1241  Other / Beginners & Help / Re: How do you come up with reliable predictions for prices? on: June 27, 2023, 02:12:07 PM
Why not start to learn how to read candlesticks? That should be the first thing you need to learn for technical analysis to predict the next price movement you can check this link below

- https://academy.binance.com/en/articles/a-beginners-guide-to-candlestick-charts

Also, I suggest to join on Binance Academy because they have lots of strategies that you can learn.

Another source is where you can start to learn how to trade is this link below you can almost see all tools there free and paid and they do also have lots of courses that you can read for free.

- https://github.com/SpiralDevelopment/Awesome-Crypto-Trading

Once you learn from that source don't forget to test the skills and strategies on the trading simulator(listed from that source for free)
1242  Bitcoin / Mining / Re: Minning on: June 27, 2023, 10:41:19 AM
Mining without any hardware? That's not possible at all.

Take note that anyone claiming that you can mine bitcoin without any need to hardware and just with going to a website, running an application, etc. is a scammer.
There are also services called cloud mining that claim that they sell you mining power. They are scam too.

Actually, there are still some legit seller who sells hashrate check the list below

- Nicehash
- MiningRigRentals
- Binance Cloud mining

Currently, only those 3 that I know legit who sell hashrate but Binance hashrate is sold out.
The only problem with buying a hashrate we do not know if it's profitable or not because they also ask for maintenance and electricity fees.

if i may ask, what's the least affordable price of a mining hardware

If you are looking for an affordable price you can buy 2nd hand units like Antminer s9 only if you have a very cheap electricity rate or have free power. Because old Bitmain units are not profitable unless you have free/cheap power.
1243  Bitcoin / Development & Technical Discussion / Re: Which oparating system distribution for hosting a Bitcoin Core node? on: June 27, 2023, 09:21:25 AM
Ubuntu Linux is the best to run a Bitcoin core node because they have a large community, it's secured and is way more stable than using other OS.
This means you can get more support if you experience some issues while running a full node.
1244  Bitcoin / Development & Technical Discussion / Re: JSON-RPC spec for Wallets on: June 26, 2023, 11:51:37 PM
With a little bit of research using Google you can find them.

Anyway, check these links that I gather from Google these might be what you looking for.

- https://en.bitcoin.it/wiki/API_reference_(JSON-RPC)
- https://developer.bitcoin.org/reference/rpc/
- https://github.com/bitcoin/bitcoin/blob/master/doc/JSON-RPC-interface.md

If you don't mind can I ask if you are planning to develop your own wallet?
1245  Other / Meta / Re: Captcha slow to load on Safari browser on: June 26, 2023, 03:26:32 PM

I preferred because it’s smooth to use and I’m comfortable using it for my iOS gadgets.

Can you tell us what exactly IOS gadget you use when trying to load the captcha?
Also, tell us what version of Safari browse.?
And maybe you are trying to access the forum with an outdated IOS device or Safari.

I search a bit and it looks like the Safari browser has some bugs related to the captcha like slow loading or captcha that doesn't load properly.
So I think this is not a forum issue it's your device issue that might need to be fully reset or it needs to be upgraded to the latest version.

Never heard that there is someone being hacked by connecting to your own router and internet. By default, the router is set to a high-security firewall.
So it is safe than connecting to public wifi unless there is someone who is also connected on the same router and has permission to your device then he can retrieve data from your device or without permission maybe he can able to brute force and retrieve data from your device.
1247  Economy / Trading Discussion / Re: Marketplace to sell gift cards with bitcoin with low fees on: June 26, 2023, 07:08:48 AM

i'm already registered but i think to be a seller you must have an LTD or an LLC not sure , i just remember that i didn't fit the requirements(sadly)

Are you verified? It requires KYC and it looks like they also ask for business verification that requires some documents listed in this link below.

- https://supporthub.g2a.com/seller/en/getting-started/business-verification-and-business-accounts-on-g2acom-marketplace

If you can provide those documents there you can be a seller.
1248  Bitcoin / Bitcoin Discussion / Re: Can you only have a receiving address pay send bitcoin? on: June 25, 2023, 11:53:13 PM
That's the problem with using safepal wallet they don't have yet Coin control feature so if you received many transactions into your Safepal wallet and made a transaction all of your BTC will be sent to where you want to send it and to your changed address if available but it looks like they don't also have this feature so the change would send back to your wallet address.

Another problem is this wallet does not support other wallets like Electrum the guide shared by bitmover should be useful if Safepal support it.
What you can only do if you want a coin control feature is to export the private key from Safepal and then import it to Electrum.
1249  Bitcoin / Bitcoin Discussion / Re: Is it true that if you bounce bitcoin back and forth to different wallets on: June 25, 2023, 11:34:38 PM
Not all transactions that you made even if you have 100 different wallets they recorded on the blockchain explorers but it would increase your privacy if you split the amount into different addresses. Meaning it's hard for them to know if you still own the wallet addresses where you sent BTC but it is still traceable.

If this is the case then they should give another note or requirements to ask their users but in OP's case looks like it isnt.

@OP try to message them in weekdays if they will give a useful response.
If I'm right he is the same person who made a topic on reddit a few hours ago from this link below he already got a response from Coinbase support but the OP can't provide a Case ID to follow up his case.

1251  Bitcoin / Bitcoin Technical Support / Re: Please Help! New Bitcoin Core node user - Getting fatal error when restarting on: June 24, 2023, 03:10:22 PM
Based on the logs provided by Cricktor above it seems you didn't close or shut down the Bitcoin core properly which cause some of your Bitcoin core data on an external drive to become corrupted.

-reindex might fix this issue the easy way to run this flag alternatively from the suggestion above is by adding -reindex on the Bitcoin core shortcut properties you can check the image below where you can add the -reindex.




Is there another way to know if Bitcoin Core is really shut down? Should I be inspecting my task manager to make sure?.

Yes, it would be better check the task manager if bitcoin core daemon still running on the background you might need to use bitcoin-cli stop command to properly shut down your node.

And to know if it's properly shut down you will need to use this command below

Code:
bitcoin-cli getblockchaininfo
1252  Bitcoin / Mining / Re: WIFI on Antminer S5 on: June 24, 2023, 02:40:55 PM
Will running WIFI on an Antminer S5 cause a decrease bitcoin production? I was looking at using a Linksys EA3500-NP configured as a wireless bridge.
Unstable wifi can cause the miner to stop mining but if you can keep it stable and low ping then it won't affect your mining shares.

About the Linksys EA3500-NP, it looks like a router but if it supports a wireless bridge then you can connect it through wifi.
Why did you choose this router instead of buying wifi extender with an ethernet port?

It seems that you're not the only one who had some issues using Coinbase over the past few days check this Reddit post below

- https://www.reddit.com/r/CoinBase/comments/141ekq8/are_your_buys_disabled/

It seems they become more strict in regulating users after being sued by SEC. So I think this is just their security procedure to follow the SEC rules and regulations.
1254  Bitcoin / Electrum / Re: Old Electrum wallet - 3.0.6 on: June 24, 2023, 12:35:51 PM
I suggest instead of upgrading it to the latest version without removing the old version better uninstall this old Electrum and delete all Electrum folders and files in appdata and after that do what they suggested above download the latest version and then verify GPG before you install.

I just suggested it to avoid some error or corruption issues it sometimes happens when your Electrum version is too old and then upgraded to the newest version but before you do it make sure you already have a backup seed.
1255  Bitcoin / Bitcoin Technical Support / Re: Bitcoin wallet (Beta) - importing wallet Serious problem. on: June 24, 2023, 12:04:36 AM

I appreciate your response. Just to clarify, the legacy addresses in the Bitcoin wallet app are functioning correctly. I have verified this by cross-checking them with the results from the tool, and they match perfectly.

However, the issue arises with the segwit addresses (starting with "bc1q"). Unfortunately, these segwit addresses do not align between the Bitcoin wallet app and the tool. This becomes significant as the funds are currently held in these segwit addresses.

If there are any further insights or suggestions you can provide to help resolve this matter, I would greatly appreciate it.

Ok, So what you want to recover is the native segwit that starts with "bc1q".
Have you ever tried other ways to decrypt the backup file you can maybe able to decrypt it that only includes a private key?

Here's the method that I want you to try "[HOW-TO] Export Bitcoin private keys (in WIF) from Bitcoin Android (schildbach)"
This method only dumps private keys after decrypting the wallet backup from OpenSSL.
1256  Bitcoin / Bitcoin Technical Support / Re: Bitcoin wallet (Beta) - importing wallet Serious problem. on: June 23, 2023, 11:33:10 PM

I was able to get the correct seed ( 12 words) and I have tested using ian tool for BIP39 and it works and it shows the correct addresses for Legacy but not for the segwit (bc1q)

Have you checked the derivation path on the Iancoleman tool under "BIP32 Derivation Path" that's the correct derivation path that you need to use when importing the BIP39 seed into Electrum to get the correct legacy wallet.

Also, in derived addresses on the left side, it should show the path of your BTC address and what derivation path your BTC address belongs. Look at the image below as a reference



Or alternatively, export the private key since you said you get the correct wallet using iancoleman then export the private key from that tool and import it to Electrum. Make sure that you use this tool on an offline PC or else it's not safe anymore to reuse that wallet.






1257  Economy / Service Discussion / Re: Promotion methods. Dark & Bitcointalk? on: June 23, 2023, 04:31:06 PM
Don't compare the forum and the dark web because you can only access the dark web through the Tor browser while this forum can access in any browser another thing is if you are going to promote your exchange on the dark web it is not the same as this forum that can be index to any SERP(like Bing and Google) meaning only a few people can find your business because only limited people can access your exchange.

What's your purpose why did you like to promote the exchange on the dark web? Is it illegal?
The only reason that I think why you want to promote it on the dark web is because you don't want to involve in government policies.
1258  Other / Beginners & Help / Re: Neo and Atomic wallet : how can I move the neo or swap for btc ? on: June 22, 2023, 11:49:41 PM

I don't have step 3 "Select Neo Legacy and click Next"  Huh
If you can't find the legacy option it seems they already delisted it according to this link below you will need to export the private key and import to another wallet that still support NEO legacy.

- https://support.atomicwallet.io/article/343-how-do-i-export-my-neo-2-private-keys

I suggest try to import it to Neon wallet developed by City of Zion they have option there to migrate it to N3 once you've done to migrate you can send it to any exchange where you can trade it into BTC.

1259  Bitcoin / Mining support / Re: Looking for Antminer S19 90T firmware (or Antminer S20 firmware?) on: June 20, 2023, 11:44:57 PM
Did you ever find a fix for this, i just updated my s19 90T and the exact same thing has happened to me - tried all the firmwares, and sd cards and i am getting the same error

nand: WARNING: pl35x-nand: the ECC used on your system is too weak compared to the one required by the NAND chip Bad block table found at page 131008, version 0x01 Bad block table found at page 130944, version 0x01

if anyone found a fix to this i would appreciate it, thanks
It's just a warning but I don't think that's the cause of your issue would you mind posting the whole kernel logs here just don't forget to paste it inside the insert code tag just like the other post above because there might be other errors that cause this?

Anyway, I have a suggestion that you can try do you mind to try to boot Braiins OS to your unit? Sometimes other OS can bypass this issue.
1260  Bitcoin / Mining / Re: For how long on: June 20, 2023, 05:28:39 PM
No one knows when unless ASIC miner manufacturers announce a new miner unlike before they keep releasing new Bitcoin ASIC miners.

However, they are still manufacturing other ASIC miners for altcoin. If you want a tool that lists all new miners with release dates then check this tool below.

- https://www.asicminervalue.com/

Then sort them by clicking "release" to see new miners including the upcoming release of new miners.
