Did you manage to work out how much the markup was? I feel that anything around 2.5-10% might be considered reasonable, especially if they'll hold the rate for a few hours.

It's 8% at the local ATMs
There are some that are farther away that were less, but for a test to throw $50 in a machine it was not worth the gas & time.

They give you a choice of 2 fees fast or slow that YOU pay.
There is no medium option or showing of fees just the USD amount. Slow was the 5 sat/b but did not know that till I looked at the TX after the fact. All I saw was the USD amount.

It's a 2 hour hold on the BTC / amount and not 1 second more.
There is no cancel option. Just start another buy.
AND
You have to go to the ATM you picked out from the app.
That screwed me up as I had to go to a customer in the other direction the 1st time I tried so I went to a different ATM.

So I tried it and bought some BTC (all you can do where I am) expensive, but not horrible.
They overpaid on the network fee but that could just be a customer service thing. Even if the blocks are empty if you send at 5 sat/b you know that it will be in the next block.

Process was start buy on app, get price that is fixed for a couple of hours, go to machine, put in cash, get BTC.

Question is, if I am in an area that allows buy & sell can I sell, or does it go by where you live?
Will have to check it out when I am in a different area.

4083  Bitcoin / Bitcoin Discussion / Re: Hey! Let me pick up a rock and let's buy it from each other... on: August 09, 2021, 11:08:10 AM
I guess the question really comes down to what CAN'T you buy with BTC.
Through places like Bitrefill / BitPay you can get gift cards for just about anyplace.
Through Coinbase / BitPay you can get a debit card that can be funded with BTC and other cryptos.

There are 1000s of online stores that take BTC through various services.
And so on.

For anyone to say "We can hardly buy anything with it." means they don't have a clue.
There are even stories of people out there who lived on crypto for a year. Yes it was a stunt, but it can be done.

Bit of a necro bump here, but I was looking for another post and saw this one.
Checked the https://foundationdevices.com/ site and saw that they are shipping.
BUT they say ship in 7 - 10 days from order, so they might be 3D printing the cases as needed.

Anybody out there order one? As I said a few post up at $299 I am way to cheap to get one.

FWIW my friend running a BSV node to try to get some real facts about these reorgs had several gaps in his monitoring coverage when the BSV node software attempted to use more than 40 GB of ram as part of a reorg...  Probably some of the issues they had with these reorgs were due to miners crashing due to running out of memory while attempting to reorg.

And this was without any spamming beyond the baseline spam performed by Ayre and his companies to try to fake there being interest and usage of BSV.


Interesting makes you wonder if you do another long reorg with empty blocks and then a few mega sized ones at the end what would the chain do. Epically if then they have to go back and re-download all the 'legit blocks' how many times would that have to happen before people stop trading it.

OR

Bloat their mempool, release the fork with no transactions that starts a few blocks before you added the bloat, then release the bloat you created before on their chain. So the nodes start to stall due to your bloat, then they invalidate your block and they stall again trying to get back on their chain.

As I said before this has always been in the back of my head with the few crap alts I play with. There is no money in them so if someone really does something it's a shrug and walk away. No real money or time lost. But, lets face it, how many people really want to bother forking and destroying 'Dave's itchy left testicle coin'  [ And the thought of my itchy left testicle is going to live in your brain now  Grin ]

I wonder if anyone has tried spamming this shitcoin's network with transactions that take too long to verify. Although I haven't checked BSV's code to see how much standard rules they enforce to prevent it, I know it inherits a lot from bitcoin (since it is a copy); for example the SHA256 exploit can't be used since by default BSV uses BIP143 (Transaction Signature Verification for Version 0 Witness Program) sighash algorithm for all signatures.

If someone plan to do it, i would suggest them to look for any operator, cryptography or feature which not exist on Bitcoin. I expect it's less tested or audited.

Or if they are using something that DOES exist on BTC, but they are using an older version, with bugs, that they have not updated.

I bought some ADATA NVMe SSD and I returned it on the following day. It was overheating despite using the included metal heat spreader.

Because good thermal paste / pads cost money and ADATA is cheap.
Sorry to say it but back in the day, over 5+ years ago, they were a good quality low end drive. Now they are just crap. Don't know if it's just greed or if something else changed.

And after a 3.3% and 2.5% drop LTC just had a 9% difficulty increase.
BTC is looking like a 6% gain about 60% way through the 2016 blocks.
So it looks like miners are slowly coming back on.

Wonder how much gear is now in transport around the world.

For the BTCPay server for convert to fiat payment forwarding though Blockonomics has been discontinued. Not sure when they shut it down.

Also, although a 500GB drive will still work, if you have your OS on it, it will be out of space by the end of the year at this point if you are running a full node and lightning node on it.

I am already vaccinated, however, if I had to get the covid vaccine through BSV, I would likely become an anti-vaxxer, flat earther.

No THAT is possibly the best sentiment ever about BSV. Will you be believing the stuff on Ancient Aliens too?

According to the article you cited, the 1000 limit of chained unconfirmed transactions is to allow things such as games to be played on the BSV blockchain. While interesting, I don't think there is a benefit to having every move every player makes in a game permanently recorded on a blockchain. As I noted, the miners should be able to quickly confirm many chains of 1000 unconfirmed transactions or any other spam attack on the BSV network.

Difficulty dealing with spam attacks is not limited to BSV or even altcoins. Bitcoin nodes run by 'normal' users had difficulty dealing with previous spam attacks against bitcoin. Even some of the major businesses had difficulty dealing with previous spam attacks.

Eliminating the cult of personality surrounding Faketoshi, and it's lack of hashrate, and the lack of refinements in it's code. The lack of a blocksize cap on BSV and it's vulnerability to spam attacks makes it more vulnerable to spam. Once again from people who want to screw with it. I play with a few alts. All of which can be forked and blown out of existence for probably less then $500 at nicehash. Their marketcap would plummet from $10 all the way to $0.50 oh no, not that.

Now the mining attacks on BSV probably cost a fair amount of money. BUT there was no corresponding spam attack. Picture the damage that would be done if really did the following.

1) Mine (legit) a few hundred coins
2) Move coins to 1 address.
3) Start building your fork chain
4) Move coins to largest BSV exchange
5) Begin spamming the BSV chain and keep it up
6) Sell your coins
7) Release your fork chain without your move to the exchange or any TXs for that matter
Now above EXCEPT for #5 this is a classic double spend attack
Cool Keep spamming the BSV chain

Now in addition to having to roll back the chain you can in essence make the nodes have to deal with 100s of massive blocks filled with crap.

I can see 2 things happening.

1) The largest BSV exchange takes a hit, will they stick around or drop the coin. Might be worth it to do to #s 2 & 3 instead of #1 since they might not be as friendly about it.

2) Watch all the BSV nodes scream in pain as 100's of GB of data has to be dealt with. With many of them dropping off since the time they took to deal with the non spam filled re-org was very long. Which was what caused a few of the other issues they had.

Now, once again, this is a massive waste of resources and since you are essentially stealing from the exchange it's probably illegal too. BUT it would probably get BSV out of our collective hair.

At this point I think we should be discussing this on a different thread since it's just about BSV and not BTC.

OK, I have to ask who is mining this and where?
Difficulty is over 100 there are no pools that I can see and the only exchange that supports it has no trades.

So unless there is a pool that I don't know about and an exchange it's a hell of an expense at the moment to mine this since your scrypt miners can be making you a fair amount of money just mining LTC.

4091  Bitcoin / Bitcoin Technical Support / Re: Best Hard Drive for Bitcoin Node? on: August 06, 2021, 11:24:32 AM
What type of hard drive do you suggest for running full Bitcoin node, older technology HDD with big capacity or new technology SSD drives?

It seems that my 4TB HDD (not my main drive) may be dying soon as it started to disconnect and connect at random times, but health status is still good and I can't find any bad sectors or the source of problem except one software detecting there is one Uncorrectable ECC error.

My main SSD is used for operating system and software I use regulary, but I guess running a node have some effect on longevity of drives and I think they make them with lower warranty (mine expired) on purpose.

So my question: Is it better to buy new HDD with larger capacity or SSD with 1 or 2 TB, and what drives are you using for running your Bitcoin nodes?

Check your cables & connectors on the drive. Disconnections / reconnections are not the way drives usually die.
Obviously, things happen and yours might be dying that way but after 25+ years doing field IT work I have not seen it happen more then once or twice.
Edit: ETFbitcoin beat me to saying the above but if possible don't just swap cables if you have a spare port on the MB try that one too.


If it was me I would split the difference and go with a 2TB Samsung SSD.
Well under $300 US I don't know where you live in the world or your financial situation, but they are all I have been using.

It's quite interesting that despite everything BSV's price is still holding up and pretty much in lockstep with the rest of the market. Pretty telling really about how little fundamentals matter when it comes to altcoins.

For a lot of them yes. This one is a special case, people who use it / believe in it really drunk the cool aid so to speak IMO.

Or the coins used to taint all address and strees the network.

Ohhhh, I like it. Make a pool, mine a few blocks, send more then dust to 1000's and 1000's of addresses, then start forking the chain. Wait for them to revert the chain again and block all coins that come from that address. Forcing everyone to use some form of coin control.

I guess they could also just target exchanges one by one and dump the fresh coins into one then another and swap for other alts. If you pull the coins out and they revert then the exchanges loose money. Sooner or later the exchanges will stop allowing deposits. The down side is they may bring forward more legal headaches then it's worth.

...
In 2015, it was around 40GB. It is now over 300GB. My computer has a hard drive with 500GB. While I would've been happy to download the block in 2015, it is now too big for me. Yes, I could easily fork out another $100 to buy a new hard drive but this is something I wouldn't have needed a few years ago.
...

Except in 2015 low end / middle spec PCs were coming with 256GB drives. So although it was a smaller percentage of it, it was still a large percentage.

You really seem to be running around this forum looking for ways to prove BTC is not viable. No idea why.

If you don't like it, don't use it.

And for certain if he plans on buying gear not renting hash power, he will not buy brand new gear for that, it doesn't make sense at  all, you simply want as much hashrate as cheaply as possible, why spend 100$/th when you can get it for 10$ with old gear that is sold at scrap metal price. The difference in electricity consumption will not matter since you're only running this for a day, not to ROI. Besides, 5c/kWh, that's closer to consumer prices in some countries than industrial averages.
...

Yes but with 2 or 3 generation old gear, your power NEEDS go up.
In terms of doing something like this, unless you are a major company, a government, or really rich, it's already going to be somewhat difficult to get a facility that has the power & cooling. Adding the need for more power & cooling is just going to make it more difficult.

With that being said, any of the big farms that were in transit, that have found new homes, doing this as a test before going live would be no big deal at all. BTC would not notice if 1/2 of 1% of it's hasrate came back online a few days later.

Quote from: PrimeNumber7

The real money to be made from 51% attacks comes from the potential for double-spends, and from the financial markets. Someone who is preparing to execute a 51% attack could sell the ability to double-spend specific transactions ahead of time. They could also place bearish bets against a coin they are about to 51% attack before they start the attack with the advance knowledge the price will likely fall.

Quote from: PrimeNumber7
You have to factor in the block rewards you would receive if you were 51%'ing BSV, which is around $135k/day.


If you are doing something like this you probably don't want any money trail looping back to you or your operation.
Just make that chain / coin useless until it goes away. If you have the money to do this and if my $450,000 number was accurate getting $135,000 back which although a non insignificant amount of money might not be worth it based on the risk / reward. Faketoshi loves his lawsuits. If the coins go nowhere, you can't trace who to sue. Although, it would be funny as hell if they just kept moving, splitting and combining them to make them waste time chasing them.

I'm pretty sure it bumped down an equally bad project.

4096  Bitcoin / Development & Technical Discussion / Re: 51% Attack on: August 04, 2021, 08:34:07 PM
....
Someone said that numbers from that website are outdated and that may be true so I would like to see correct numbers, but I was really just looking to find how much attackers paid to take over Faketoshi's coin.
I not worried so much about someone doing Bitcoin 51% attack when there are much cheaper way to attack it with fud, regulations and mainstream media.

Well if we use those numbers or close to those numbers or close to them the BSV hardware = $19,0000,000 x .05 (percentage of the BTC network vs BSV) = $950,000 power = $13,000,000 x  .05 = $650,000 a day


On the other hand, if you look at what is available at nicehash and mining rig rentals you can do it without even buying a thing.

The most expensive bid I can find at the moment is 0.0133 BTC/PH/day lets use 0.015 because it's an easy number.
BSV hashrate is .44 EH/s lets use .5 to make a nice buffer and better math. so 0.015 * 500 = 7.5 BTC a day or about $300,000 a day.

So for someone with money, not much at all.

Yes these are all theoretical numbers, since once you grab that much mining from nicehash / mrr the price will go up. But I figured 10%+ over on hashrate and 10%+ over on price. Even if you wanted to go 50% over you are still only at $450,000 a day.

Anybody want to chip in for a test?

It has been discussed on other forums that part of the issue is forums like this themselves.

If I search for how to do something with my car, instead of winding up on a forum, I get links to other sites. Blogs, youtube, medium posts. Almost like G is penalizing forums.
And lets face it, that might be a people problem, they are thinking don't TELL me how to reset the oil warning light, give me a 1 minute video.

Since G does give links that have been clicked more times more weight in a search (or at least they did) it's kind of a self fulfilling prophecy. Nobody clicks on the 10 step how to, so it gets buried, then you can't even find it. Just the videos on how to do it.

If more people search for something about BTC and wind up clicking on github, or medium, or wherever then links here become harder to find.

No impact at all, no "inflation bug" coins were created.

2) Is this still a threat to the network at the moment?

No.

3) I don't mean to be attack Bitcoin, but how is it that a bug as critical as this was discovered 10 years after launch, especially with so many developers working on the project (and bitcoin team being considered a conservative bunch that values security)?

Programming errors are out there now and will always be out there. How they are handled when found is more important then the fact that they exist.

It's probably worth reaching out to CMC and see what they say.

But, remember Mycelium sat down and coded 1x into their product, so you know there was some communication between the two of them.
