701  Economy / Economics / Re: Electricity bills worth 500,000 euros: a hotel chain closes down in Italy. on: October 03, 2022, 03:14:56 PM
Looks like electricity prices have tripled in Italy too so that would have taken a bill that was probably around €160K and made it the €500k.

Considering most of the EU was meant to be half renewable and is on paper, I don't know why these rates are going up so much and why larger companies can't take advantage of it and make renewable sources a lot cheaper. At this current rate, the whole of Europe's economy might end up hibernating or moving in order to sustain production costs (put uprooting whole manufacturing plants and transporting them to countries like Canada would be expensive to do quickly).
702  Economy / Trading Discussion / Re: DONT GIVE ME FISH on: October 03, 2022, 03:04:14 PM
I'd recommend getting used to paper trading and spot before going in with leverage. It's damaged a lot of portfolios - most of the time because people don't know how to manage risks.

Leverage essentially lends you money given your provided collateral and allows you to trade with more. If you put down $1000 and wanted 20x leverage, the exchange would lend you the other $19000 and you'd be able to trade with that. The catch is you'd then get all your funds wiped if the asset drops by about 5% (or a twentieth in price). You also have to pay a funding rate every 8 hours (with most exchanges) to cover the interest of the "loan".

There's no way an account can go negative but a good chance it can go to 1% if you're not doing diligence on risk management and don't incorporate it into a strategy (such as limiting trades to 1-5% of total funds in the futures account and then customising that based off success rate).
703  Bitcoin / Bitcoin Discussion / Re: Gary Gensler's SEC sues Crypto Influncers and posts on his Twitter as propaganda on: October 03, 2022, 02:58:07 PM
I think most people are aware by now they can't advertise for something and receive payments without disclosing that you are being paid for it/have an agreement. This looks like that. This might be more of a twitter problem with there being a limit to the number or characters they can use but they also didn't try to hide the reason.

Pumps and dumps are illegal too, there's a chance the sec going after unknown coins being advertised attracts people to bitcoin:
1. Because it makes it look like the sector is being regulated
2. The sec has had a fairly neutral position on bitcoin imo (it might come across as negative because the point in regulatory bodies is to find problems and things to target - bitcoin was once rife with lots of scams and may still be).
704  Economy / Economics / Re: 100 years ago, Henry Ford wanted an alternative currency. Well before Satoshi on: October 03, 2022, 01:53:32 PM
He probably had high goals for making things more efficient (or competing with others to do it) and creating a monopoly out of the new currency though or maybe he already had some hold on oil fields/production.

The US Dollar did, in a way, base itself off oil (and it also then ended up being used for war funding and fuelling).

I prefer that this sort of thing is being done now when there are many different ways to generate power at similar costs from different sources and there aren't just a few people with monopolies on systems (I wonder if bitcoin would've forced the Internet/phone lines to be developed faster though - but then there's still some areas with big populations that only have 3g or 2g so possibly not).
705  Bitcoin / Bitcoin Discussion / Re: Can bitcoin be used to clean environment and reduce waste?? on: October 03, 2022, 01:36:49 PM
The energy companies are against carbon neutrality and fixing the problems they caused.

The issue with biofuel I can think of is it still produces waste gasses (but does reduce overall waste and might redirect some but landfill is normally compacted well to do that too - the waste normally isn't allowed to breathe for long).

I was looking into using renewables for crypto mining and it looks like they might pay higher than directly connecting them to the grid (for smaller sized operations) as the power companies normally only offer half the price of the electricity in return while it's generated (although that was taken from solar and I was looking into wind). That being said, at $400-2k a miner and $3-6k a wind turbine to power it there's probably a reason there aren't that many people doing it.
706  Bitcoin / Bitcoin Technical Support / Re: How to detect 'change' transactions on: October 03, 2022, 01:06:01 PM
I can't remember the name of the site fully but I think it was wallet explorer that tried joining addresses together for spv clients: https://www.walletexplorer.com

I think there might be ways this has been done with other places but blockchain.com removed there's because it seemed to get quite a lot of things wrong.

One way of seeing if an address was change would be to analyse what the wallet has done before or to pick and output you don't think is change (such as one that's not spent instantly if the person was paying an exchange/service/payment processor).
707  Other / Beginners & Help / Re: what is the difference between nodes and miners? on: October 02, 2022, 05:49:56 PM
Thanks... Very much for the explanation. i am little confused cause its hard to understand. can you explain by simple words

In what ways? Is there something you're more familiar with I could use?

Whenever someone wants to spend bitcoin they must generate a transaction and share it with nodes (most miners then collect information from nodes to mine them and confirm the transaction).

Hashing is performed on the transaction to get a txid (which you might be familiar with). A hash is a form of compression algorithm - you could imagine it like a remainder function if you don't want to go on a deep dive through the workings of the algorithm (sha256).

Once this transaction is made it must be shared with others, these others are nodes that act as the backbone of the network as they facilitate data sharing.

Miners then collect these transactions together in "blocks" and form merkle trees. The root of this tree with other information like a timestamp is then hashed to make the blockhash which is then tested to see if it's below a certain number. (finding a diagram of a merkle root tree or an explanation is likely better than me explaining it).

The mining target is hard to work out because of the way the algorithm works. If you needed to find a number close to 2 and the function was 256667 % 59 (where % is the remainder function, 59 is a coefficient and 256667 as a number set by the algorithm - this might be a bad example as a remainder function is still fairly linear but it's easier to explain than sha256). Most of this is done by ASICs (algorithm specific integrated circuits) as sha256 is an algorithm that can be programmed onto a chip.

Once these blocks are found they're sent to a node where they're then distributed to other nodes. All nodes need to share with each other is their current block height and the hash of the last block to see if there's anything new they need to listen out for.

There are other messages nodes send to others such as a list of peers they're connected to so the other node is able to connect to them.

Nodes have their own consensus rules too that can be modified by whoever is running them (or the node itself algorithmically - this is done for things like mining difficulty which is set as an average of the hashrate over the past 2 weeks worth of blocks: every 2016 blocks).

Blocks are targeted to be found at an average interval of 10 minutes but it works as an average as sometimes it can take over an hour for a block to be found and at other times two blocks can be found fairly close together. As the nature of how a block is found is random (meaning it's hard to predict when it will be found) and spontaneous (meaning it can't be predicted who finds it) there are no advantages for doing things like finding empty blocks vs full blocks (except full blocks have higher rewards due to incorporating transactions and taking their fees).

Transaction fees and block rewards are both paid to the miners of a block. Pools function as a large collection of miners and share their reward when they find one (the pool operator also takes a fee from this though).
708  Bitcoin / Bitcoin Technical Support / Re: how sensitive is wallet.dat on: October 02, 2022, 04:37:51 PM
It depends on whether the alphanumeric code is truly random or not. As long as you have 16 characters that are random then you should be fine for now..

If you happen to have words in there then the password might become solvable for an attacker.
709  Other / Beginners & Help / Re: what is the difference between nodes and miners? on: October 02, 2022, 04:32:16 PM
Miners = find blocks and claim block rewards by repeatedly changing variables within the block until it's hash is below the target nonce set by the network.

Nodes = accept blocks, impose consensus rules individually and propagate (share) transactions that haven't yet been confirmed and blocks that other nodes don't yet have (they also share these transactions with miners and share the identities of other nodes to support other nodes' connectivity).
710  Bitcoin / Bitcoin Discussion / Re: A New Study - Bitcoin is 56x more energy Efficient than Traditional Banks on: October 02, 2022, 04:24:13 PM
"We demonstrate Bitcoin consumes 56X less energy than the classical system. When Lightning is compared to Instant Payments, Bitcoin gains exponentially in scalability & efficiency, proving to be up to a million times more energy efficient per transaction."

Source of article is needed in OP.

I found it! https://twitter.com/lopp/status/1537440210203553792

(there's others but I don't have seen that name before so I'll share there's).



I've found research papers that point at its efficiency being higher and I wouldn't doubt that either. Especially if bitcoin's inflation drops and the price stabilises. Computers consume power even if they're idle, if these are used in companies to handle the burden of lighting payments then they'll still consume about the same amount of energy and will be contributing to the network for free (same goes for normal computers that are lighting enabled).
711  Economy / Trading Discussion / Re: When Will Bull Run Come Next Time? on: October 02, 2022, 04:13:33 PM
Bull runs normally happen when bitcij makes the news. The halving is normally something that does this and attract new investors to it (and it seems to become quite a big event each time it happens - price and volatility wise). I'd guess the stability in price of a bear market also confirms to new investors that there's a comfortable floor to the price too.

You've made 6 posts and two of them are in the bounties section, that's probably why you're thinking it's hard to get merits (it's hard to give them for a lot of members as they have only a few smerit - it's easier to get them and easier to give once people have made more posts and are more likely to linger/write on the forum for longer).
712  Bitcoin / Bitcoin Discussion / Re: Net Bitcoin ATMs growth drops globally for the first time ever on: October 02, 2022, 09:43:14 AM
They're likely costly to uninstall (including the costs of the machine as it goes from being active to not).

I wonder what's happening with those 800 atms once they get disconnected, they're probably only useful as bitcoin atms so they'll probably come back online elsewhere or maybe at a different time. There was news a large currency exchanger with 3000-4000 machines (from memory) started accepting bitcoin, what if they've taken a lot of the demand here too from other places as machines that might have cheaper rates if they serve other functions too.

Perhaps if the companies hosting them have worked out they make a lot more money out of bull markets or more money out of announcing they have crypto atms they'll probably be turned back on in a few years when the next halving is.

713  Economy / Economics / Re: CEO to Worker Gap is 351-1 Ratio in USA in 2022 on: October 01, 2022, 08:13:54 PM
I think this implies people below the ceo are doing too much work. If that stops it'll probably go back to what the average is elsewhere. Perhaps there's also a chance that things like referral/franchise schemes coupled with automation has meant there are fewer people needed to manage everything but this is a quirk specific to countries like the US that are more likely to have companies that serve the world and weak unions because they can hire internationally. It could also be an issue with anti monopoly laws not working the way they do in other countries too - which I think is a big one for the US. If Microsoft, Google and Amazon were founded in the UK, they'd have been split into a lot of smaller subsidieries and I think the US stock market would probably be more stable from that.

I think the data gets exaggerated a bit by focusing on specific CEOs so it's very hard to compare how this works out internationally (average ceo salary in the US looks to be 10x the UK's for example but I'm not confident on either of those figures as the US was quoted at $800k which doesn't match your 165:1).
714  Alternate cryptocurrencies / Service Discussion (Altcoins) / Re: Play to earn projects can be regulated too? on: October 01, 2022, 05:13:35 PM
Most defi platforms use centralised structures to deliver their platforms (like traditional Web hosting and dns over having peer to peer hosting mechanisms). A lot of the NFTs can be sold in a decentralised way once they're created on those platforms but if the devs decide to change smart contracts there's little you can do about it (aside from selling the tokens and coins).

There are probably ways to actually avoid this and work directly with the smart contracts but they're probably not as fun graphics wise.
715  Bitcoin / Development & Technical Discussion / Re: can't close libbitcoin_node_a-net_processing.o: No space left on device on: October 01, 2022, 05:05:25 PM
Have you tried doing that bit from a fresh reboot when less is running on the device. Also I remember there are flags with compilers that let you limit how much space they use and how aggressive their garbage handlers are, have you tried looking into that to see if you can limit it to the 4gb elsewhere (I thought it'd do it more automatically though - the error isn't too descriptive of where it got stuck either imo).
716  Other / Off-topic / Re: Your information Diet on: October 01, 2022, 11:54:22 AM
This is quite an interesting way to put it because a balanced information diet in this case is going to remain the best, but different from life you can just have small amounts of a variety of information in order to get the full picture on what's going out there - in the end I think most people with accurate data get it from factual news outlets (like Reuters or similar media sources that have a relatively low bias or take informed decisions from statistics).

Even on financial markets a lot of companies get things wrong. Take the companies proclaiming twitter became privately owned by someone because they had an agreement only to remain listed on the stock market and tradeable. A lot of news tries to be the first to report on something and a lot of those outlets get a lot of things wrong because of it.
717  Bitcoin / Hardware wallets / Re: Trezor hardware wallets can be used without creating a seed on: October 01, 2022, 11:36:11 AM
Looks like it's the nmemonic (seed) backup you can skip and not the seed creation part?

I skipped backing up my phrase for a while as I was just playing with the wallet to start with. I think it's likely that option is in place because they might've had bad ways of backing up your wallet and it was safer to skip the backup steps after you copied down all of the nmemonic (to skip any verification steps of there were any that weren't just on the device).
718  Other / Beginners & Help / Re: One way to avoid scam wallets on: October 01, 2022, 04:11:57 AM
There are other handy places that may help you find a good wallet too, there'll be other well trusted examples but on i can think of is bitcoin.org: https://bitcoin.org/en/choose-your-wallet

They give you a quiz of what's important to you and then suggest the most appropriate wallets to match.

[the only scams I've seen from the wallets they suggest have been ones where people have clicked links inside wallets - one of the advertisers on mycelium and the phishing attack on electrum and that's probably a good thing to keep in mind if you're using a wallet too). All boxes that try to get you to click a link that opens a browser should be searchable (either by an error code or the popup box name).
719  Economy / Gambling discussion / Re: Woman Abandons 4-year-old Child In Gambling Shop As Collateral After Huge Losses on: September 30, 2022, 06:00:09 PM
Also, i'm surprised that the gambling shop accepted the woman's deal in the first place as I think it could've been avoided if they didn't take the collateral but maybe the guys from the gambling shop are desperate to make money.

It could've ended badly for them too so I'm surprised they would seriously accept such a "trade". Or maybe they wanted to take the child away from the mother or get her to get help by taking them away and getting her to collect them from a police station.


This is the height of it, making the innocent child suffer for her own irresponsibility. The child should be taking into government care and such a mother if found should be arrested and taking to rehabilitation. I wonder what her intention was, maybe that the child should be held by the gambling shop to repay the equivalent of the money lost in labor.

I doubt a 4 year old is going to be very productive working in a gambling shop. They probably did the right thing handing them over to the police (as long as they can have a positive effect from there).
720  Bitcoin / Bitcoin Discussion / Re: Spain’s Largest Telecom Company Telefónica Now Accepts Bitcoin, Crypto Payments on: September 30, 2022, 05:50:13 PM
Looks like a similar form of acceptance to steam, let's hope it lasts longer Sad (I do still miss it as a form of payment there).

It's good that companies are accepting bitcoin but a bit shameful they're mostly doing it through the same provider (though it might just take time for banks to get on board with accepting and converting it themselves).
