I usually only consolidate unspent outputs funding the same address... In any case I never consolidate unspent outputs funding "anonymous" addresses together with unspent outputs funding "public, known" addresses. Like previous posters already indicated: it's usually a good idear to consolidate since you can potentially save on your fees later on.

It's not your account that is banned, it's you as a person. If you have one account that is banned, you should consider all your accounts to be banned.
The only exeption is that you can create one (1!!!) new account (or use an alt account) to create one (1!!!) thread in the meta subforum to discuss your ban.

If your original account was banned before 30 juli 2018, this post could be considered as ban evasion... If your account was banned after the 30th of juli, it isn't ban evasion as long as you make no more posts outside this very thread.
Since your original account's last post was made on the 16th of juli, there is no way we can know if this is a case of ban evasion or not.

this ^^.
I'm not a merit source, but i have tons of smerit on my account... However, i can't find <Hero members that make half decent posts. I refuse to give out merit to posts that don't deserve it, and 99% of the lower ranked members are just spreading FUD, posting news articles, spew out utter nonsense, make unreadable gibberish sentences,...

The result is that more than half of the merit i DO give out is to members that don't actually need it...

most coin daemons have a json-rpc interface, i doubt anything happens manually... I think that exchanges will probably automise the process, or even just use the json-rpc interface of the daemon whenever you want to view your balances? The daemon can also use a hook to call a binary whenever a block contains a transaction that funds an address managed by their wallet, it doesn't matter if the daemon was down, upon syncing it'll just keep calling the hook everytime an incoming tx is found in a block.

Offcourse, there is no way of telling how an exchange works internally... Do they keep a seperate relational database with user's deposit/withdrawal records, do they run customised daemons,...

I'm sorry, but there were so many half truths and errors in this reply i just had to correct you:
You can't use a computer to mine anymore, you use a recent ASIC. The diff has been waaaaay to high for many years to allow mining profitably with a computer.

A recent ASIC is pretty easy to configure.

You don't need to register to the network (if you solo mine, you just collect broadcasted transactions in your mempool and receive new blocks... Based on the block header of the latest block you received and the unconfirmed transactions in your mempool, you can generate a new block header and try to solve your new block without registering your ASIC... Only when you solved a block, you need to broadcast it to the network), you don't HAVE to join a pool.

If you're not solo mining, you don't always have to register for a pool... There are pools that allow you to mine without registering (usually, you just use your withdraw address as a username and that's all)

Thanks for the feedback
BTW... Seems like systematic abuse.. The first report was his very last post, this is the previous post he made... So at least the last 2 posts he created were plagiarised:
original: https://bitcointalk.org/index.php?topic=4677867.msg43180375#msg43180375

plagiarised but with synonyms: https://bitcointalk.org/index.php?topic=4677867.msg43186158#msg43186158

Just a quick question... I noticed this user:  "bubble pop" (https://bitcointalk.org/index.php?action=profile;u=1114040)

He made this post: https://bitcointalk.org/index.php?topic=4750303.msg43323810#msg43323810

Directly above this post, user Direwolve735 made post https://bitcointalk.org/index.php?topic=4750303.msg43323189#msg43323189

At first sight, these posts look nothing alike, but upon some investigation, it looks like Direwolve735's post was run trough a synonym tool... (Allmost) every word in Direwolve735's original post was replaced by a synonym... Or am i hallucinating? I collored the synonyms in equal colors, and the same words in bold.

I haven't dug trough this user's other posts, so no idear if this was a one-time thing, or if he's systematically doing this.

Here's the archive of the original thread's page: https://web.archive.org/web/20180802105308/https://bitcointalk.org/index.php?topic=4750303.180;topicseen

Is this ban-worthy or am i just seeing things that aren't there...

Not an exact answer to your question, but i've bought my case from fasttech... Dirt cheap and you can pay using crypto (i can vouch for this)... IIRC, if you look at these cases, some have images with the actual specs.

https://www.fasttech.com/category/1017/raspberry-pi

For example, this one is available for loads of models:
https://www.fasttech.com/products/1017/10013654/7219800-protective-plastic-box-enclosure-for-raspberry-pi
You can pick this brand for different models by using the dropdown at the right... Altough i could only find this case for a B+, not a B (i don't know if their form factor is the same)

Even if the form factor is wrong, you would have only lost two bucks

Thanks for the feedback
If you want to test the lightning network on the testnet first: let me know, I also have a testnet version

the whole article was a bit TL;DR, but i've browsed over it, and i can only say this: They should have banned those apps a long, long time ago. It seems they're not banning cloud-mining apps, which is a petty... They should have banned those to.

The performance of cellphone CPU's/GPU's is just poor (the power usage vs hashrate).

In this post: https://bitcointalk.org/index.php?topic=4750303.msg43133494#msg43133494 I calculated the YEARLY income of cpu mining bitcoin on a cellphone to be ~2 satoshi/year, so you'd have to mine for about 250.000 (twohundred and fifty thousand) years to reach the MINIMUM payout treshold most pools have implemented.

Cellphone mining apps are either a scam, are not really mining (like some altcoins that claim to be mobile-minable, but they just give pre-mined coins or tokens for you to run a "miner" while they show you adds or use your phones resources for other things) or are completely and utterly useless

Hi guys, i just finished writing a walktrough on how to download, initialse and fund eclair 0.3.5 on android, then open a channel and pay a very small fee on my mainnet lightning demo site... I wondered if anybody had some feedback for improvements? AFAIK, it's one of the first walktroughs for lightning payments on the mainnet, so i'm not sure if it's complete and newbie-friendly enough...

If nobody has any feedback, i'll probably start linking to the walktrough this evening.

http://www.mocacinno.com/lightning/walktrough_eclair_android.php

The walktrough is 100% SFW, the site itself has 1 active publisher that published a couple soft NSFW images (so if you click on the NSFW subcategory, there'll be some semi-nude thumbnails... But if you aren't actively searching for those the site should be ok to use in a work environment)...

I'm afraid most mods won't make the effort of correcting these users... What i usually do is just put these users on ignore, and i hope many other senior members do the same. This way, these spammers will have less chance of receiving merits, so they'll probably never reach a rank higher than Jr member (eventough this particular one was lucky enough to be a member when the merit system was introduced... However, since then he doesn't seem to have gained a single one). I just hope that when they are locked in a lower rank, they'll give up sooner or later....

Anyways, i'm happy to see at least one person took the time to read my post

Since my last post clearly outlining why bitcoin should not be mined with a smartphone, not now, not in the future, people still keep posting in this thread. It's still being treated like it's an opinion piece while in reality this thread should rely on simple math.

Since my previous post didn't do the trick, i'll simply do the maths proving once and for all that mining with a cellphone should not be done...

Let's take a "normal" cellphone CPU: a Cortex-A9. https://en.bitcoin.it/wiki/Non-specialized_hardware_comparison#Other teaches us this CPU is hashing at a whopping speed of 1,3 Mh/s. If you underclock this CPU and it runs at 0.57 Mh/s, it draws 0.5 Watt. Let's just assume that making this cpu hash @ 1.3 Mh/s also draws 0.5 Watt (eventough it won't).

Let's take the current difficulty of 5949437371609

Let's take the current block reward of 12.5 BTC + 0.12 BTC in fees = 12.62 BTC

Now... Let's plug these numbers into the formula to calculate how much BTC you'll mine on average with such a CPU:
(((1300000 * 12.62  * 600 * 65535) / 2^48) / 5949437371609) * 6 * 24) = 0.000000000055 BTC/day = 2 satoshi per year!

An "average" pool seems to have a payout threshold of ~0.005 BTC (https://www.f2pool.com/help/?). So, in reality, it'll take 250000 years to reach the minimum payout treshold.

If you decide to solo mine, it'll take (on average) 631.000.000 years to solve a block (yes, that's 631 million years).

During these 631 million years, you'll have burned 2,7 TerraWattHour, i doubt the block reward will cover the power costs. Do realise that every 210000 blocks, the block rewards will halve... Cutting in your profits.

Now for the people continueing to claim that in the future you'll be able to mine with your cellphone: just look at the above formula... If, some day, cellphones will have chips that are as performant as current ASIC's, the ASIC company's WILL have access to the same technology. An ASIC is built for the sole purpose of creating sha256d hashes, it will ALWAYS be more performant than a CPU...
So, in the future, the only 2 things that can happen are:
- bitcoin might be worthless, so ASIC companies are not interested in creating new ASIC's, the future CPU's become more performant than the old ASIC's and you'll be able to mine worthless coins
- if bitcoin prices continue to be this high, ASIC companies will use the new technology to create new ASIC's. In this case, the network's hashrate will rise exponentially, the diff will rise, so the number 5949437371609 in the above formula rises exponentially, making it impossible to mine with new cellphones due to the high diff

If you get a ban, it's you (as a person) who is banned... This includes any account you own.
The only thing you're allowed to do after being banned is open one (1) thread discussing your ban in the meta subforum. If you use any alt account to continue posting while being banned, you're ban evading (which is, in itself, also a bannable offence).

Back on topic, i see nothing wrong with having multiple accounts IF they're not used to troll, shill, self-bump, self-vouch,... I think there are several use-cases in which it would be ok to have multiple accounts:
- one anonymous account, one doxxable account
- one account with an easy password for when you're on the road, one main account with a hard password for when you're behind your desk
- an account for branding purposes (if you own a business and "claim" the account that corresponds with your business name)
- ...

We're in the bitcoin mining subforum.... You can not make any profit mining with a GPU.
IF you want to mine profitably, you'll need a latest gen ASIC, a very low power price, big starting capital and a (semi)dedicated mining room.

If you got your hands on some of the best GPU's, at current diff and BTC price, you'd make about 14 cents a year mining 24/7... Offcourse, even if you only pay 5 cents/Kwu, the power company would charge you over 65 dollars for the power you've used while mining, making your net profit minus $65.

I've waddled trough 4 pages and tried to read most replies... I tought about just letting this thread pass by, but since i've seen nonsense being spewed, even by longtime members, i had no other choice than to set the record straight.

I would propose that everybody tries to read this post (i've tried to make it as newbie friendly as humanly possible, even if it meant oversimplifying) and ONLY post in this thread if you have LEGITIMATE questions about my post or if you have PROOF that i messed up. If there are no more questions, or if you fail to deliver proof that my reasoning is wrong, please let this thread die in piece (this topic has been discussed to death anyways).

(part of) The theory
In order to mine a block, a miner makes a new block header by taking the sha256d hash of the header of the previous block, adding the merkle root of all transactions in the block he's trying to solve, adding some other data that isn't interesting for this post and adding a random nonce (usually incremental). In order to solve the block, a miner increments the nonce and then executes following formula: sha256(sha256(new block header)). If the result of this algorithm is under a certain target, the block is considered to be solved and can be broadcasted to the network. If the result of the algorithm is over the target, the miner increments the nonce and tries again.

The target value is determined by the difficulty. The bitcoin network adusts this difficulty everytime 2016 blocks were solved (about 2 weeks). The difficulty is adjusted upwards or downwards to make sure the average time between 2 blocks is 10 minutes. So, if a lot of hashrate would be added to the network, the difficulty would shift upwards after a maximum of 2 weeks, this rising difficulty would make the target value lower, making it harder to solve a block.

My answer to the misconceptions:

• Calculating a sha256 hash isn't really hard to do... You can even mine using a pen and paper... HOWEVER, since the networks hashrate is soooo high, the difficulty is sooooo high and the target is sooooooo low, the odds of finding a block are incredibly small (you would need an army of about 130.000 skilled mathematicians to create 1 sha256d hash result a second... By comparison, an antminer S9 creates 14000000000000 hashes each second). So, all in all, a cellphone's CPU or GPU *could* create sha256d hashes, however, the odds of ever finding a block, or even generate enough shares to get the minimum payout @ a pool are incredibly small... I once calculated you'd have better odds of winning the lottery several times in a row than than finding a block with your cellphone. In reality it's better to say it's impossible to mine with a cellphone/cpu/gpu... It makes life easyer for everybody
• In the future, it's indeed possible we move to 7 nm chips, and your cellphone becomes more powerfull than the PC you're using today... However, there is no reason to assume ASIC producers wouldn't follow the same technological trends. In other words: by the time cellphone companies are using 7 nm tech, ASIC producers will probably have switched to the same technology... Since an ASIC is generated for the sole purpose of creating sha256d hashes, it'll always be thousands of times more powerfull than a cellphone. They'll just push the difficulty to a level even future cellphones can't reach. So everybody saying: 'in the future you'll be able to mine bitcoin with your cellphone' => i'm sorry, but the odds of you being right are extreeeeemly small
• it's true samsung created a mining rig out of old cellphones. While their hashrate was higher than running one of those novelty mining apps you can find in the playstore, the power consumption vs the hashrate was still very, very, very, very poor. The hashrate in itself was really low to... So while it was true that samsung created such a mining rig, it should be considered as a proof of concept, something to show off with, or maybe a learning tool for samsung's engineers... However, you can not treat this samsung project as a legitimate mining project

Last but not least, i wanted to raise 2 extra points:
1) it's perfectly possible some altcoins could be mined with your cellphone/cpu/gpu... But we're in the bitcoin mining subforum.
2) if you want mathematical proof, check out my website: https://www.mocacinno.com/mining/ . I've included a couple mobile cpu's because this question keeps on surfacing, and i wanted to proof to everybody that is spewing out nonsense that it's NOT a good idear to mine with your phone. For example, at current diff, mining with an ARM Cortex-A8 (a common cellphone CPU) in a pool would make your less than 1 satoshi per year...

Nobody is saying you're a cheater, however : most long time members have seen dozens of newbies offering micro payments for tasks and dissapaering once it"s payday... So everybody should be cautious...

Want my advice? You offer a bounty of $82 at current preev rate... I would advice you to buy some btc or ETH with fiat and escrow these funds with a trusted escrow. Once people see those funds are being helt by a trusted member, newbies will probably flock to your offer.  Not having $82 bucks right now isn't a real excuse imho.

Whatever you chose to do is up to you tough

Electrum is a decent wallet, but i would never go as far as calling it the "best wallet for bitcoin". Electrum, like many other wallets, have had their fair share of bugs that could have been used in various exploits.
ThomasV is a decent guy, he stands behind his software and is a valuable part of our community, but he's still the only "real" dev of electrum (AFAIK), a desktop wallet... Even after all his hard work, i'd still prefer a hardware wallet over electrum.
Offcourse, i do use electrum as a gui for my hardware wallets, since electrum's feature set far exceeds that of trezor's web wallet (for example).

You shouldn't be paying a flat fee per value, you should be paying a fee per byte of transaction data (it doesn't matter which value you transferred, a 0.0001 BTC transaction can be LARGER than a 100 BTC transaction, thus requiring a higher fee eventough the transmitted value is 1000000 times smaller).
All that matters is the number of unspent outputs that have been used as an input of your transaction, the number of outputs generated by your transaction and wether or not you're using a segwit wallet. There are other parameters that can also influence the transaction size, but they shouldn't matter for a "normal" user.

IF you had to pay a 0.005 BTC fee, it was either several months ago (during the spam attack) OR you were spending from an online wallet that uses a bad fee estimator OR you were spending hundreds upon hundreds of unspent outputs.


I haven't got a clue what you're trying to say, sorry... But if you're telling people thay should use a low fee, you should rethink this. The fee is the difference between the sum of the inputs and the sum of the outputs. A miner can add the sum of all fees of all transactions he includes in the block he's trying to solve to the coinbase reward of 12.5 BTC (at the moment). The more fee per byte of transaction data you add, the bigger he odds a miner will include your transaction in the block he's trying to solve.

At the moment, adding a very low fee is fine. But if you continue adding a low fee during a spam attack, your broadcasted transactions will probably never end up in a block (unless you keep rebroadcasting them for months). Most nodes prune unconfirmed transactions from their mempools after a couple of days, lowering your odds of getting your transaction confirmed.
You should advice people to use the appropriate fee at that moment in time. At this very moment, a 1 sat/byte fee is fine... In a couple of months it *might* be 100 sat/byte (who knows). I've had to add over 400 sat/byte in the past in order to have a decent chance of my transaction ending up in the next 6 blocks...

nope... you're talking about priority transactions (https://en.bitcoin.it/wiki/Transaction_fees#Priority_transactions), but allmost no miner will add 0 fee transactions to their blocks anymore, even if they're priority transactions. A 0 fee transaction won't even make it to the mempool of a lot of nodes. So, theoretically it's possible to have a 0 fee priority transaction included in a valid block, but the odds are not in your favour.
