My way to senior member
Few months ago, I joined this forum, I was so content with it and happy to be among people here, I did not know what to do, but I wish to rank up. Although, after some times as days gone by, I was able to know few certain things about the forum, I do read what people post, checking the way merited posts are. I tried my best as a newbie and surprisingly received my first merit. It really encouraged me to post more topics and also posting replies. I was able to rank up, it was a great and pleasurable for me. Many ranked members corrected me, I was able to learn from them and know more about bitcoin and other cryptocurrencies in the process, thank you all. And, I am still all ears to correction(s) while also developing myself daily to make the best post.

Appreciation
This will be the first time I am appreciating members on this forum, I did not consider myself as a member before until my first goal was achieved, to be senior member has been my first goal on this forum, that has been what really helped me and get me this far, but that does not still mean everybody that register are not members, but just the way I thought to fulfill my ambition. And I am using this period to thank you people to get me to this rank, many of you always see my post worthy and quality. Without you people, I wouldn't have made it far, thank you.

What I have learnt.
First of all, I will like newbies to go through these two links:
What I have learnt so far, my advices for newbies
My experiences so far and my advises for the newbies

This forum is a great place to be, it helped me such much after I joined, especially while communicating with people, I am able to communicate with people more professionally, even in my home and everywhere I go more than before I joined this forum.
It let me know how people should really be independent of themselves in avoiding scam and how to avoid malicious actors. This is more than someone giving me money. A lot of people are depressed all because they were scammed, some people were financially shaken, some may not recover from scam, some victims can even die. So, this forum is  worth more than someone to give me money.
In short, there are many other things I have learnt, I just mentioned few, this forum helps me to know more about life generally, directly and indirectly.

Encouragement
I started on this forum as a brand new one March 07, 2020, within these periods, I was able to rank to senior member. There are some people that have the mindset that people do sell merit, that people only give merits to friends and people they know, if thinking about that it will be very difficult to rank up, thinking like this will not get you anywhere, it can only make you not to do the right things. Obeying the rules of the forum, researching and contributing what you think can interest people, posting in the ways posts that are merited are will get you far and high. Be hard working, patient and believing in yourself.


Conclusion
I have been on Bitcointalk forum for awhile now, it has really helped me in many areas of life that money may not give, making me conscious how to avoid scammers and helping my communication skills. But, also will mentioned the fact that I have been participating in campaign since I was a full member and earning bitcoin in return.

Topics I created so far
I have created as many as possible topics, but these are few I believe have really contributed to quality posts on this forum in which newbies and many other members could have gained from.

1. Crypto scams revealed
2. Privacy, ways to protection
3. How to secure crypto wallets
4. Crypto scam exchanges and fake p2p transactions
5. Bitcoin wallet summary at glace
6. Suggestions about the best ways to backup seed phrase
7. Hardware wallets, types, security and safety
8. African bitcoin ATMs
9. Recent Corona Virus Scams
10. KryptoCibule, a Windows malware triple threat for cryptocurrency users
11. Malware that can steal bitcoin from wallet devices and their preventions
12. Reasons I prefer non-custodian wallets
13. The bitcoin halving, whales manipulations and its 2020 price valuation
14. Lightning network vulnerability discovered, upgrade immediately
15. Be careful of shitcoins on trading platforms

This is just win to win, members of this forum are wearing the signature and avatar to advertise these companies. There are many users on this forum, we can even form a big community on its own, many members are able to know about the company that are having campaign here through the avatar and signature we wear, from there, we can make use of the service the companies are rendering, for example like the betting companies. If not for this campaigns, I will not know Roobet or Bitamp etc and many other companies having the campaigns here, and other users will not know them too, and will not use their services.

That aside, there are many anonymous users that do visit this site, they are even more than we users, I mean monthly visit of anonymous users are far more than we members of the forum, and these users can know about this forum and interested in the service the company offering the campaign are offering. If not for the campaign, both we users and anonymous users will not know about this companies and we will not use them.

So, with your quality posts, you display these company through the campaign, you let people from all over the world that visit this site to know about this companies through the signature and avatar that appear on each of your post, the companies will pay you because you are letting people to know them. So, it is a win to win just like marketing, you are marketing the companies .and the companies are paying you for that.

But only what I have noticed is that since binance ceo purphaed coinmarketcap, certain things have been changed, there are many coins like that now thay are listed in the rank they ought not to be listed, I have checked two other sites and coingecko now, the listing is good and normal like before unlike coinmarketcap. If there is any doubt in a coin, why listing it where it ought not to be listed, on other sites the coin marketcap like Hex in question are not even listed and makes it not fall in such position binance ranked the coin.

That is why binance is wrong in the listing, if you check binance now, the coin is listed between 17(tron) and 18(stellar) at the up part, unlike other coin listing sites like coingecko that did not even include marketcap for such coin.

I appreciate your answers. (2,3)-threshold multisignature protocol is even off-chain in its entirety, and with what I have read on news lately, I am very sure that BIP340 (Schnorr signature), BIP341 (Taproot) and BIP342 (Tapscript) is now well ready, but only remian to be included in bitcoin core, if this is included in bitcoin core, multisig transactions will be indistinguishable, and I hope the payment for multisig transactions will be lower and be like normal single key payment. So, I think this will be the best choice which is even included in blockchain rather than off-chain.

I have just find some interesting news about EndSARS today, you may like to read. I hope some people that are politicians and that know nothing about how SARS are brutal and endangerng the life of youths in Nigeria will have nothing good to contribute about this. Police brutality must be stopped in Nigeria.

Thanks to pooya87 and ETFbitcoin. But, I do not know why exchanges are still make use of the 3-prefix litecoin addresses, litecoin users do make such mistakes by sending litecoin to bitcoin address or sending bitcoin to litecoin address, that is why developers have come to the invention of litecoin P2SH converted that can convert the litecoin 3-prefix address to M-prefix address. The M-prefix address can be easily differentiated from bitcoin 3-prefix address, and also that the M-prefix litecoin address is not valid on bitcoin blockchain. Although, user can either send to the M-prefix or the corresponding 3-prefix and will reflect on the wallet or exchange.

---

Avoiding User Error
In order to resolve this confusion, the Litecoin community developed a new address format that is prefixed with M, a format that would not be valid on Bitcoin. The underlying private and public key pair are the same, but the hashing algorithm for displaying the public key is altered. This means that 3- and M- addresses are both interchangeable for the purposes of movement of funds on the Litecoin blockchain. This simple change drastically reduces cases of erroneous cross-chain transfers.

To help Litecoin Futures traders avoid loss of funds, we use P2SH-P2WPK deposit addresses with the M prefix. We believe this strikes the right balance of supporting Segwit on the Litecoin network as the community wants, while minimising issues of wallet compatibility that Bech32 address format has.

Wallet/Exchange Compatibility
However, some users may still be using wallet software or exchanges which do NOT support sending LTC to M-prefixed addresses. As a result, you may need to convert the M-prefix deposit address on Crypto Facilities to a corresponding 3-prefix address in order to transfer funds. To easily convert between the standard 3-prefix P2SH address format to M-prefix, you can use this open source tool provided by the Litecoin Foundation: https://litecoin-project.github.io/p2sh-convert/  The source code can be viewed here: https://github.com/litecoin-project/p2sh-convert

Example
Lets say your deposit address on Crypto Facilities is: MV5rN5EcX1imDS2gEh5jPJXeiW5QN8YrK3. Now you go on your favourite exchange and request a withdrawal to this address. But you get a validation error saying this is not a real Litecoin address. As a result, your withdrawal is rejected. To resolve this, all you have to do is convert this M-prefix address to its 3-prefix address. When you convert it, it displays: 3Nsi4BpeZtsLQvkn8p6PZfHFPoUxKbJ1YY

These two addresses are interchangeable. If you send 1 LTC to the 3-address, it will be the same as if you send to the M-address, the underlying keys are the same. The only difference is that some wallets support only 3- and not M-. If you find yourself in this situation, encourage your wallet provider or exchange to upgrade their Litecoin Core node to the latest version and use the converter tool to accomodate the transfer in the meantime.

I have been reading this paper and understanding it little by little. Now, I have known about Threshold Multiparty Computation (MPC) Signatures, and to be specific, (2,3)-threshold multisignature protocol which the paper really focused on. A user which is the client can depend on Service Provider and on Recovery Server in a way private keys can be well protected in a way the two (service provider and recovery provider) can be able to provide the user with the private key at a point in time, maybe due to private key loss.

For example, if the user lost his private keys, the private keys can be recovered in a secure and safe way from the service provider, but if the service provider is affected and can not provide the private keys, the user can recover back the private key from the recovery server also in a safe and secure way.

But, I have a question. Assuming the service provider and recovery server are both affected, hope the private key is not lost forever? Or, no matter what, the recovery server can not be affected and will always be able to provide the private key even if the service provider is affected?

Thanks for the correction, I gained a lot from your post above. I am a bit bad to anything related transactions, all because I looked for book to read about it in details and I have not found a perfect one.

I will make use of the tool, I believed I can learn from the write up found under the tool too. Thanks.

I don't remember where I've read it but someone recommended that we create new wallet address for every transaction to be made.

Coinomi support segwit, I do not know about trust wallet. Exchanges that users can generate new address, if using nested segwit like HitBtc, it will continuing generating nested segwit, and if it is generating legacy address, it will continue generating legacy address. I do not think that is an issue if you can still use segwit to pay into the exchange, exchange fee rate is very high because most of the fee is not for miners but the exchanges themselves.

From the OP link: https://decrypt.co/45537/user-loses-1-1-million-in-aave-due-to-mistake
I hope this is clear, so far the transaction was a mistake and sent to AAVE smart contract address, AAVE can send back the fund and should send back the fund to the owner.

We need to be careful of DeFi projects, studying it very well before making any move. A lot of people have gained from it but many more people have lost from it too, even some DeFi are scam. Learning about it very well is recommended before starting at all.

joniboini is very right, CoinJoin is good but I will advice to make use of mixers which is the best way. Also, you can send the bitcoin to an exchange, exchanges makes use of CoinJoin too, and the transaction is higgly likely not to be traced to you, but I will not advise you to use exchanges due to some reasons but just for you to have little knowledge about it. The best way that your bitcoin can be sent anonymously is to use a mixer, I recommend you Chipmixer.

If you use CoinJoin like on Wasabi wallet, the person will not be able to know. But about custodial exchanges, I only just want you to know, remember custodial exchnages do not provide users with private keys, not your key not your coin, and they often freeze accounts if they are suspecting users, so custodial exchanges are not recommended, and during suspicious activities, the exchange can be able to track your transaction to the person. The best I can recommend is to use a mixer which is totally perfect. If you want to try Wasabi Wallet coinJoin, it is also very good  and I can recommend it to be the second. But, if you can use a mixer, it is the best way to go about this.

I want to add just a comment. Some people may be mistaking that Taproot will be able to make CoinJoin transactions harder to see, although, Taproots hide scripts and making multisig indistinguishable but it does not directly do anything for CoinJoin.” So, what I know for now about taproot is that it will make multisig transactions to look like single key transactions.

And I will like people to know that Bitcoin’s Taproot is ready now, only remaining it to be included in bitcoin core, but it's unlikely to be included in the next release. The Bitcoin Improvement Proposals 340 through 342 were merged into the Bitcoin codebase on Thursday, signaling that the anticipated Taproot upgrade is ready.

The Bitcoin Improvement Proposals 340 through 342 were merged into the Bitcoin codebase on Thursday, signaling that the anticipated Taproot upgrade is ready.

Schnorr signatures (BIP340)
Taproot (BIP341)
Tapscript (BIP342)

What is Taproot?
Taproot is the name given to a proposal coined by former Blockstream CTO Gregory Maxwell in January 2018. The actual implementation was later developed by a team of Bitcoin contributors led by Pieter Wuille. Taproot is a proposal that enhances Bitcoin’s scripts, a set of instructions attached to each transaction that explains how the funds can be used. In its simplest form, a Bitcoin transaction is secured by the recipient’s public key, which guarantees that only he can spend them. Scripts can support more complicated features, like timelocks and multi-signature requirements. The former can restrict money to only be spent after a certain point in time. The latter makes it possible to create wallets with multiple owners. The conditions can be added together, so that there would be multiple options on how to spend the money. For example, the script might say that the funds can be moved immediately if three people agree, or after five days if only two of them do. In Bitcoin’s current implementation, the full scope of the smart contract needs to be revealed when its beneficiary wants to use the money. That means that if only one of the conditions was triggered, everyone would know that there were others.

Taproot removes the need to publish the entire script, and only shows the condition that was triggered. In addition, multi-signature contracts where all parties agreed on a transaction can avoid revealing the fact that there was a script at all. To an external observer it would look like an individual wallet-to-wallet transaction, assuming the parties involved are in full cooperation.

This is made possible by a different feature called Schnorr signatures, which is encoded in BIP 340. Schnorr is considered a more secure and efficient version of elliptic curve cryptography, which is what underpins the system driving private and public keys.

Limited benefits to privacy
Taproot is often mistakenly believed to make CoinJoin transactions harder to see, or even make them indistinguishable from normal payments. In a conversation with Cointelegraph, Pieter Wuille revealed that this is not the case:

“Indeed, it [Taproot] hides scripts and makes multisig (often) indistinguishable. It does not directly do anything for CoinJoin.”

Wuille then added that Taproot is “certainly no silver bullet” for privacy the confusion may have arisen due to an initially planned feature called cross-input aggregation. It was later removed from the Taproot proposal due to potential issues from its implementation. Furthermore, Wuille clarified that it would not directly improve privacy:
“Cross-input aggregation won’t hide CJ or anything else. It’s not a privacy improvement, only an efficiency one (which may indirectly encourage CJ by making it cheaper, but even then, it won’t reduce the ability to recognize such transactions as CJ).”
Thus, Taproot only improves privacy in limited aspects and under specific conditions. For a person using Bitcoin to buy drugs from a darknet market, there is no benefit.

Taproot and the associated technology of Schnorr signatures are considered to be the most important upgrade for Bitcoin in the past year. It is primarily a privacy improvement for complex spending conditions on Bitcoin like multisig transactions, time locks and other conditions based on Bitcoin Script. Taproot hides every additional spending condition beyond the one that was activated. For example, a transaction might be executed immediately if all four multisig signers agree, or it could require a certain amount of time to pass before funds are unlocke if only three out of four signers are present. Normally, an outsider is able to identify every possible condition, but with Taproot they will see only the one that was eve triggered.

Furthermore, thanks to Schnorr signatures, a pure multisig transaction can be made indistinguishable from normal transfers. It is worth addressing that Taproot makes no changes to mixing protocols like CoinJoin, which will remain easily distinguishable.While the initial code for Taproot was submitted for review in January, some complications primarily related to Schnorr signatures required an extensive amount of refinement.

The proposals have now been fully reviewed by Bitcoin core developers and are ready to be included in a client release. Pieter Wuille, the lead developer for Taproot, said “it’s all done, except activation.”

But, you can try to contact blockchain wallet customer care about it. But, how about downloading the blockchain app and try to login through app. But, I will recommend you not to use blockchain wallet because it is a web wallet, it requires emails which supposed not to be. If you remember your seed phrase, you can try and import the seed phrase on another wallet other than blockchain. You can try electrum wallet if it is only bitcoin that you have on the wallet, but if you have other coins, you can try trust wallet. By importing the seed phrase on trust wallet, you should be able to recover your funds.

Yes, I understood now, and thanks for the more clarification, the statement only means that more addresses can be generated and still be used for transaction and be signed by M.

What I do not understand is that, assuming if one of user with n lost his private keys, but still needed to be included and needed his own private keys, and it is agreed upon by other users. What will happen? Will the users have to create another multisig wallet, and M users send all the bitcoin in their previous multisig wallet to the new multisig wallet? So that things can be like before.

Please, never mind my question, I am still somehow new. It is about the statement that 'funds can be moved to a new address' if one of the n≤N−M users of the multisig wallet lost his private keys, I am confused and I will appreciate clear explanation, I was thinking if one of the users n≤N−M lost his private keys to control the bitcoin on multisig wallet, that means M users that still have control over the bitcoin will move the bitcoin to a new wallet entirely, which means a new private keys will be generated entirely. Is this what the statement is implying?

pooya87 is very right, legacy and nested segwit calculate transaction fee in size which is in satoshi/byte, but native segwit calculates fee in weight which is in satoshi/vbytes. The weight of the transaction makes the fee in native segwit to be reduced than in nested segwit and legacy.

Secondly, if you are sending from native segwit address to non-native segwit address, the transaction fee will still be high, the only time the fee will be low is when you are sending from native segwit address to native segwit addresses.

I will advice you to also list the wallets that are supoorting native segwit addresses to be included, because the wallet people will be looking for are the ones that support native segwit, and going through your topic can make them easily identify wallets that support native segwit.

I want to comment about this, it was a mistake I think, the 12 to 24 words are not mnemonic passphrase, they are actually called mnemonic seed phrase, which are simple words to be used to generate the keys of a wallet, passphrase is different and it is just like a password used to protect the seed phrase which is introduced through a process called salting in which the passphrase will lead to generation of different seed entirely.

If you see it from the real perspective, you will be able to know that fiats are subjected to governmental manipulations, governments are the ones controlling the real value of fiats, not individuals. For example, the richest man in Africa is from Nigeria, there was a time this man, Aliko Dangote was worth $22 billion, but now at $10 billion, see what fiat has done to this man value in the world, he was the 23rd richest in the world as at 2016 but now at around 160 richest in the world. What caused it? Is it not governmental manipulations. That aside, dollar itself still depreciated while comparing to bitcoin specifically. Then what good side does fiat have than to use it to buy and sell because it is the legal tender.

I have to reiterate this, what benefit can fiat give me than buying and selling? Nothing. I have my savings in bitcoin and some part in altcoins, fiats like dollar are still even better, while some/most fiats are absolutely useless. 

I can never diversify my funds on fiats, the only usefulness of fiats for me is spending, I only convert bitcoin to fiats anytime I want to spend, and if the spending can be made in bitcoin, I will prefer to use bitcoin, if the fee is too high and support altcoin with low transactions fee, I will choose altcoin. Diversify funds in this perspective means to save some of funds in fiats and bitcoin, this is not possible on my side as fiats are depreciating assets. As strong as US dollars is, it is still subjected to inflation, all fiats are subjected to inflation while those from developing and underdeveloped countries are subjected to hyperinflation, but the degree only varies according to the economic condition of each country of the world.

Fiats as nothing to be compared with bitcoin in terms of value and appreciation, fiats are depreciative asset while bitcoin is an appreciative asset. I hope this point is clear and remains the fact.

This news portrayed what fiat currencies are truly are, it tells the big lies of fiat currencies, how the bitcoin genesis block being the beginning of new testament against fiats controlled by govermentd (central body) has subjected humans into which makes humans not to know the real fact about money which supposed to be 100% controlled by the owners, not in a way centralized body will control some aspects that is rendering fiats ro have little to no intrinsic value due to inflation and hyperinflation.

No need to suffer from centralized systems since the world has been offered its greatest weapon against it: bitcoin and other cryptocurrency. https://cointelegraph.com/news/bitcoin-genesis-block-is-the-new-testament-of-finance

This, in a metaphorical way, is exactly what fiat currency is — a bluff, a farce. So much so, thatRichard Russel fiat currencies as:
“The greatest fraud ever perpetuated on the American public.”

The deceivers here, of course, are the governments and central banks. To define, fiat currencies are government-sanctioned money, whose value is merely on a contract of trust between the issuing government and the citizens: It’s not backed by any physical commodity of value, say, gold. That is as good as saying that fiat money derives its value out of thin air.

Bitcoin gives power back to the people
Governments can make a fool out of us only because we trust them. On the other hand, before Bitcoin and cryptocurrencies, there seemed to be no other way. Now, the times have changed, the death bells for government-sponsored scams have been tolled, and their echo resounds louder every moment. In introducing its underlying blockchain technology, the Bitcoin genesis block ushered a new reality. While storing and transacting value, we can now put our trust upon infallible mathematical algorithms and not corruptible intermediaries. Bitcoin introduced the possibility of a trustless world, eliminating the need for banks or any other middlemen. Now, two people can directly transact value (money or otherwise) over networks that are inherently secure and transparent. Above all, the value of Bitcoin (as well as other cryptocurrencies) is based on the pure demand of its users. As such, the dubious motives of centralized governments are powerless. We still have a long way to go in a world where Satoshi Nakamoto is the original creator and the Bitcoin genesis block is the first chapter of its bible. Maybe we could even create a new calendar with 2008 as the first year.

There are more explanations there why fiat currencies are not perfect enough, why bitcoin and other cryptocurrencies are good alternatives.

If you can check this link: https://cointelegraph.com/news/fiat-inflation-has-cost-bitcoin-hodlers-20-over-the-past-decade/amp. You will notice how fiats has contributed to bitcoin price increase since 10 years ago. Fiats devaluation which we call inflation is responsible for 20% increase in bitcoin price. Bitcoin is typically denominated in USD which is not immune to depreciation.


Bitcoin price versus Bitcoin price adjusted for inflation. Source: Cointelegraph.

https://cointelegraph.com/news/fiat-inflation-has-cost-bitcoin-hodlers-20-over-the-past-decade/amp
In the decade that followed the economic crisis, the U.S. enjoyed some of the lowest inflation in history, which hovered around 2% annually. However, over the decade, this added up to almost 20%. Thus, if we use the 2010 dollar as our base and apply its subsequent depreciation to the price of Bitcoin, then the current price of $10,466 turns into $8,770. Though this may be a sobering realization for some long-time hodlers, it does not mean that Bitcoin was a bad investment or that it is not a good store of value.

My conclusion about your question
So far fiat inflation lead to 20% in bitcoin price in last decade when the price of bitcoin is so volatile from a price of $0.03 to $11000 this time, that means it is very possible that fiat inflation, specifically dollar inflation/devaluation will result into bitcoin price increase of more than 100% possibly in the next decade.
