I bought some shit coin and every time I try to swap it and get it out of my coinbase wallet, it fails. Any advice?

Hi All,

I have been using an online movie website for 18years now. They have recently changed their payment method to bitcoin and offered a way to purchase it through a 3rd party rampswap. I tried to do this but my bank declined the payment twice and blocked my card. I then tried to open up a Revolut account and thought this might work however they restricted my online banking and I spent ages on the phone tk the fraud squad convincing them I'm not some victim 😑

Can anyone advise a way around this? I contacted the website and they haven't helped.

Hi all,

I need advice on how to start investing in BTC starting today. I could buy BTC for 10k right away or DCA it, then afterwards DCAing with 500€/month. Which strategy would you recommend:

1. Invest 10k right away then DCA 500€/month
2. DCA the 10k in the next couple of months and the DCA 500€/months.

3.?

Thanks in advance!

What sites have you heard of?

So I have a couple of cool uncles who've invested in a few cryptocurrencies.. How do I ask for bitcoin as a christmas gift? So far I have a very small amount invested in bitcoin in Kraken.

When I get to the park in my up hole, it asks me for my address and I can never get the address part to go through. It always says my postal code or something’s wrong. What’s going on?

Where do u guys save ur 12 or whatever words?

Ik u save it in a paper or metal. But i mean where do u put that. I want to know ur ideas

As i am paranoid i want to create a new 12 word secret. It's probably bullshit but the guy who helped me create my first wallet was an extremely smart guy. Now my anxiety worries he remembered my 12 words and wrote them down later.

So, i have a new phone. Install a new exodus app. Create a brand new 12 word secret and more my bitcoin between the old and new wallet..

And now i have peak anxiety. First thing i think of is unplugging my google next hub, my Sonos boxes wich support speach and generally hide in a supply closet where no 'smart devices' can hear me. But my phone does....

I think EVEN if i disable all my speach support Google is an asshole and listens anyway. Just like it doesnt 'share' my whereabouts'. Or one of my apps had a secret backdoor.

I intent to eventually invest 50.000 euro or more in bitcoin. So yes the thought of someone stealing them worries me. I am thinking of buying a Ledger Nano S Plus. To keep them offline. BUT i read that in the case my Ledger Nano dies (Like, hardware failure) i don't lose my bitcoin. But that with a 12 word secret prase i can ALWAYS get my bitcoin back.

So. How can i be 100% sure my account is save. A mechanical voice reading 12 words aloud seems to cream 'Insecure' to be. I think 99% of the people forget Google/Alexa/Smart devices are listening and recording. Not to mention your phone if listening and recording. What is stopping a hacker gathering a lot of word lists for a new months/years and then BOOM. Becoming a multimillionair.

How would you advice me?

Hi all. Exchanges always confuse the hell out of me with their fee structures. I'm thinking of transferring my btc from my Wealthsimple account to NDAX so I can sell it when the time comes at a 0.2% fee instead of 2% with Wealthsimple. In theory, this seems to me like a smart idea but I cant help but ask just to make sure. For context, I'm Canadian which is why NDAX is the exchange I'm considering.

I've started using the Crypto.com app to send BTC to friend of mine and I'm being told that what I send is showing up $40 less than I sent. Has anybody ever heard about something like this?

Is there another app you all could suggest for sending BTC?

Thanks,

First, is there a good beginner's guide somewhere? Reputable content in YouTube? I'm gonna Google and stuff but would appreciate insights from people who know what they're doing.

When: Should I jump in now or wait to buy till things cool down?

Where: I'm very new to this so have a lot of questions about where to buy. I see places like Coinbase, Robin Hood, etc. What factors should I be considering in making this choice? As a beginner does it make sense to get my own wallet vs using another service?

How much: I'm looking to start start small, not more than a couple hundred dollars. Does that affect the decision of where to buy?

What else: Anything else I should think about?

Hey,

I found an old core wallet and I suspect that there might be a small amount of money in there. I can't download the whole blockchain again. It takes forever, crashes too often and is just unreliable.

I read that I can import it into Electrum, but I'm worried of losing my funds. I know that there's something called sweeping, where Electrum takes in the private keys and creates a transaction moving all funds from the private keys it got into the current Electrum wallet. That feels spooky. Usually I would do a test transaction and if it succeeds I would move all funds. Just letting a "blackbox" handle everything seems wrong to me.

Now I read that I can also import the keys and just overwrite my Electrum wallet with it. I would lose some functions of Electrum then, since I won't have a full Electrum wallet, but I intend to move the funds elsewhere anyways.

Can I just do the latter without worrying about anything? I don't want to mess this up.

After companies and countries FOMO into it, what's the next big move for Bitcoin? Like any other investment, people buy it because they believe it will go up more in the future. After it becomes mainstream for countries and large companies to hold some, why would it go up more?

If I were leading a Fortune 500 company or a country, I would be worried that it won't go up more after this nation-state adoption stage.

I hope I'm wrong. I'm new to BTC and bought .05 BTC a few weeks ago and am about to by another .05, but I want to hear some good arguments for its continued value so I can sleep well not feeling like I am just part of a greater fool's game.

I'm seeking ideas for games involving sending/receiving Testnet Bitcoin?

I'm gathering some noobs to show them how to send/receive bitcoin.
Once we issue a coupla transactions, I was thinking it might be fun to turn it into a game to increase the learning.

We're using Blockstream Green wallet to do this because it has an easy option for Testnet (thank you to r/Bitcoin for teaching me this).
I'm prepared to send Testnet Bitcoin by virtue of these faucets:

Hello all,

I want to preface this by saying I got really into Bitcoin during COVID. I bought a hardware wallet (COLDCARD Mk4) at some point and set it up and then imported to Bluewallet to watch my balance.

I'm trying to be a little more serious about it now after life got in the way and I'm testing the wallet to make sure I can move my funds for when I need them. I withdrew some sats from Swan where I had some bitcoin to withdraw using the xpub from my COLDCARD and it never showed up in Bluewallet. First red flag.

Then, I tried sending some funds from the wallet to test it and after creating the PSBT, the COLDCARD cannot validate it and I get this error: "Failure: Missing redeem/witness script for output #1"

I did a little digging but came up empty. I also tried re-importing the wallet according to Bluewallet's instructions and it created another COLDCARD import, but the public keys on the new wallet start with bc and the public keys on the existing wallet start with 3.

I'm really trying to make sure I have access to all of my funds. I'm wanting to eventually use it for our wedding and I'm frankly feeling a little unnerved right now that my funds are locked up with no way for me to use them.

Any help would be greatly appreciated since I don't have the technical knowledge or time to be able to work this out. I think keeping my own keys requires me to better understand everything before moving any more funds.

On kraken app i can buy bitcoin with euro currency but on kraken pro it only shows me USD can't buy with euro, and i already changed the currency from USD to euro... any suggestions?

So I am learning about p2sh scripts as of late, I saw many examples online, I understood them but the redeem script is where I am confused. For example this simple script "OP_DROP OP_1", = 7551 The solution: "OP_1 OP_DROP OP_1" =517551 but when I submit the redeem script online, I get an error, please correct me where I am wrong or what am I missing ?

Hey everyone! I’m new to Bitcoin and looking for a trusted exchange with low fees for buying and selling in small amounts (around $20 per transaction). I want to keep costs low as I’m just learning. I’ve started with Coinbase but heard about Swan and Strike too—does anyone have experience with these, or is there another platform you’d recommend for quick, low-cost trades? Any and all recommendations welcome, thanks.

Hi guys. I'm planning to invest a 100$ in bitcoin. This is my first time investing in bitcoin and I need your advice. Is it worth it to invest this small amount and earn?

Help a beginner out.

Basically the title. Sent a small amount of sats to my hardware wallet as a test (about 5 dollars). It shows the transaction as completed in history but the available amount is still zero. Can anyone help find out what could be happening? (I'm using Trust Wallet)

Excited to be a part of this now! I know the market is up right now, but Dollar Cost Averaging (DCA) is important according to all the talk on here and amongst the research I've done. The opening thread to this page ( https://www.reddit.com/r/BitcoinBeginners/comments/g42ijd/faq_for_beginners/ ) as well as the one on r/Bitcoin was super helpful with understanding wallets and general concepts behind the use, application, and theory of Bitcoin.

Moving forward, I’m interested in hearing what exchange people prefer to use and why. Is it just fees that you look at, or is there a preference out there?

Also, wallet use seems a bit daunting for someone new to the crypto scene. How often do you transfer into the wallet? Do you wait to reach a certain amount? I'm assuming this is just preference. Any other advice appreciated!

Thanks all!

What would be better for solo mining with a BitAxe Gamma? I heard that on solo.ckpool 6 blocks got lost in the past, is that correct and if yes, is there any information why that happened?

I bought and I will add every week. Is this a good idea?

Like right now, without any forewarning?

I've added a passphrase to my Jade. I picked a phrase I'd remember, and the words aren't on the BIP39 list. Anyways, if I want the security of a passphrase, do I have to type in this whole phrase using the tiny little Jade keyboard? Is there anyway I can benefit from the additional security of a passphrase without having to type the bast@ard in everytime I log in to my wallet?

To give some context, I am in my 20's, and I want to start an investment that would be long term within the realm of BTC. Whether I should go down the route of a lump sum now, or commence down the route of DCA is to be determined upon informing myself properly. I am completely new, zero experience in investing, zero experience in cryptocurrency. I had a fleeting thought to invest a few years ago (should have, but the best time now is tomorrow). I want to make an informed decision myself, though if anyone has their own views on whether I should buy ASAP (lump sum, or commence down the DCA route), I would happily take all advice and consideration. Or if I should potentially wait for a potential fall after this ATH (though how can one predict what is above when we can only see what is below).

I would really appreciate if you could share some YouTube video creators, playlists, podcasts, anything/anywhere that I can spend some hours/days really informing myself about how everything works. Where to go and study trends, understand the trends, everything and anything.

I don't want to miss out on what I so far believe to be a credible long term investment.

I hope you are keeping well and best of luck with your future, love from Ireland.

I brought 100 eur worth bitcoin and now it is 350 euro. Feeling sad I didn't buy much. Today I am going to buy a bit. Which platform is best? Is it too late now? 😢

Thanks in advance for any help.

Sparrow Best Practices guide says:

Bitcoin Core stores your public keys and balance unencrypted on the computer it is running on. If this computer is regularly connected to the internet, it is at risk to hackers - which will make you a target once your balance is discovered.

Not only hackers, but also burglaries. Someone might home invade you for your private keys after learning from a broadcasted transaction (from your IP address) that you are sitting on a fat stack.

With this in mind, the Sparrow guide recommends running an Electerum server from your own node. However, isn't this still standing out to attackers? If an attacker sees someone drop $200+ on setting up a personal Bitcoin node, they've probably got a fair bit of bitcoin to justify the expense.

How to avoid? Only broadcast transactions from a burner laptop using your local library's internet?

I have been studying Bitcoin's transaction processing and thinking about concurrent handling in distributed systems. Is anyone here familiar with how different languages handle this at scale? Particularly interested in functional approaches vs Bitcoin's C++ implementation
