in which mining rewards before the first halvings will be 5BTC instead of 50, while the mining block before next halvings will be 210,00 instead of 210,000.
This depends on Satoshi Nakamoto, but it has to be done in a way bitcoin will remain deflationary in design, and he chose 21 million after other certain reasons have been considered.
Block hieght before next halving, mining reward and the time set to solve proof-of-work algorithm by miners are all very important before he choose bitcoin total supply.

Now back to the missing BTC... it appears that your address is empty and there is no incoming transaction (not even unconfirmed), so they haven't sent you anything. Which poker website did you use? Did they give you a transaction id?
The gambling sites I have known before works in a way you will withdrawal but not processed immediately, and there could be more delay if they have no enough funds needed to process the transactions needed, that is why it is not appearing on electrum at all because nothing sent yet by the poker site, which means no txid yet until it appears on electrum as unconfirmed transaction, and later be confirmed. |

Just check you sent the bitcoin to your electrum address, make sure it is correct by checking your electrum address again and compare it to the withdrawal address you inputed on the poker site, making sure the withdrawal address on the poker site is the same as your electrum wallet address. If correct, that means the betting site has not processed your bitcoin transaction, it happens like that at times, you will need to contact the poker site customer support and complain to them about it.

is it a good plan?
What kind of trading do you want to learn? Is it stock, forex or crypto? To get it easily, you will need to first read about the 'rules of trading', this is what you can use search engine for, it is very important to know the rules for not to fomo and to be able to know how to manage your risk. If stock or forex trading, you can start with demo account, you can start with watching trading videos if crypto, there are a lot of videos available even for the three types of trading. Check the price history of all the cryptocurrencies you feel like trading, start with $10 per each trades for like 3 to 6 months, do not be greedy and be absolutely patient. You will learn, have experience and be able to know more about how to manage risks. |

I don't know if this is just with me as the Blockchain app I use doesn't recognize Segwit addresses (It has never recognized it once since the Segwit thing came to be). It records them as invalid addresses. Does anyone have similar issue?
I have never used blockchain wallet before, but I just downloaded it not quite long for testing, it does not support both native and nested segwit addresses, it is one of the wallets misleading people to pay high unnecessary fee. Although, it is one of the wallet not recommendable for use, also a web wallet which are most vulnerable to online attacks. For it not supporting segwit is also one of the good reasons this wallet should not be used. |
