2001  Alternate cryptocurrencies / Altcoin Discussion / Re: XMR Zcash and other private coins are getting delisted from binance on: February 07, 2024, 08:15:02 AM
If you think about it, it was actually a positive move to temporarily block withdrawals. This kind of makes the market calm down a little, so that everything doesn't go into panic. In fact, it is a traditional strategy, which even occurs in the traditional stock market, to block negotiations on an asset, so that people do not act on impulse.
It's the exact opposite: by blocking withdrawals, the only option left is selling on that exchange. That leads to panic selling and a huge drop in price. The proper way to prevent panic trading is a trading halt. Ironically, that's the exact opposite of what Binance did. Makes you wonder....
2002  Bitcoin / Development & Technical Discussion / Re: Starting a Bitcoin Node using a VPS on: February 06, 2024, 06:53:45 PM
Has anybody tried to get or build a node from like Contabo?
I used to run a Bitcoin Core node on a dedicated server (until the disk configuration changed and I didn't have the disk space anymore). If I remember correctly, it uploaded about 20 GB per day. Far less than the 0.5 TB limit I set. That made me conclude there's no shortage of upload bandwidth in the Bitcoin network.
I'm still running the node, but pruned. That means it now only uploads the latest blocks to other nodes. I just checked: it's still uploading 3 times more than it's downloading.

Quote
I'm looking to try and really support BTC this way. What do you think are the benefits of this?
Based on the above: not much.

I've also installed a pruned Bitcoin Core on the cheapest pay-per-hour VPS I could find. With 16 GB RAM, it was quite fast. I wouldn't use that host for production, but it's great for testing.

I wouldn't use any default containers, just download Bitcoin Core and start it manually.

While your statement generally is true, it seems Contabo also offer storage-focused option. But with very low price, i would question the reliability and actual performance of such VPS.
A storage VPS, as the name suggests, is meant for storage. Although I've only used them with HDD in the past, in general, they're not meant to be used for load-intensive applications like Bitcoin Core.



As far as I know TryNinja's ninjastic.space still runs on a Contabo VPS.

Fees are back to normal but we can't have XMR for now:
Interesting. It looks like XMR first got dumped, and then bought back cheaper at eXch.
Since the price is based on other exchanges, that might be open to manipulation.

Update: It's not just that trading pair, I checked a few other pairs and directions, and it looks like all XMR trading was halted.

I just recovered from the panic mode and this post isn’t helping. Lol
Sorry, I'm not here to offer comfort Tongue

I don’t even hold too much money on there btw. I am panicking because I don’t want to get fucked over even if it is a few bucks.
So withdraw another coin, and exchange to Monero again. This time use an anonymous service. The value of your Monero on Binance dropped, but it also dropped wherever you'll buy it next. So other than trading fees, you shoulnd't lose much. And getting away from Binance is a big win!
2005  Alternate cryptocurrencies / Altcoin Discussion / Re: XMR Zcash and other private coins are getting delisted from binance on: February 06, 2024, 02:33:58 PM
This is theft no matter how you try to spin it.
And you're surprised? Wait until you read this topic!

According to binance, they disabled withdrawals temporarily.
That reminds me of this post:
The liquidity comes from users, and more people are buying than selling XMR. Maybe the fee trading in the opposite direction can be lowered to encourage adding liquidity.
This is the case even on big centralized exchanges, that is why they often don't allow people to withdraw xmr...they claim because of some maintenance, but they just don't have enough coins.
What if Binance was selling "fractional reserve Monero" and now gets a huge discount to cover it up?
2006  Economy / Exchanges / Re: eXch - instant exchange BTC / LN / XMR / LTC / ETH / ERC20 on: February 06, 2024, 12:32:19 PM
is there any kyc exchange that still list XMR? I think kraken does.
Correct.
Today's -18% means nothing compared on the 5 year price graph.
2007  Economy / Exchanges / Re: eXch - instant exchange BTC / LN / XMR / LTC / ETH / ERC20 on: February 06, 2024, 12:15:19 PM
I wonder why recently some pairs BTC-XMR for example charge 5% fees on eXch when just few months ago it was 0.5% fee ?
Probably because of this:
Code:
Reserves
XMR 0
BTC 88.43136183
That changed quickly:
Code:
Reserves
XMR 12339.699295434601
BTC 12.95379134
The 5% fee is back to 0.5 or 1% again. Probably because Binance delisting Monero. Monero dropped 17% now. Imagine that, people dumping their privacy coin because they can no longer trade it on a KYC exchange....
2008  Other / Meta / Re: Mixers to be banned on: February 06, 2024, 12:11:41 PM
The question is, will theymos ban privacy coins too if the regulatories take action against them? Now, that would be the end of the forum because that would mean banning legit crypto projects, it ain't the same as banning mixers.
Exchanges can't do their AML checks on privacy coins, Bitcointalk doesn't have to do AML checks.
2009  Alternate cryptocurrencies / Altcoin Discussion / Re: XMR Zcash and other private coins are getting delisted from binance on: February 06, 2024, 12:10:13 PM
That's a good thing, right? One doesn't just don't use KYC exchanges to buy privacy coins!
It's also a testimony to how well privacy coins work. Sure, Monero dropped 16% in dollar value over this, but that's just people speculating. Let me guess: they even kept their "privacy coin" on Binance's exchange? Lol.

Take note i DO NOT guarantee security of generated key using such marketplace.
Using "split key" can solve that problem: the server will never know your final private key, and you can even create the split key on an offline system.

I am 1 payment into the 100 payments I need to make up for the refund I gave to an un named mixer due to the mixer ban..  Just 99 weeks to go.
Why not try a different signature campaign on the forum you actually like posting? There's more than just mixers to choose from.
2013  Bitcoin / Development & Technical Discussion / Re: VanitySearch (Yet another address prefix finder) on: February 06, 2024, 10:07:53 AM
Does anybody have or had a GPU mining rig?
Talk to WhyFhy, he created (and ended) 1SPLiTKEY.com The easy, secure and mostly free vanity wallet service closed/down.

Quote
And I wonder if any of you with lots of hashing power had tried to generate a Vanity bitcoin address via VanitySearch? I'm talking about those who have at least tens of GPUs or in the best case, hundreds of them.
It's possible, but a very expensive way to create just a Bitcoin address.

Quote
I also wonder if any of you have tried to generate a Vanity address by using powerful AWS servers?
I've seen other pay-by-the-hour hosts that offer servers with GPU. I think it's more likely to be used to crack lost passwords than find a rare vanity address though.

Quote
Is it possible to direct hashrates rented on Nicehash to generate a vanity Bitcoin address?
I don't think ASIC miners can be used to find vanity addresses. They're build for only one specific task, and it would be too expensive to build a dedicated ASIC to find vanity addresses.

Quote
If you have tried none of them above, at least what's the longest Vanity address that you have generated?
See Rare address hall of fame.

2017  Bitcoin / Bitcoin Technical Support / Re: BCH, BSV in Casascius coins on: February 06, 2024, 08:37:13 AM
By "move your bitcoin" I guess you mean "sending the bitcoin to another wallet" ?
People have lost their Bitcoins in the past, when they installed a Forkcoin wallet that contained malware. Don't risk it, don't trust those wallets. Move your Bitcoin to safety first, then use a VM or other computer to install the Forkcoin wallet.

At current prices, for a 50 Bitcoin Casascius coin, you're looking at (give or take):
$2150000 BTC
$11700 BCH
$3500 BSV
$1500 eCash
$1000 BTG
$40 BCD
Some of those are only traded on exchanges I wouldn't easily trust. Don't send more at once than you're willing to lose. I can offer my services to recover those 5 Forkcoins, feel free to make me an offer.

Here's my take on offline signing:
Online:
Install Electrum on your PC.
Import your address to create a watch-only wallet.
Preview the transaction, Copy the unsigned transaction. Put it on a USB stick.

Offline and running without hard drive storage:
Get a Linux LIVE DVD. Use Knoppix or Tails for instance, or any other distribution that comes with Electrum pre-installed.
Unplug your internet cable. Close the curtains. Reboot your computer and start up from that DVD. Don't enter any wireless connection password. Keep it offline.
Start Electrum. Import your private key.
Copy your unsigned transaction from the USB stick, load it into Electrum.
CHECK the transaction in Electrum. Check the fees, check the amount, check all destination addresses (character by character).
If all is okay, sign the transaction. Copy it back to your USB stick.
Turn off the computer. That wipes the Live LINUX from memory and all traces are gone.

Online:
Use your normal online Electrum to (check again and) broadcast the transaction.
2018  Bitcoin / Bitcoin Technical Support / Re: Check BTC balance programmatically on: February 06, 2024, 08:19:09 AM
The best way to do would be to convert the actual Bitcoin UTXO database into a SQL database so you can search it.
This database is kept on every node but it is a LevelDB database that can only be accessed sequentially.
So you need a translation software to read it.
I made one myself in Java. It takes about 1 hour to convert the full UTXO to a MYSQL database. It's about 24GB large when only a few fields are saved (addresses, balance, block height, txid). It contains 162 million records as of today.
For OP's purpose, he doesn't need all UTXOs, only the balances. There are only 51 million addresses, so you could reduce the size of your database to 8 GB.

Quote
You can then do a quick search to see if a specific address is in the database.
If found you can easily calculate the balance by doing a select count(*).
Running the queries would need a pc with a very fast random access SSD and as much ram as you can spare (think 128 or 256GB).
How fast can you check a million addresses from this database?
2019  Bitcoin / Bitcoin Discussion / Re: Hypothetical ETF disaster hardfork on: February 04, 2024, 11:48:26 AM
I think that half of Bitcoin ETF users have no idea about hard forks and another half probably understands that they won't be able to claim forks.
They will realize it once it hits the media.

Quote
Doesn't the ETF of each coin need to be approved?
I don't think so. They won't create "Bitcoin Fork #2987 ETF", they'll just sell Bitcoin Fork #2987. The dividend infrastructure is pretty standard for brokers, so it shouldn't be too hard to deal with.

Quote
Approval of Bitcoin ETF doesn't mean that its forks like Bitcoin Cash, Bitcoin SV, BitCore, Bitcoin Gold, and others are automatically approved as ETF.
I'm not talking about past forks, I'm talking about future forks. Past forks are irrelevant.

Quote
I think that no one has thought about how the claiming of forked coins would work in the crypto ETF world.
I'm pretty sure someone has thought about it, and decided keeping the money is the easiest solution.
2020  Bitcoin / Bitcoin Discussion / Re: Hypothetical ETF disaster hardfork on: February 04, 2024, 10:01:58 AM
When there was a Bitcoin hard fork in 2017 and BCH was created, I remember that many casinos, exchanges and other companies were suggesting people to withdraw bitcoins during the fork because they weren't supporting the fork.
That works, as long as users are dealing with Bitcoin. Now imagine an ETF holding a million Bitcoins in the future: "withdrawing" all Bitcoins means selling them. The Bitcoin market will crash hard, and boom again when they buy back after the Fork.

Quote
Then, after some months or probably after a year, everyone did it differently, they donated people with Bitcoin Cash that was equal to their balance.
I think it isn't and shouldn't be their responsibility to take care of every fork and they won't do that because then they will have to approve the ETF of that fork, just my two cents.
I guess we're going to disagree on this. A Fork is like dividend: any other ETF takes care of the dividend for it's users, and in exchange they charge their users a "fund fee".
Here, different (stock) brokers advertise with "dividend leakage": depending on how they deal with taxes, you may or may not be able to get back the paid dividend tax. That's a difference of about 0.1-0.2% per year, and it makes a huge difference in the long run.
It's probably a matter of time for Bitcoin ETF brokers to offer something similar: if one Bitcoin ETF keeps any "Fork dividend" for themselves, and a competing ETF gives it to customers, the latter will be more attractive to the informed investor.
