If all the variables are the same, native segwit (bech32) is the cheapest. First variable you didn't change, was the transaction fee. Electrum allows you to manually set that, regardless of network. You can force it to 1 Sat/B, if you don't mind waiting a few days to complete under current conditions.

There is also the number of inputs, if you have your coins spread it its more expensive than if they are all in a single address. Of course that also goes against privacy. Electrum has a couple of options that you can disable to tweak that as well.

Those "2MB from the TIP" is how further you are from getting processed, 2MB is rather low, i did a transaction last week and it was 40MB away, but it got processed anyway after a couple of days. Only if you are in a hurry and don't care spending more to have it quick, should you let either the wallet choose for you or you manually use a higher fee. You can also start with a low fee and then "speed it up" later, as long as you have more funds willing to spare into the transaction fee.

Are you serious? Your seed words can be used to generate your private key, What are you even talking about? Lose them and lose your funds if you don't care.

The seed words are the MOST IMPORTANT THING. And you are NOT going to type your private key by hand in piece of paper, do you? If you copy paste it, or print it, you might as well be giving your money away to others. How clueless to computer security can you ever be? Did you not pay attention when they told you to write your seed words BY HAND? Why do you think people stopped using paper wallets with printed private keys?

Now your "problem" is non existent. Download a recent live linux iso, boot from that, install the various Electrums and use your seed words to get access back to your funds. Your distro is too old to handle a recent Electrum?

Or why don't you use a virtual machine to install something recent? Some people have come here asking how to make run the newer Electrums with their old distros, but here you are blaming it on the seed words. Seriously, its like you'd rather lose your money than focus on your REAL problem.

Oh yea, Electrum does run in pure cli mode as you already found.

BIP39 are the "compatible with legacy" Segwit addresses, those starting with 3. You don't need to bother with that, even Bitcoin Core is now using native segwit by default and you can send to any address anyway no matter what style your wallet is using.

You can't, you were a victim of fraud. The message you saw was a trap sent by phishers and you downloaded and installed a fake wallet to steal your coins.

Never trust the internet, or your computer, especially with money or privacy. Double check first if its true or you are getting lied.

Internet is not a safe playground, it is dangerous, VERY dangerous. Apple is not going to protect you either, do not trust companies.

Your money is lost. Some people have lost millions, because they did not took due precautions, they didn't double/triple check before touching the software, or made sure to use a secure computer with a secure OS to handle large amounts of money.

In Bitcoin, all transactions are final.

This is false. Translate this:

In Bitcoin, all transactions are final.

There is a warning in the official Electrum page since version 3.3.3. This is not an attack to Electrum, but against users. Electrum cannot stop thieves from convincing you to download their fake software, if you do not put the smallest effort to investigate things BEFORE bad things happen. Electrum cannot police the world. This is not Electrum fault.

Of course a collective effort could be made to report such incidents, and exchanges or online services might agree to help freeze the funds if the thieves try to use their service.

You are not the only one, many people fall pray by internet thieves, because they exploit the weak human nature when the software is good.


This is the same as if you are going to the bank with your money to make a deposit, but the street is blocked because someone parked a large truck in the way. While you are waiting, an unknown person approaches you, shows you a Bank card and informs you he represents the bank, that you could trust your money to him. AND you decide to hand over your money, thinking he is honest. Then you never see your money or the individual ever again.

This is what a phisher does.


How are we going to stop people in the world to stop falling to the tricks of phishers? We try and try to warn people, but there are millions who never bother until its too late.

Its already bad with people sending forked altcoins to mainnet (or viceversa), imagine if testnet used the same...

You are correct in your appreciation, and this will in fact occur. But you have to zoom out the time frame. This process has been delayed by both technological advance (smaller asic nodes) and bitcoin price evolution, but in the long run neither will cope and mining is destined to become less and less profitable until most people leave and the hashrate goes low.

Do know that halving also presses the bitcoin price up due to slower production, but it shouldn't cause it to "double", so its not going to remain as profitable to mine as it was. This is by design, large miners who fail to see this might end losing all their money at the end (not unlike cloud mining).

As for the 51% attack, don't even bother. It may feel like a lower hashrate, but its more expensive as well. Those who remain mining still make it very expensive to try such attacks. You will see it because the hashrate is going up while the earnings will go down, even after it becomes less profitable, because of the asic becoming more efficient and cheaper.

Thing is you won't see as if standing today and simply moving one variable (hashrate down), you have to add the other variables, such as asics getting better. We are entering the asic miner is @ 50T era, from the 10T era. By the time the halving comes those 50T miners will earn like today 25T miners, but spending twice the power.

And what is the incentive for a home user to run a full node? I have to spend storage, bandwidth and other costs of keeping a server online, yet i'm not getting a single satoshi for it.

Even worse, i know miners earning plenty don't even bother setting one in an old pc next to their hundred or thousand asic miners...

Yes i figured as much, being the manufacturer also helps... Unfortunately those racks were designed for the older form factor, and this is a quick re-purposing. A proper designed rack would leave no room for horizontal placing, but its bad some customers would see this video and think its ok.

KanoPool support goes something like this: If an user loses a password, he/she has to make a new account (with a different login name), the end.

Kano used to respond very quickly on IRC, not sure about this newfangled Discord thing...

Take a working miner, take all its asic boards out, and then test them all the asic boards from all your miners one by one there, so you can know for sure which ones are working.

After that, with a single known working asic board, test your controllers, also one by one (either move the asic board around or the controller, doesn't matter.

Its important to test them one by one before continuing, so you know what works and what doesn't.

Finally, with a known working controller with its 3 asic working boards, test each psu from all your miners one by one.

At the end you are going to know exactly what (if any) asic boards, controllers, and PSUs got damaged (if any), and take informed decisions.


Of course this is only with faulty miners plus a good one, if you have several good ones there is no need to check those.

A wooden box with sound insulating fabrics inside works better, coupled maybe with sound insulating ducts attached to the box (NOT the miner).

Fan speeds can be adjusted with Braiins OS, but he was complaining about noise at start time, before the firmware has any chance to do anything.

In the end Trump seems to just want juicy deals with them, its empty threats. How is this related to Bitcoin? I fail to see any connection. Bitcoin is not country bound, and its designed to avoid being stopped.

Trump is lately annoying a bunch of Chinese companies, they could simply look elsewhere to do business with. Things in the USA are simply getting more and more expensive.

NO, because they are too late to the game. Its going to flop. They should have adopted an existing coin, preferably the best: Bitcoin.

The amount of diverse "digital payment systems" is getting out of hand, and people aren't going to bother even with Facebook behind.

Facebook is not as strong as they think. I could cite Bitmain, by getting involved with an altcoin, was almost run into bankruptcy. And this is a company WITH crypto experience, unlike Facebook.

Of course it should be mentioned that this is probably getting whatsapp/instagram involved as well, as all three are owned by the same company. But that isn't going to cut it.

They call them "Global" but being Facebook its already tied to US laws, that immediately negates its name. Bitcoin IS global, this never will.

If Teslas talked to each other open mesh style, that would be worth something. Wherever they see merits in using a blockchain as well, its for them to decide. Perhaps if they need security that the reports don't ever get altered or something like that.

If you mean that each car would be a full node to their blockchain, instead of using central servers, i guess that would be cool too.

IIRC Teslas already have dual computers, one takes care of the essential driving, and the other is the infotainment. This second computer could be given that task, or they could add a third one for that specific job, and make sure that if it fails, nothing else gets impaired.

I'm talking raspi ARM type embedded computers here (like a cheap smartphone), so don't get too exited thinking is some super expensive device. A 25~100 USD addition to a 40k USD car would probably be negligible.

Why would anyone pick that particular altcoin over a thousand others that together have yet to surpass Bitcoin? We are talking about anti privacy Zuckerberg here, his mind can't possibly deviate much of that from a government: Centralization, control, and therefore, weak. He is too late to the game...

Let me tell you something: I predict this altcoin is going to be neglected hard. Almost all of them are. Facebook? pfff. Its actually a bad association, a minus rather than a plus.

The best you can do when promoting your altcoin, is projecting its technical merits, and leave the backers last. It tells me nothing Zuckerberg and Facebook are behind, but the white paper and source code does. What could they possibly add to the altcoin ecosystem to warrant any attention, beyond Facebook? If anything they are noobs, and have a bad history over the running of Facebook, hostile to Bitcoin, data mining, selling of user data, censorship, hacks, the story of Facebook is more something to be ashamed of.

I wouldn't be surprised Microsoft and Apple come with their little altcoins too.  Don't you notice there are too many altcoins? The best of them (alone) can't be considered a rival, yet.

What if he launched this 5 or 8 years ago? Then your excitement would have some merit, but now? Too late, the space is crowded. Want success? Adopt Bitcoin, or at least one of the best contenders into your platform before thinking of making "yet another one".

I see it as a means to obtain goods. After 5 years of hyperinflation, i lost any attachment for physical money, i don't particularly care if the transaction is electronic, if it has 1 zero or 8, its all meaningless. Its basically, the means of being able to purchase something you need.

And for me using satoshis or bitcoins is just as effective. Fluctuation? Meh, bitcoin is rock solid next to our garbage fiat. Every single day prices change under hyperinflation, so who cares bitcoin does the same?

Only people living in first world economies would, they just don't know anything else. I would feel weird not to check the new price of an item everyday. What, do you mean it remained the same as yesterday? Quick, buy it before it changes...

Under deflation, things are expected to slowly become cheaper, as in 2% annually. I expect something like this to occur in 50 years or so, when bitcoin fluctuates less and less due to reaching maturity. The fiat currencies are probably going to get weaker and weaker and start fluctuating, downwards, of course. The moment world economics start noticing and switch to Austrian school, abandon fractional reserve banking and reduce or remove all State intervention in the economy, finally embracing the way deflationary coin with actual voluntary money savings, the one YOU (optionally) pay banks to keep your money safe, and not the other way around.

Of course banks are going to shrink, but what money they declare becomes real and not like today where 90% of the "circulating" money is vapor. To make it simple: When bankruns cannot bankrupt a bank anymore. Like the bank of Amsterdam once had...

If you are 60amps you are small. My message is more meant for some of the monsters lurking the forum... You look fine indeed, compared to them. I think you have a bigger chance to survive than them, especially if you look into renewables, which is a long term investment (but no batteries please).

It is in their best interest to embrace it, and find ways they can profit from it too. Worst thing they can do is outright ban it, not only would they be repelling wealth from entering their country, people will find unregulated ways to keep using it anyway and no way to tax it. Even a neutral stance is preferable than outright ban.

There could be also a generational difference, among the politicians who act hostile or not against this new world reality. Want more profits and wealth? Embrace it, sooner than your neighbors, and see the money flow in...

If you are going to regulate it, STUDY it deeply first. I expect no less than the very Indian law makers asking questions on this very forum as a good sign of their seriousness. In fact more countries should be doing this.

Its not going to be proportional, even if it may look like that temporarily at first. You would be wise to start reducing your mining operation if you are already large (diversify your portfolio, invest elsewhere, or go solar/wind instead of pure asic mining purchases).

If bitcoin is 8k at the time of halving, don't expect it to go 16k next day, something like 12k or less would be about right.

That is without taking into consideration even more efficient miners rising that diff up. In the aftermath price might be even go down and kick a bunch of miners out (again). It is also wise to not spend everything, keep reserves. Don't live on the margin like most miners do, if you are unable to survive without a PPS pool administering your profits, then you are in trouble.

I think you are accurate to think the most profits will be made right before the halving, then assume some slump afterwards before things become attractive again, but not as much as the previous halving.

Funny to see Bitmain abusing their own equipment (or they don't care, lol). Horizontal placement hurts the upper board.

I'm also waiting for a full review, complete with: unboxing, web ui settings, power consumption, noise levels, tweaks for maximum efficiency and its respective parts disassembly

This is Cannan's first asicboost chip eh? My first immediate negatives would be: price, and the 30°C max ambient temperature. Its a good positive that they would (finally) allow simple LAN cables to be used, greatly simplifying setup (but is this still controlled from elsewhere as usual?)
