It will also provide you with 16 "recovery codes" which can be used once each in the event you lose your phone or other 2FA device. Much like your mnemonic seed, you should write these down on paper and store them somewhere safe (not electronically).
One additional and confortable way to back up your 2fa is to use Authy. Authy allows you to save your 2fa codes in your account, so you can multiple devices as a back up. It is not as safe as writing in a piece of paper... But after adding the devices you can disable "add new devices" function, so at least in theory nobody would have access to your account in a new device. I made a small topic about it here https://bitcointalk.org/index.php?topic=3178131.20 |

As you can see, 9 Old Era Newbies have made it to Hero, 40 Newbies (34+6) have reached Sr. Member, 111 Newbies (25+86) to Full Member, 3.357 to Member and 10.433 to Jr. Member.
Those you’re really focusing on now are the 9 Newbies that made it to Hero (nobody has had time (Activity) yet to make it to Legendary from Newbie starting from scratch under the Merit System).
I am one of those 9. Created an account with 0 merits, newbie. I am going to confess that when I discovered this forum the merit system was just implemented, I though "I am fuked, i will never rank up". It was very hard to earn my firsts merits. One by one, really hard. My objective was to become one day a Full member (100 merits). It wasn`t effortless, but I enjoyed the path. I learned a lot here, and after a few months I was more worried about building a reputation here and enjoying the forum than about ranking up... The advice I can give you is: Enjoy the forum, read mastering bitcoin, watch you tube videos about great people in the ecosystem (vitalik buterin, antonopoulos, etc), study whateever you like here. If you enjoy politics, go to politics and society board. If you make constructive posts there, you will be merited. Do you like statistics? Make some statistics about anything forum/bitcoin related and post here. Do you like religion? Go to off topic board. There is space here to rank up the way you like. Make your own path, there are no strict rules about how to rank up. Meta appears to be where the merit rains. I'm not completely sure why.
In my opinion, this is a problem with the merit system. People are incentive to post there because it is easy to get merits there, and it is not a session where there are bitcoin or cryptocurrency related discussions, which is the focus of the forum. |

Last: don't forget Bitcoin Gold, it's still worth a few bucks.
There are other forks which may still be worth claiming, as they have support in decent wallets such as coinomi and some not so shady exchanges... BCD for example can be claimed in changelly, pretty easy and secure. I would definetly move the BTC first. Then I would claim BCH, then i would worry about BSV, then BTG, BCD and so on... go claiming the more valuable forks first, and in the end you will have private keys with a lot of shit forks, which can all be claimed and there is no risk of losing any valuable coin. |

Hello,
I know that Grin has a different way to handle transactions and wallets and addresses whatever.... Is there any easy to use wallet already? I have a few in some exchanges I want to make a wallet.

Technically, he never sent you any bitcoin.
He just gave you his public address, and you were only watching his funds.... They were never yours...
Next time you need to create a personal wallet and you will give him your public address, not the opposite. Then you will track if you received coins or not.

The best thing is to manually write Electrum.org in your browser. The same with bitcointalk.org
Clicking in links or Google Ads for those websites are the most dangerous options.

+1 for Protonmail. Also been hearing a lot of good things about ProtonVPN, although I haven't tried it yet myself.
They have a free Version, it is worth checking out. I had to wait a few months to get access to their VPN for free, I don`t know if it is open to everyone now or not. I use it sometimes, it is safe and I trust them with my data. Certainly a good company which it is worth supporting also. |

Just a small update.
I have closed all channels (2, one created by and the other probably created by loycev). I received a few Satoshis from those channels, but in the end this test was expensive. I don't know exactly why because the fees aren't very transparent.
I send 0.0011 BTC to eclair, and my final balance now is 0.000652
Open and closing channels are transactions... I sent to eclair with 3 sat/byte and create a channel with 13 sat/byte. Even with those relatively low w fees , this was quite expensive.

Would definitely take a look at protonmail. A lot of friends have already recommended it as well so this time I might take it.
I don't know if Apple is any better, as they probably read your emails as well. We are fuked up.. let's do what we can to preserve our privacy.. About proton mail, as least you should create an account there with a cool account name while it's still a small company. I have a few emails there  |

How much do I need to pay?
In my opinion you shouldn't worry much. 13 sat/byte is a reasoneable fee. Few days ago I made a transaction with 3 sat/byte that was confirmed in 17 hours. can you wait for that? Unless you are in hurry, don't worry.It will be confirmed in next 24hours. Your fee is not that low. |

Thanks for mentioning my topic. As I said in some other topic about privacy, Let´s Talk About Privacy, you should always avoid any Google service or software, as they are always collecting your data. This include reading your e-mails. This may not be a problem for personal use, depending on the person. But for cryptocurrencies or any other financial use, I believe it´s better to use some more secure e-mail, such as ProtonMail, as you mentioned. ProtonMail is by far the best out there, IMO. ProtonMail is not a real competitor, as it has a difference niche (more privacy and security focused users, not for general public. Its free version is somewhat limited to be your only email also). |

Did you download from electrum.org?
I suggest that you delete this one and download fr electrum.org, just to be sure.
If you download from there, its safe, no problem no other website is legit.there are many phishing Electrum websites out there.

- So, the transaction size in bytes will increase too right? Then it still okay to use a low satoshi/byte fee even the txn size is big?
This is not a con for that case? The is calculated based in your Satoshi/byte. This is all you can control. The number of inputs will increase the size (bytes of your transaction). You can consolidating your inputs with 1 Satoshi/byte , and it will confirm in a few hours if fees are low. Fees are high now... But I managed to do some consolidation with 3 sat/byte few days ago. But when I did this, does the still the same if I will combine all input into single one address of the same wallet? than sending those input to another wallet address?
As I said , I doesn't matter if you have one address or not. One address may have hundreds of inputs. You can consolidate in the same wallet or another one if you like, it doesn't make any difference |

Distributed Consensus
When Satoshi Nakamoto came up with the PoW consensus, he didn’t mean to further the research on distributed consensus done by the scholars. People intend to consider that his PoW consensus provides a solution for distributed consensus in Byzantine environment, giving it an academic perspective, and we start to connect them together.
Speaking of the distributed consensus, we have to include "FLP impossible" theorem in our discussion. "FLP impossible" theorem is come up with and proven by three scientists, Fischer, Lynch and Patterson, in their paper "Impossibility of Distributed Consensus with One Faulty Process” in 1985. The theorem concludes that there is no deterministic consensus algorithm that can solve the consistency problem in a minimum asynchronous model system that is reliable in the network but allows node failure (even if there is only one). The revelation of this theorem is that the technically workable distributed consensus must be compromised in some respects.
This is a copy paste from https://medium.com/@yeefoundation/is-pow-outdated-what-are-the-essential-advantages-of-pow-consensus-6d12f0851007It really looks like you may tbe the author. But why don't you include the source? Your account may be banned for that. Also, try to add some discussion with the knowledged you have, don't just throw a wall of text here.. |

My questions are:
1.) What are the pros/cons of changing my receiving address for every time I receive a bitcoin to my Hierarchical Deterministic wallet? There are no cons. The xgood side is that it protects your privacy , as you are giving someone a never used address so no other transaction can be traced to you. 2.) I also noticed that if you have much input in one transaction, the transaction size gets bigger, then it requires some huge fee to confirm my transaction.(Let's say my example transaction above is executed).
- How can I prevent or solve this problem (having a huge fee)?
The number of inputs do not depend on the number of addresses, but number of transactions. You can have 30 inputs in the same address The solution for this is to consolidate your inputs when fees are low. To do this you just have to do a transaction to your own wallet. You could do that anytime actually, if you have no hurry. Just set 1/sat per byte and wait . Guide here by LoyceV https://bitcointalk.org/index.php?topic=2848987.0 |

Oh, this is what you mean about full control of funds. You're probably right, Ledger Live have less features than Electrum, and as mjglqw said, not supporting bech32 is probably most annoying thing for me. So, it's good that we have choice and use Ledger with Electrum if needed. Single Electrum without hardware wallet usn't bad choice, but not safest.
Ledger love is a nice software, it's safe and clean interface... But I think it lacks features. I use it for some altcoins, but even in ethereum blockchain it's not enough, as we still need third party solutions for token management. For BTC I use only Electrum for the reasons already mentioned |

I’ve just glimpsed through the whole Reddit thread, and it seems that the person in question:
- Did let others in his circle know he had BTCs.
- The ledger was pin password protected.
- There were two copies of his 24 word seed:
- One hidden somewhere, on paper, with the words in order.
- Another in an email draft, with allegedly 3 words jumbled, but the rest in the same order.
So it is feasible that:
- Someone acceded the 24 word seed hidden at his home (words in the right order), since people were likely aware that he had it somewhere there.
- Someone acceded the 24 word seed in his email draft, and since he only altered the position of a few words, perhaps he just swapped the first for the last (really swapping two words, not three). That would be the first option one would try, aside from reversing all words. If only 2 or 3 words were switched, the number of combinations to try is drastically reduced.
Even using a hardware wallet you must still be worried about your seed safety. This is a serious problem and often neglected in my opinion. It's very important to hide it somewhere and a back up, where nobody could access it but you and a trusted family member (in case you die, in my situation it's important) Inserting the seed in your Gmail is very crazy .... Even changing a few words |

Eur might replace dollar only if in long term UE economy really does well. It will take years for that to happen and I don't think they are in a good direction. Us economy is performing really well, just take a look at their stock market.
