Yubiko is an interesting 2FA hardware.
It is not designed to store cryptocurrency.
You should use Trezor or Ledger as hardware wallets (most reliable companies).
Both of them have support to FIDO2 technology (they do what Yubikey does), so you shouldn`t buy Yubiko IMO.

Sad...
It is always good to make a small research in social networks (like this forum or Reddit) before using a service like this for the first time.
Even when looking for an exchange or a new wallet it is always good to look for users opinions.

I was able to do it. I dont know exactly what happened.
I made a transaction from another wallet, my ledger, using MEW.
Later on I tried coinomi again and it worked. I have no clue what happened. lol
Maybe was a problem with coinomi servers? Or maybe when I sent the first balance to the address in binance, it may have trigged something in the receiving address? I dont know much about ethereum erc20 tokens.

Ok so is obvious that if I restore the wallet through seed the btc inside are restored too. I didn't think it was automatic, that's why I asked.  And yes, I see the file has no exstension! The seed is basically a list of all the possible private keys in your wallet. So, you are just importing all privatekeys in your new wallet software. I don't think "automatic" is the best definition, you are restoring your same wallet (even if it is a different software). |

I always liked Coinomi wallet, as it is a multicurrency wallet that I never had any trouble. However I am facing an weird problem today. I have some old TRX ERC-20 tokens, which I never traded for TRX blockchain. Binance and Kucoin still offer the swap for free, so I was going to do it today. I successfully added TRX erc 20 ( https://etherscan.io/token/0xf230b790e05390fc8295f4d3f60332c93bed42e2) to my coinomi wallet. (the correct decimals, 6, and the contract address). However, Coinomi doesn't recognize any past transactions of this Token, even though it recognizes the correct balance. When I try to send the transaction it just says "Transaction Broadcast error". My app is updated. Any thoughts on this? I can still transfer any ethereum. Maybe coinomi is blocking transactions from this token deliberately? I asked a question about it on their official Reddit, no answers so far... |

It is also prevalent on crypto exchanges as the remnants of transactions that remain in wallets and can no longer be user or transferred.
This statement makes no sense to me. Maybe am I missing something? The guy who sent the dust is watching. But the remaining balance he could be watching anyway, even if he didn't send any dust to the address. If you don't use the remaining balance with other addresses in the same transaction you are just fine imo. Any thoughts? |

This signature has no signed message associated, so it is worthless. This guy doesn't have 26 BTC.
So he begins his story with a lie.
Do your own research

Additionally to what other said above
The main reason is trust.
When a new full node comes in, it just needs the Genesis block and then it starts checking all past transactions without trusting anyone but the Genesis block.
If someone decided"after block xxxxx we don't need to verify back transactions anymore" we would need to trust that there is no single malicious transaction in that registry.

Maybe? OH ITS COMING ALRIGHT. Its definitely coming. The entire planet is facing through a shitshow. Cannot even elaborate on how bad things are. Hong-kong protests, India-Pakistan fight for a state called Kashmir, US mass shootings(249 this year alone) This maybe unrelated, but I had to share. Governments are trying to profit from mass shootings!  Like I don't even understand how people think they are gonna get through all of this, when they get offended when someone says fuck you in the face.
If things don't get taken care of as soon as possible, we are going to see a repeat of what happened in the early 2000s, but this time only a zillion fucking times worse.
The markets are gonna crash, be it stock, crypto, real estate or any fucking investment based market. People are already fucking killing each other for slices of bread in the Africa and some parts of Europe-Asia. There is debt everywhere. Now we have Bitcoin. We can protect ourselves from this. I believe this debt everywhere is the main problem. There is a global financial pyramid scheme, which always explode from time to time. But bitcoin is different. My idea is to save some money now, so I can buy all cheap soon, when it all crashes. And do not sell many of my bitcoins, even if the whole stock market is with a huge discount. |

Few months ago I discovered the Cypherpunk Manifesto. I didn't discover it in bitcointalk forum, but in articles that I read about crypto and technology (I love to read these kinds of articles, I read many per day). I think more people here should be talking about the Cypherpunk Manifesto, as it is strictly related to bitcoin and to privacy. No doubt it influenced bitcoin creation a lot. Cypherpunk Manifesto was written in 1993 by Eric Hughes. It is amazing to see something that was written almost 30 years ago to be so relevant today.
A Cypherpunk's Manifesto
by Eric Hughes
Privacy is necessary for an open society in the electronic age. Privacy is not secrecy. A private matter is something one doesn't want the whole world to know, but a secret matter is something one doesn't want anybody to know. Privacy is the power to selectively reveal oneself to the world.
If two parties have some sort of dealings, then each has a memory of their interaction. Each party can speak about their own memory of this; how could anyone prevent it? One could pass laws against it, but the freedom of speech, even more than privacy, is fundamental to an open society; we seek not to restrict any speech at all. If many parties speak together in the same forum, each can speak to all the others and aggregate together knowledge about individuals and other parties. The power of electronic communications has enabled such group speech, and it will not go away merely because we might want it to.
Since we desire privacy, we must ensure that each party to a transaction have knowledge only of that which is directly necessary for that transaction. Since any information can be spoken of, we must ensure that we reveal as little as possible. In most cases personal identity is not salient. When I purchase a magazine at a store and hand cash to the clerk, there is no need to know who I am. When I ask my electronic mail provider to send and receive messages, my provider need not know to whom I am speaking or what I am saying or what others are saying to me; my provider only need know how to get the message there and how much I owe them in fees. When my identity is revealed by the underlying mechanism of the transaction, I have no privacy. I cannot here selectively reveal myself; I must always reveal myself.
Therefore, privacy in an open society requires anonymous transaction systems. Until now, cash has been the primary such system. An anonymous transaction system is not a secret transaction system. An anonymous system empowers individuals to reveal their identity when desired and only when desired; this is the essence of privacy.
Privacy in an open society also requires cryptography. If I say something, I want it heard only by those for whom I intend it. If the content of my speech is available to the world, I have no privacy. To encrypt is to indicate the desire for privacy, and to encrypt with weak cryptography is to indicate not too much desire for privacy. Furthermore, to reveal one's identity with assurance when the default is anonymity requires the cryptographic signature.
We cannot expect governments, corporations, or other large, faceless organizations to grant us privacy out of their beneficence. It is to their advantage to speak of us, and we should expect that they will speak. To try to prevent their speech is to fight against the realities of information. Information does not just want to be free, it longs to be free. Information expands to fill the available storage space. Information is Rumor's younger, stronger cousin; Information is fleeter of foot, has more eyes, knows more, and understands less than Rumor.
We must defend our own privacy if we expect to have any. We must come together and create systems which allow anonymous transactions to take place. People have been defending their own privacy for centuries with whispers, darkness, envelopes, closed doors, secret handshakes, and couriers. The technologies of the past did not allow for strong privacy, but electronic technologies do.
We the Cypherpunks are dedicated to building anonymous systems. We are defending our privacy with cryptography, with anonymous mail forwarding systems, with digital signatures, and with electronic money.
Cypherpunks write code. We know that someone has to write software to defend privacy, and since we can't get privacy unless we all do, we're going to write it. We publish our code so that our fellow Cypherpunks may practice and play with it. Our code is free for all to use, worldwide. We don't much care if you don't approve of the software we write. We know that software can't be destroyed and that a widely dispersed system can't be shut down.
Cypherpunks deplore regulations on cryptography, for encryption is fundamentally a private act. The act of encryption, in fact, removes information from the public realm. Even laws against cryptography reach only so far as a nation's border and the arm of its violence. Cryptography will ineluctably spread over the whole globe, and with it the anonymous transactions systems that it makes possible.
For privacy to be widespread it must be part of a social contract. People must come and together deploy these systems for the common good. Privacy only extends so far as the cooperation of one's fellows in society. We the Cypherpunks seek your questions and your concerns and hope we may engage you so that we do not deceive ourselves. We will not, however, be moved out of our course because some may disagree with our goals.
The Cypherpunks are actively engaged in making the networks safer for privacy. Let us proceed together apace.
Onward.

Bitcoin deplore regulations, and is basically immune to them (if we manage to keep it decentralized) |

There is no general answer for this, as any coin can choose how to deal with this kind of misbehavior. I couldn't find a definitive answer for this in Ethereum Casper FAQ. But I found this: https://github.com/ethereum/wiki/wiki/Proof-of-Stake-FAQ#are-there-economic-ways-to-discourage-centralizationOne strategy suggested by Vlad Zamfir is to only partially destroy deposits of validators that get slashed, setting the percentage destroyed to be proportional to the percentage of other validators that have been slashed recently. This ensures that validators lose all of their deposits in the event of an actual attack, but only a small part of their deposits in the event of a one-off mistake. This makes lower-security staking strategies possible, and also specifically incentivizes validators to have their errors be as uncorrelated (or ideally, anti-correlated) with other validators as possible; this involves not being in the largest pool, putting one's node on the largest virtual private server provider and even using secondary software implementations, all of which increase decentralization. This is not exactly the question that you addressed, but they are suggesting here to destroy coins from nodes that misbehave. Everything is still a proposal in ethereum casper (POS). But, one other way to deal with this malicious user is to put his deposit as a block reward so it could be shared like transaction fees to validators. |

This is my stance on things. When creating my reporting thread that wasn't primarily kept on the forum drafts, and I only used it to preview it to find any formatting issues.
Yes, this is an additional point. You cannot format your post properly using an external editor, as tables, quotes, links, etc may work slightly different here than in your editor which cannot generate previews. Since we barely use the drafts then I think we don't have to issue any development about drafts. It is the other way around. People don't use it because it is poorly designed and doesn't fit user's needs. Each time you click "Preview", a new draft is saved. That means you'll quickly reach 100, my oldest draft is often barely a day old (meaning 100 new ones were saved in a day).
As a result, I barely use the draft page indeed, unless I want to find back something that I accidentally didn't post yet.
Yes, this is the case to me. I only use the draft page by accident. If my browser crashed I can recover my post. But that shouldn't be the only use of the drafts page. |

About passwords, certainly the only password you should know is your strong password of your password manager. All other passwords should be automatically generated by it.
Also, use 2FA everytime it is possible.
With that practice, you doin't need to change any password ever, imo.

You can also save your words in a different language, that may confuse thieves too (for example https://github.com/bitcoin/bips/blob/master/bip-0039/spanish.txt). However, if you start to make a very confused encoding in your seed backup, it may be more problematic to you to recover it later. Another problem I see is about inherit. If you hold any significant amount of crypto, it is a good idea to give instructions to a family member so he can recover your funds when you pass away (if you have kids for example). And many bitcoins are lost because many people didn't believe that could be worth much one day. Maybe 0.01 bitcoin may be worth a lot someday. If you have a complicate encoding for your seed, it may be difficult or even impossible for a family member to recover your seed. I think the best option is still to hide that paper back up very well. |

Some people in this forum hate coinomi because it is not open source, and because its mobile version had a bug that could share seed with Google docs (something like that)
However, it is a convenient wallet, in the mobile version. There is no multicurrency wallet which is open source. Also, the Google bug with the seed never affected the mobile version.
These sentences are contradictory. Unless OP mentions that he needs a multicurrency wallet, we should recommend the best option for Bitcoin only since we are in the Bitcoin Technical Support board. Sorry, just correct my mistake. The bug affected the Desktop version, not the mobile one. |

So, imo, you can use the mobile version to hold small amounts of money, especially if you need a multicurrency wallet.
For large amounts, ledger nano and trezor are the best choices, no doubt

When I need to draft stuff I normally use notepad or a built in text editor to keep a copy of what I want to write and just have the going as it is...
If it's important enough to keep after 7 days, it's important enough to use in an external editor.
I can guarantee you that not many people use the drafts feature or even care about it, so this whole feature exploration thing would only happen for a handful of people , if it were to ever happen. What you guys are saying is basically "as nobody uses it, it is fine the way it is, just use an external editor". Wasn't this page supposed to be used? And just automatically saving drafts at random and deleting them after 7 days is pretty useless IMO. I think we have an internal draft page, that could be put to use just by changing a few lines of code. It is useless as it is, because it doesn't allow you proper manage your drafts (delete, save, copy, duplicate, etc) I use an external editor also. But hey, we have one here. We can't we make it useful? Any particular reason why you'd like need to save a post as a draft and not post it for months? Yes, I can think of many uses for that. Don't you use your e-mail drafts page? Few time ago I wrote a draft of an enormous posts, which I put some effort in formatting. I was lazy and decided to finish it later (as I needed to wait for someone's response before publishing. I saved the file in notepad, but my laptop was stolen.... If drafts were different... |
