Thanks for your good wishes, I had no idea the SigCamps were so lucrative (inspite my years of scam busting) until I started looking at a couple of shit posters who are in the campaign you're currently in.

Yeah I'm not great at checking others' quality, although I guess a lot of shit posters just use similar patterns anyway...
Sigs are pretty good if you're going to be here anyway, I've seen a lot of people saying they're a problem, and they did used to be a massive one, but they're also good if taken up by genuine members that can help to bring on more interesting discussions - its also how this forum will actually do better in things like Web rankings since it also stops bct becoming a wasteland of randoms (icq didn't look to be very busy in comparison but I wasn't there for long)...


I did have a look for 777 etc LN Nodes and couldn't find any.  I'm just running the one Zap wallet for the time being.

It wouldn't surprise me if they're waiting for a bit more on the developmental side before offering the lightning network. We're still in the in development phase round here imo... Software will always have bugs but the lightning network hasn't had some more supporting forms to it yet and is still fairly primitive while still functioning with enough security as is needed for now...

Welcome back - Casinos still seem to be the short term future for the LN on this forum: https://bitcointalk.org/index.php?topic=5241733.msg54255122#msg54255122 How can we turn this into a long term solution?

Thanks! Welcome to my old sig camp too (I was there until sr when I left due to changes and joined bitmixer)....

We have a lot of gambling sites already in the ln. It'd probably be one of the first places where the adoption occurs and its nice because there are less traces on the ln - if you want to be a bit more anonymous with your gambling then it's nice (although 777 and others probably do something similar already to anonymise their addresses).

Gambling sites also seemed faster than exchanges to switch over to native segwit acceptance.
4363  Economy / Lending / Re: Free lightning tests on: April 19, 2020, 12:59:24 PM
I'm back again, available for 12 hours today if anyone wants to submit a request or wants to discuss the ln (if anyone needs info on how to do it).

We sent inquiries.  We received emails thanking us but not hiring at the moment.

I think your government lies my friend. I saw Boris Johnson was in the ICU... that was the most laughable propaganda I've seen out of all this shit!

More hospital layoffs are ramping up across our country.  The hospitals are still ghost towns.  It seems management is starting to make the doctors work again... the doctors are all cheering for the government to "subsidize this war"... it's almost laughable at this point.  S-c-a-m-m-e-r-s.

Yeah I think management in every country is bad at the moment... Not sure why they're still putting out adverts if jobs have already been filled (probably making those at the front in icus feel better)... I know a lot of staff are off though so all this is very concerning (it'll be at least an eighth to a quarter)....

And yeah Boris going into intensive care was rediculous too... Propaganda still remains one of the governments main strategies, nothings changed in the 110 years since the start of propaganda campaigns...

Did you get anywhere with this? There are still lots of ads from the government trying to aggressively hire as many nurses as possible...

I think they're after enlisting at least ~16000 from what I can tell

Bitocin is generally considered a speculative commodity, most stocks aren't.

When investing in stocks, you're investing in the dividends they can return you and you can see the profits the company makes and a lot of information on them.

With bitcoin it's quite a lot different, you can't say if we do better for profits than last year - you can just look at the price... But both have big problems... If the profit on a company turns negative, they can quickly collapse and become bankrupt - if bitcoin is made illegal, you might have to quickly rush to sell your stake...
4369  Bitcoin / Bitcoin Discussion / Re: If we are to start from beginning. on: April 18, 2020, 08:49:44 PM
I would like the supply of bitcoin to be higher then the finite 21million. I believe, this BS is very limited for the whole world and will be highly scarce.

I would rather bitcoin keep growing at a stable .5% or something actually to maintain its uses. A lot of those 21 million coins may already be lost, and if enough keep being lost then we're going to really stuggle to sell a coin with one or two main bulls and a load of people below them...



I'd personally like to see less greed and an impact noticeability for people's actions, a lot of people not at the top aren't at the top because they can't handle their own funds an da lot of people near the top may have far too much influence over certain things people need...
4370  Bitcoin / Bitcoin Discussion / Re: 5G & Bitcoin Risks? on: April 18, 2020, 08:23:21 PM


I hear 5G towers are less power consumption in compared to 4G however the new 5G frequencies are super high and fast but shortwave by nature meaning the signal is powerful but cant travel far.

Dont know what kind of cpu's in the 5G towers. Can these cpu's or frequencies decrypt encrypted data real time or impossible?

If there's a simple backdoor in common cryptographic operations then they may be able to decrypt your data.
If you've connected to a website and haven't got a secure connection failed error, it's unlikely they've been able to decrypt your packets. I don't know if additional encryption would be added at these nodes but I'd say it'd be a foolish inefficiency...
4371  Other / Beginners & Help / Re: All of my bitcoin questions gathered. I need some help here... on: April 18, 2020, 08:10:45 PM
1) Okay so the first question I have is about blocks. If you go here: https://blockchair.com/bitcoin you will see a transaction live count. It gets increased and decreased as well. Why it does? Are miners involved in this?
Transaction number hasn't yet changed for me but I assume when a block is found, they may find the average and add it on or it may decrease when a block becomes orphaned.

2) Why block generation time is always standard? Every day 144 blocks are created (since 210240 every 4 years, I did the maths). Why? I've never seen such question anywhere. I think on our wiki it says new block every 10 minutes.
The blocktime adjusts every 2 weeks (2016 blocks) to amek the time for a block to be found 10 minutes. This is all based on the computation power dedicated to the chain over the past 2 weeks.

Block discovery is a bit like radioactivity, we know the average will be around 144 a day but there won't always be 144 a day there might be less, block discovery can be anywhere from around a second before to 2 hours after.

3) Mining is the main source of questions. To start with, miners want to mine for 2 reasons. For guessing the hash of a block meaning that they will earn 12.5BTC and for earning bitcoins from transactions fees.
Yes? Is this a question or just a statement? They get both of these - fees are just an additive difference between transactions so a standard block may see 100.1BTC move and 100BTC be assigned, the other 0.1BTC gets added to the block reward.

After a lot of research I have understood that each block's hash has to do with the previous block and some other things (like SHA256(some stuff in here including the prevBlockHash)). What exactly are we trying to guess? And even we if we guess that "thing" correctly, who promises me that it will write to the blockchain that "this guy mined 12.5BTC from x block".
The start of every block begins with a Coinbase, this is a transaction that has null inputs but outputs a 12.5+fee amount to the creditors' public key/address.
They're trying to get a hash of the block to fall below a certain amount, this was originally done by chainging the nonce in the coinbase (which is an up to 20 byte number that is stroable in any transaction before it's signed).

And then how my blockchain file will be shared to all the other blockchain files of the world? So the network will confirm that I really earnt 12.5BTC.
The block gets shared with new nodes and is sent to them as a packet. If you use a mining pool this is handled by them, but essentially, when you run an instance of a miner it will normally have to connect to a full node where it gets information of what it has to put in the block and also publishes the newly found block to other nodes. This needs alright connection to the internet since each block has to point to the last block in it's header and give the height of the block it will be.

These funds take a day to become spendable, for standard nodes on the network that conform to current rules.

Now about the transaction fee. When I send 50BTC to an address with a fee of 0.002BTC, does this mean that I write publicly something to the last block?. Since there is no main database of bitcoin transactions, how will the blockchain updates that I want to send x number of bitcoins to an address? And then miners see the last block's transactions and choose what transaction to solve. I know that if they solve the transaction hash (?) they will get the fee as a reward. But what exactly are they trying to do in order to solve it?
When you broadcast a transaction to neighbour nodes, they will verify it and continue it's propagation through the network.
These transactions are collated and added to a block which then has it's information changed more than 1000 trillion times a second in order to find a number below the target nonce.

4) What is a target and why the block's header must be equal or lower than this number?
In our wiki we have written what's a target: https://en.bitcoin.it/wiki/Target
The thing I don't get is here:
Quote
Each hash basically gives you a random number between 0 and the maximum value of a 256-bit number (which is huge). If your hash is below the target, then you win. If not, you increment the nonce (completely changing the hash) and try again.

If my hash is below the target?? The hash is a string and the target is a 256-bit number right? How to compare a string with an int?
Examples
(Hash: 9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08
Target: 0000000000000000001320bc0000000000000000000000000000000000000000)
Take this a bit simpler if you want, and use a target in real terms...
If your target is simple like 512 and you have a function that gives 2048 outputs, you're after running it 4 times on average to get below 512.
You can also look at trying to convert hexadecimal into binary since that's how the block hash is stored as it's probably better to watch a youtube video on it.

Essentially it's like normal numbers but with a base of 16:
(Hash: 9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08
Target: 0000000000000000001320bc0000000000000000000000000000000000000000)
would mean the hash is far from the target, however: 0000000000000000001220bc0000000000000000000000000000000000000000 won't be.

5) If I want to send 50BTC to an address with a fee of 0.0002 do I spend 50.0002BTC and the receiver gets 50BTC or do I send 50BTC and the receiver gets 49.9998BTC?

No, bitcoin was developed well.
10^-8 of a bitcoin is stored as a 1 (and is known as a satoshi) this may be subject to change but is currently the numbering system used.
You spend the full
500(00020000), they get 500(00000000) and the 20000 goes as a fee to the finder of the block.

The $7500 looks wrong because you picked quite an extreme example.

2x75=150 dollars in margined position
50x150=7500

BTC amount earnt will be a bit lower due to readjustment for the current price, you're selling the $100 and buying back at a higher cost.

Value and position in my example are the same. Position margin is then position + margin (so the position*leverage).

4373  Bitcoin / Bitcoin Discussion / Re: 5G & Bitcoin Risks? on: April 18, 2020, 02:38:17 PM
Are you saying we have already people using the 5G network? I read sometime ago that it was harmful and several Environmental analysts were campaigning against its installation and it seems it is already in motion. Wow, I have even read documents linking a theory of this pandemic to the secrete installation of 5G network. I guess I need to do a bit of more research about this.

People use 5g and no it isn't harmful to anything. Environmental analysis have issues with everything physical and organic scientists are fine with.

I'm told:
The intensity of 5G won't exceed the current cosmic microwave background radiation (cmbr)
The coronavirus can't be caused by an electromagnetic wave... There's just no way.

The first problem with the theory of covid19 being caused by the wave is thst the virus will be completely unaffected by it, much like the virus being invisible because its half the size of a blue light wave is similar to thst with coronaviruses - they can't even absorb the energy.

Current microwave radiation can be used to heat things up but cell damage at current levels is almost impossible and we've been experiencing the same radiation for millions of years as primates...

If you check sources, check things with viable facts... Look at what physical and organic scientists are saying, don't spend your time looking at conspiracy theories Bob the flat earther invented in his garage while shooting heroin (random names and procedures not based on anyone in particular)...

A theory is a theory until it's proven and then it becomes a theorem and eventually a law once it isn't disproven and accepted as a standard for long enough.

We know for sure though that 5g radiation will have much less of an affect than other things such as sunlight and any light... And we can't exactly get rid of all forms of electricity...
4374  Economy / Trading Discussion / Re: Bitmex Long/Short formulas for excel backtest on: April 18, 2020, 11:51:12 AM
Actually it's exit minus entry in the system:

So a long at 100, sell at 150

150-100 * 2 * 75
(for longing 75 contracts).

If you do a lot of continuous trading, then the realised pnl can go up a bit but you could always neglect it and test out a strategy with a small amount of funds...

Number of contracts bought is known as the "position" or "position margin"
Value in my terms was the initial margin so the amount actually on the position of your money (in this case the 75).
4375  Bitcoin / Electrum / Re: BTC has yet to show in Electrum Wallet - Please Help! on: April 18, 2020, 02:59:53 AM
If you load up electrum what does it say in the bottom left? Does it have text or does it show a balance of 0?

If you go to the addresses tab, can you see the address you attempted to send to and post it here (cross reference with a confirmation email to check it's right if you want too).
4376  Bitcoin / Electrum / Re: Be careful when copy-pasting a Bitcoin address on: April 17, 2020, 08:08:26 PM
This can be done with a botnet if necessary to produce addresses and send them out (vanity gen allows for running with a partial key too so others can't decrypt).

Or a pregenerated list of addresses that are probably not too big. Try to remember the first 5, copy paste, then check the last five before hitting submit.
4377  Other / Meta / Re: Domain name update on: April 17, 2020, 07:48:39 PM
To clairfy is there a co-ownership of both domains still or is one just owned by a single entity from now on?
Theymos owns bitcointalk.org, Cobra owns bitcoin.org, neither of them(theymos and cobra)has access to the domain name owned by the other.

No I meant more if it's possible to have a co-ownership here? Maybe Theymos, OG and hilarious or something - since there was a co-ownership in the past. (or theymos and cyrus)

If the co ownership was merely so that each could add different functionalities then this is unneccesary but if it was to protect the integrity of the domain and allow for it to be inherited wherever neccessary.
4378  Economy / Economics / Re: China’s economy is contracting and this is not good for the global economy. on: April 17, 2020, 07:39:56 PM
I still beleive that chinese economy will recover soon. Like many other economies in the world they are suffering at the moment and have the bigest GDP fall since 1992 but I think that unlike many economies in the european countries in the world they will be back to feet very soon and US and Europe will need much longer period of time so Chinese will have advantage once more.

I don't actually think this is the case.

We've seen china drop by about 26% and then rally back, we've seen Europe do the same and while I'm in no doubt Europe can fall further (potentially 25% - as estimated) the US may stand to lose a lot more... Grouping the two together disregards the semi-stable wealth production in Europe and the bubbled assets in the US.

4379  Economy / Trading Discussion / Re: Bitmex Long/Short formulas for excel backtest on: April 17, 2020, 07:32:53 PM
Bitmex has a few options when it comes to the parameters for trading (and I'm not logged  in and my second authentication key is far away so I don't know it for sure).

Two options for example though are index and last:
If index is ticked, this means the contract follows the index price and pnl is calculated using that (there's a formula but it's mainly the average of the 3 main leaders for btc pairs).
If last is ticked, then things execute as the last value reaches this price point and pnl is calculated from the furthest distance from it's direction (or something like that).

Your realised pnl and unrealised pnl are two completely different things too:
Realised pnl is what is deducted from your account as a fee for keeping the position open and it's very difficult to calculate as it dynamically changes.
Unrealised pnl is what you stand to earn or lose if you close the position now but while the position is open, this just affects your overall balance (hence why margin balance is higher afiak).

The actual formula for unrealised pnl is (entry - exit)*margin position
margin position = value * leverage * direction

direction = - (sell/short) / + (buy/long)

I know Cobra was holding both domains in the past, has bitcointalk.org just been transferred to you and that's it or is it controlled by an additional pool of people?
