What exactly is a node? I’ve heard the term a lot, but I’m not sure what it really means or how it fits into the Bitcoin network. ChatGPT gave me a relly bad explanation, so i would appreciate a better one!

I am not "new" because I mined BTC 2013/14, but very inactive again till now except for ETFs. Thankyou Cathie Wood for the 8X!

Anyways, I always used Bitcoin Core etc and just setup my first hardware wallet. My question is does the passphrase only protect the hardware wallet itself or is it a factor in hacking the block online? I never totally understood how it all works at the time, I just mined out of curiosity since the price was only $50. Once it hit $200 and $1K then I was interested from an investing standpoint. ;-)

Hi 👋, looking for what bitcpin miner to buy. I've got 10 kW peak capacity of solar power that I produce during summer. In winter it's 3kw.

What bitcoin miner do you recommend? I'm happy to invest 2k usd. My main goal is to make a profit and considering to only run during the day.

Im kinda new to this game. I have 0.01BTC in Fidelity. Should I move to Coinbase? Whats the difference of the two?

never bought Bitcoin, going to be my first time, I'm studying it. should i buy non-KYC BTC? and if yes, on binq or RoboSats? idk

I'm from SA (not from US or EU)

ty

What is the best exchange for buying bitcoin in the EU?

What do you think of holding bitcoin on a Robinhood account? How risky is it?

There’s 8.2 billion people on earth and only 21 million bitcoins. How can it ever become a universal currency if there’s not even enough for everybody to have one.

Hi complete newbie here. I have a non custodial wallet created in okx with a 12-word seed phrase. I kind of don’t want to use okx anymore but don’t mind keeping the wallet so I’m thinking about importing it to blue wallet. Here are a few questions:

1. Can a wallet exist in different apps at the same time?

2. Does importing create additional security risk? Is there a trace of my information on both okx and blue wallet now giving hackers more accesses to steal my information?

3. If you can move the same wallet between any apps/softwares, what does it matter which app you use?

Thanks!

Hi,

So I have a Ledger Nano S and I created a 24word seed phrase. I changed the order of some words which I can remember.
Then I have written this changed seed phrase into my Password Manager (KeePass XC).

Is that safe, as long as I use the password manager correctly?
I think, even if someone gets my "encrypted" seed phrase they have 24! different options to "crack" it. So basically impossible. Is that correct?

I have Blue Wallet with two wallets. One of them is watch-only but I can’t remember what I set it up to watch! It is showing an amount but a different amount to the other wallet! How do I find out what it’s watching?

when i made the wallet, bitcoin was still relatively new. i have literally zero idea if there is anything in the wallet. but now i'm just kind of a boring wealthsimple user, at best. how do i check this old wallet for bitcoin?

I want to make sure I haven’t compromised my keys or crypto - anxious person trying to do the right thing (cold storage, never divulge seed phrase or keep digital copies, etc) and always scared I’m going to fuck up somehow so please read and bear with me.

I wanted to take some BTC profits so I did my usual thing with my ledger. I noticed that the transaction was still pending after 15 mins. I know that this is normal especially when there’s high traffic but I decided to go a bit deeper and see if I could speed things up to kind of upskill my crypto skills but now I’m worried I’ve done the wrong thing.

Anyway after a bit of research I find electrum. Ledger has a guide on it to speed up BTC transactions and a quick vet of reddit and the website itself looked good. I followed ledgers guide to download and instal. I was on the electrum.org site and the .io documentation site but I did not verify the download (I see some of you suggesting to do that) . I connect my ledger (without putting in any passwords or phrases) and start the process. Initially I run into some errors when trying to sign to increase the fee. I click sign on electrum but an error message appears and and I don’t think I get to confirm on my ledger. After a while I refresh explorer and realise the transaction has now been confirmed once. I’m assuming this is why it didn’t work but I’m not 100% sure it was confirmed the whole time I was trying?

A quick check and BTC has gone where I expected it to. I force quit the application and it says it has quit unexpectedly. Then I can’t find it in my applications only in ‘locations’ where I can open or eject it? I use Mac so maybe this is because it was an executable file and I didn’t drag it into applications? Anyway at this point I’m freaking out.

Have I just compromised my crypto? Can connecting my ledger to electrum give out my keys? Is there any danger here? I’ve moved a little more since with no issue but just want to check in ok.

I really like ledger, so i'd like to buy one. The nano X would be 100% fine if not for the fact that i basically do every crypto trade on my iPhone. again, i don't have much in crypto but i really don't want to loose the one I have, which as of writing this sits in coinbase and a bitcoin ETF in Schwab. I have somewhere in between 2-10 k to put into crypto. thank you for your help

Say I have a small amount of btc on a soft wallet on my phone that I want to transfer directly to my cold wallet device. Would the transfer need to go through an intermediary of some sort, like an exchange? Or could I simply click on “send btc” on the soft wallet app and put in a public address from the cold wallet? Thanks much

I am having the same problem described in [this post](https://www.reddit.com/r/Electrum/comments/16tkh0y/create\_wallet\_command\_did\_not\_work\_electrum). However, their solution is not working for me.

I am running on Windows 11 Pro, and I followed [this guide](https://driftwoodpalace.github.io/Hodl-Guide/hodl-guide\_63\_eps-win.html#setting-up-electrum) linked to by [the official electrum-personal-server repo](https://github.com/chris-belcher/electrum-personal-server).

When I run EPS, I see the following output in the terminal

```

INFO:2024-11-29 15:15:47,641: Starting Electrum Personal Server 0.2.4

```

The process seems to stop there, and nothing happens.

I have Bitcoin Core running, with a wallet of its own (different from the wallet I created in Electrum).

I've spent a few hours trying to troubleshoot this and I'm not really sure what I'm missing.

Any hints or tips would be greatly appreciated!

I've found a small amount of BTC in an electrum 2.7.9 wallet on an old laptop. It must be from around 2017.

I just opened a blockchain.com account to transfer the money into.

When I try to send the BTC to my new wallet, it says "invalid address".

How do I navigate this?

How did people update their wallet.dats in the beginning? I feel like there were so many crashes or bankruptcies from online wallets. I know that paper wallets became useless at some point. If you wanted to maintain a cold wallet was it just saving the software itself on a hard drive?

Why is this company talked about in other bitcoin forums ? Would you invest In this company over bitcoin?

Hi all, I am new to crypto investing as most people who post on here. I have ordered a trezor but have not set that up yet. With my research I have seen people mention about benefits of a computer that is dedicated to crypto transactions only, air gapped, etc. What I am trying to understand is if any of these can be combined for the best security or if they are alternatives to each other.

Can Trezor be air gapped?

Will I benefit if I get a dedicated computer solely for trezor and crypto transactions? If so what basic computer would be best?

Is having the trezor and trezor suite a replacement for air gapped, dedicated computer.

Any other similar combinations or alternatives?

This would be for long term cold storage.

Just stumbled on this one. I don't think I've ever seen such a thing.

Edit: suggestion is that it's a burner address

Coldcard + Sparrow (Desktop) - SD card is needed for sending/signing?

Coldcard + Nunchuck (Mobile) - NFC or QR code for sending/signing?

If I want to stick with 12 words, is the "roll dice" seed-phrase feature a nice touch? If so, how many rolls?

I couldn't justify the $40 micro SD card from Coinkite so will order off Amazon. Any recommendations for brand, storage capacity, speed class?

Would like to hear from Coldcard owners, if possible.

I've spent a few years trying to complete some financial goals, and I'm finally at the point where I'm looking to invest 5% of my annual retirement investment in Bitcoin. Mostly as an "invest and forget" type deal. Where my intent is to just buy into it consistently and hopefully come out well ahead in 20 years. But if it disappears, it won't ruin me.

The way I invest with after-tax brokerages is that I like to DCA every weekday partly because SoFi makes it very easy to do so (I can basically just set up a few automated recurring buys to buy $X worth of VOO every week day).

Is there any way to do this with BTC? Will the fees make this an absurd way to buy into BTC? I'd go down to once weekly, or once monthly if needed. Recommended brokerages? My biggest priority is security, then automation. Is it okay to leave it in coinbase (or whatever) or should I pull it out after X amount BTC? Hard wallets seem a little scary, but maybe just keep the drive in a deposit box and the seed words in another bank deposit box? Or something? It's scary because it's basically like, "here's $10,000 (or whatever) right here". I wouldn't want to hold that much cash in my house.

I wish I could get into BTC via an ETF, but I bought into BITO when it came out (when I was very loose with money), and it's still down like 40%. If I had bought actual BTC at the time, it would have 2x'ed...

Context on weird DCA behavior: I DCA like this because half of my comp is paid in stock twice a year, so I DCA out a portion of proceeds from the stock vest until the next one. It helps me to budget and I like that the cash can collect interest in HYSA until it gets invested. It also is a bit of padding to our existing cash emergency fund.

can someone help me? I am trying to learn more about lightning network.

I invested $7k a few months ago into Bitcoin on Robinhood. It is now at $14.2k. When I try to sell the maximum value, it shows $10k. Why is that? That is over a 4 thousand dollar difference. Hoping it’s not for fee/commission because that would be ridiculous.

Any info on this appreciated, thanks.

I just finished setting up a Bitcoin Core node. I enabled incoming connections on a given port.

However, when I use my IP:Port in the Electrum Mobile Wallet, it seems to be unable to connect.

I keep reading things about using or needing Electrum Personal Server.

I'm having a hard time understanding the role of EPS in all this. Do I really need it? Can't I just point to my current node?

Estou buscando me informar sobre BTC, por onde devo começar? Agradeço de coração a quem puder me deixar algumas boas recomendações de onde posso me aprofundar no assunto, seja por livros/vídeos/blogs/etc...

OBS: Pode ser conteúdo tanto em inglês quanto em português, meu inglês é meio fraco, mas aceito recomendações mesmo assim. :)

Desde já agradeço!

When i first started crypto, i was all over the place. I have one transaction where I can't seem to figure out where I sent it to my self from. Is there any way to find out? I sent it to myself on coinbase. Just trying to solve this mystery

Hi all.

I've been DCAing on BTC for a little over a year now, and I've been doing so through Binance.

Not that it is relevant for this question, but I usually send 1000€ at once (to minimize deposit fees), DCA that amount for the next 3 months, send the btc to cold storage, and then repeat the process.

Now, to my question: whenever I go buy some sats, I check on the current btc price and it always differs from the one I end up paying for.

For instance: right now I did a test in the Binance app and the current price of 1 btc was around 90250€. When I went to the convert section and tried to convert a few € into sats, the price of 1 btc was stated as being 90750€, even thought there were no fee costs on this conversion.

Can someone explain what is this difference in price? Is it some kind of disguised fee or something?

Also, does that happen in other exchanges like Kraken? I've been thinking on switching to Kraken for a while now.

Thanks everyone.

Hi Everyone,

I know this topic has likely been covered extensively, but I would really appreciate your insights. I've had a growing interest in crypto for some time, and now that my financial situation has reached a point where I can allocate funds, I’m looking to invest in a mix of stocks, Bitcoin, and a small portion in other cryptocurrencies (probably like $100-200 to crypto a month).

That said, I’m looking for recommendations on the best exchanges for trading Bitcoin and other cryptos, particularly ones that are approved for use in Canada (not necessarily Canadian-based). While I’m not sure I’m ready to manage a cold wallet yet, I would prefer to rely on the exchange for custody of my keys, with the flexibility to transfer to a cold wallet down the road if needed.

Here are the key factors I’m looking for:

• High liquidity and trading volume
• Safety and regulatory compliance
• Reliable crypto key custody with the option to transfer to a cold wallet in the future
• Reasonable fees

I plan to do my own research as well, but I’d greatly appreciate any recommendations or insights you can share at this stage that could direct my analysis / research.

Thanks in advance for your help!
