I guess you mean writing a custom script, correct?

Absolutely, I can also do that with my node, but automatic broadcast would mean that I wouldn't need to actually save the transaction anywhere. I guess I will have to implement it myself then.

Hey guys. I have asked this question again, but I can't find for some reason. I think it didn't have any answers anyway, so  I ask again.

Do you know if there is any way to create a timelocked transaction but broadcast it now and make it wait until the timelock? I am talking about an "automatic" addition to the mempool (somehow?) when the desired block has passed. I suppose it can't be done, because of the simple fact that there is nowhere that the nodes / miners could "save" this kind of transactions.

Wouldn't it be nice if there was such a feature? Do you think it would be bad for bitcoin to allow it? Or perhaps would it need radical changes to the way bitcoin works and therefore it can't be supported?

Bitcoin is a payments system by its genesis. The original paper is called "Bitcoin: a peer to peer electronic cash system". Lightning is a layer upon the chain of Bitcoin. It is connected to Bitcoin and can't live without Bitcoin. It requires proper bitcoin transactions to open and close channels.

Isn't it true, that the majority of nodes already have the majority of the next block's transactions in their mempool? Do we have an estimate or approximation of how many transactions already exist in the mempools and how many don't exist? Is it last second's transactions (in their majority)?

In this forum, advice is and always be acceptable. I don't claim you are a scammer. But people must be warned, because there are a lot of scammers out there. At the same time, you should be glad that he told other users to take precautions and use proper escrow tactics. Is there a problem with that? Escrows are mandatory in this kind of transactions.


How exactly will you check if the address is indeed held by Binance? Why do you want Binance address specifically. Did you mean to say "Bitcoin address"?

If not and you are willing to send first, then I am interested.

Indeed, but I wasn't able to find "pay with BTC" option, either on-chain or LN. Have you been able to find this option?

Perfect. Personally I don't want to bother with laminating paper etc. So I follow this approach: https://bitcointalk.org/index.php?topic=5466510.msg62910792#msg62910792. It is also kind of waterproof because of all the packaging. However it's not fireproof. But as we said, I am not afraid of the fire since I have 2 backups in separate places. And the chances of both those places burning up at the same time is tiny to non-existent.

I don't have an answer to your question since hardware failure depends on the hardware. I reckon it shouldn't be only 2-3 years but much more. I have no proof to justify my words though.

However, you shouldn't worry about it, since you can have a dual backup of your seed phrase and then you don't really care if the wallet (device) loses data. In fact, you can even destroy it and don't lose anything at all, as long as the only thing required to retrieve the wallet is your seed phrase and your passphrase (optional).

Personally, I have set my device to "temporary signing" meaning it erases memory when shutdown. So I use the "malfunction" that you ask for, as a feature!

I will sound stupid, but does the coin have the private key engraved upon it or somewhere else?

I think the number one rule that exists in investing is not "diversification" but rather "know what you own". Owning small altcoins just to make profit is gamble, unless you have strong fundamental conviction on why those altcoins are superior to other tokens. The same applies to stocks and fiat currencies.

Personally, when I buy an asset, I try to ask myself "why I think this asset will give me more financial freedom in the future?". I have extremely high conviction in Bitcoin for multiple reasons and I am a Bitcoin-only holder but! this doesn't mean I don't own other assets. Of course I do, but not from the cryptocurrency world. Diversification is indeed important, but buying altcoins doesn't mean you can diversify well enough.

Another point to be made is that most altcoins exist on Ethereum's blockchain. Here is a list: https://cryptoslate.com/blockchain/ethereum/. This instantly gives super power to Ethereum, which you must never forget, is PoS, meaning the highest bidder can change the rules.

Bitcoin Core is indeed a wallet, but is much more than that.
Bitcoin is a blockchain (list of blocks). Every single transaction that has ever happened is stored in this blockchain.
Let's say that I want to send you X amount of BTC. Bitcoin is digital, so I could fake it, right? Wrong! Every computer that runs Bitcoin Core, can download a FULL copy of the blockchain and have their own opinion to whether I have X amount of BTC to send. In order for this to happen, there needs to be a concesus (from the computers running Bitcoin Core) in regards to whether I really have this amount and I am not just faking it.
In fact without Bitcoin Core, there can be no Bitcoin. Even if you don't run Bitcoin Core (which is totally possible), you will need to connect to someone else's computer. So you need to trust THEIR opinions and at the same time, you lose privacy.
Bitcoin Core, also provides you with a wallet, as I said.

So, if you don't want to download Bitcoin Core and since you mentioned mobile device, you can download BlueWallet or Blockstream Green or any other wallet that other users suggest. These wallets will provide you with 12 or 24 words that you need to keep safe (offline) and away from anyone else. It is your wallet's backup. Losing it results to losing all your coins. If someone steals it, they can steal all your coins. Those wallet will connect to someone else's computer that runs bitcoin core.

A good tutorial for BlueWallet is here: https://www.youtube.com/watch?v=imMX7i4qpmg&ab_channel=BTCSessions. I suggest that you stop watching where he starts talking about Lightning because, for the time being, it will only confuse you. We will be here to discuss Lightning in the future.

I know you just started and it may sound difficult, but you can of course re-think my post after a while.

I use black ink and thick paper (300gsm) and I put it in card sleeves (like these https://www.amazon.com/s?k=card+sleeves&crid=QHQWRBIWB1WW&sprefix=card+sleeves%2Caps%2C196&ref=nb_sb_noss_1). I used to have a lot of these cause I used to play trading card games. Then I put the sleeves in zip plastic bags (like these https://www.amazon.com/Reclosable-Resealable-888-Display-USA/dp/B07V5R9CV2/ref=sr_1_2?crid=24D690NZRCAGX&keywords=small+zip+plastic+bag&qid=1695835517&sprefix=small+zip+plastic+bag%2Caps%2C176&sr=8-2). Finally, I put them in bubble mailers (like these https://www.amazon.com/Quality-Park-Envelopes-Redi-Strip-QUA85755/dp/B08QZCY3KY/ref=sr_1_1_sspa?crid=K04CYNKFIIX8&keywords=post+bag&qid=1695835568&sprefix=post+bag%2Caps%2C184&sr=8-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1). Then I put them in secret places  I revisit them twice a year to make sure they are ok and once a year I rewrite them.

If you 've ever thought you knew what insanity is, please reconsider 

Hi guys. I have no idea in regards to mining, but I am willing to learn. I checked this website: https://minetheasic.com/?BTC

I saw that with an estimate of $0.1/KWH the S9 is actually losing money instead of earning. Am I correct?

I am following your conversation and without wanting to add something to what other users already said, I thought the following image could be helpful.

This is why I back them up. I was born in 1994. If my passphrase was 1994, why would I bother backing it up? I mean I can safely assume that I will remember it. As a software engineer, but more importantly as a rational person, I can state that on the internet there is no such thing as "100% security" or "100% privacy". We can only try to diminish single points of failure and avoid silly mistakes. We can educate ourselves to think calmly and rationally. If I have a single backup (in the strongest material of the world), if I lose it, I am done... At the same time, if I have two backups at the same geographical place, it's stupid. I know these things are trivial and super simple to realise but I come across people that don't understand them. A friend of mine told me the other day that he had two backups of his seed phrase, in the same drawer. He said "two is better than one". I felt I had to explain the simplest thing, but apparently I had to do it. He also had his passphrase backed up in the same drawer all together. The back up was something like "my birth year". Anyone who stole this paper could just try all the years from 1923 to 2023 (assuming he is not older than 100yo and not younger than 1yo ). Just observe how many mistakes were made by my friend, that have nothing to do with Bitcoin, but it's just common sense.

But, at this point, I would like to merit you personally, because you have helped me a lot in this journey. And LoyceV too. As I have stated in other threads, I also have a multisig vault. The backing-up idea of the XPUBs in a cyclical manner along with the seeds wasn't so obvious to me at first, but it is a great idea after all.

What I try to say with these two paragraphs is, we must think rationally. Establish the proper precaution measures, that are trivial to everyone. Then, take small steps to ameliorate things even more.

My review for the service is here: https://bitcointalk.org/index.php?topic=4966853.msg62908042#msg62908042

My Experience
So, I fired up TOR and pasted this link: http://[banned mixer]/

I was presented with the following page:



I chose to mix my coins (not the free option).

I was presented with this page:



I added my desired receiving address and I did not enter a secondary address.

There was minimum limit to the amount of sats I was allowed to send. It was 300k sats. I sent a little more than the lowest amount.

I received 2 UTXOs at random time intervals (one in the first hour and one after 4 hours). The amounts were also random. However, having added one address only, I got both UTXOs to the same address.

My Thoughts

• I wanted the system to allow me to add more addresses and choose the amount of UTXOs to receive. I should be able to receive all UTXOs in separate addresses for privacy reasons.
• The fact that the time intervals and the amounts are random is very good.
• The whole process was super easy. I was surprised by the convenience and ease of use.
• The total time of return is up to 6 hours. Perhaps it could be also decided by the user. The website could provide some options (i.e. 3hrs, 6hrs, 9hrs etc) and the user could choose from these.
  

In fact, I have lost money before. I have opened a relevant thread. It didn't matter how well I had backed up my wallet. I made more severe mistakes.

Having two backups is vital. We don't discuss about this actually. The only wallet for which I have no dual backup is my multisig vault where I have the necessary redundancy with 3 cosigners backed up once.

Finally, I also have two backups of my passphrase. I don't trust my memory at all. So I have 2 wallets (2 seeds + 2 passphrases). I have backed them up as follows:

Place 1: Seed A + Passphrase B
Place 2: Seed B + Passphrase A
Place 3: Seed A + Seed B
Place 4: Passphrase A + Passphrase B

Losing 1 packet, I have no problem. If an attacker steals 1 packet they cannot take my funds from any wallet.

Even losing 2 packets, I have a small chance of not losing all my money.


It is the last thing I will worry about. It must be devastating, seeing your house on fire.

Yes, that's what I saw too.

I think when it comes to corossion resistance, then Grade 5 is the winner.

When it comes to heat, I saw this on the internet:

Metal	Melting point (C)
Aluminum	660
Copper	1084
Stainless Steel	1510
Titanium	1670

I guess that according to titanium grade you can only go higher than 1670 Celcius.

Anyway, according to Wikipedia there are 38 grades for Titanium alloys, so.........
