@lucius: Sure, i do feel for people making only a couple bucks each month... That being said: will those people be able to affort a device to surf with, internet access and power?
It seems to me that if you only make $8/month (Venezuela), you'll have to save ALL your earnings for several years to buy any device capable of surfing...
Even if the minimum wage in their country is sooo low, and by some miracle they succeed in buying a device, internet access and power, i'd still discourage them from airdrops (because they fill the forum with unneccesary bogus), cloud mining (because the scam factor) and social media (because there's a risk of them participating in a ponzi).
I do agree with you that my situation isn't the same as other people's situation, and i apologise if somebody from a low-wage country got offended by my post

Hi JTO... The thief robbed you using transaction 2e9499320568eb64dc695928b3cf4b409c97a61e5dc6a9574dae4c8e703c0a8e From this transaction, we can deduct following address are part of YOUR wallet: 18bFg7hr1RD5CGd1Xjx61QKF3C3Db5KD6h 18ycmB63hbXJT4XvmGBMCeHkuDMNSSXoQH 1FvotYR8JZQY7huz6diA3T4RtpmwcUyh4K We can also deduct following address belongs to the thief: 1EdnLXoWy2DJnwgJbvzGRH72Wx2VYxYzDV By tracking 1EdnLXoWy2DJnwgJbvzGRH72Wx2VYxYzDV, we can see that the thief used his stolen funds to fund addresses 14Vc3rodXBCAMR8NXYJDzSv6X9FKVXxQ4e 16YJ7uM8rwvXvA1o2YSdgvEsiHRT32Ma1j using transaction 8e90f919752de1d35cb4ef83a2582ab3cc9de443c9aaf8fee20a2da6dad72654 The first stolen unspent output is not moving and is still funding 14Vc3rodXBCAMR8NXYJDzSv6X9FKVXxQ4e The second address (16YJ7uM8rwvXvA1o2YSdgvEsiHRT32Ma1j) belongs to a wallet controlling 1AG9AeU6qW7Vzf61W369eS4if36mVJr8Ph 15txy8sNsXKAh9AxB3u43ULAzJChi1YqTn 13LeePnHr4FHwF9CcH8TcyW3tSC2vJKPJ5 1JDuTYYeijnQDeiwiZw6VeHGtDU1aYKjCS 1GjgiVuZvkpxcG5MajPTqFV422hs9cXFnB 16YJ7uM8rwvXvA1o2YSdgvEsiHRT32Ma1j 1PGpArCFdWBqpt5tBA5AaEBnKLA4ZsQion 1H8Z4dF9SpPmpwVq2GW6sniByQvDu628tg 1FBKjhvzFcmWzLDsuTWtp6Fm16Yi3CoRt 1QKmQne8UQNV2CnYpMS6YfD5EHqGi4rXt5 17rT7wXr4VD7q4BWoKqbqM1F4tRbjW2SCo 12UmS7bNbCK1Tf3feFw5CQWniK6WxzNbDQ 15w8r6NkLuVg78uuWsBEYxEwvxVrmqnHVB Since unspent outputs funding all these addresses were spent together in transaction f80a17289695a02f1478f193afe73722305bc225d9d12fd3c1269c94b29d191a This transaction funds addresses 1MDgeDBEZJxKMFy1x6xQzHS4v5Sjhdk3Si and 1NBWjyCYcwfhyaqgQMzyagUgegSxrW2oYM 1NBWjyCYcwfhyaqgQMzyagUgegSxrW2oYM belongs to a rather extensive wallet, controlling dozens of funded adresses: https://www.blockchain.com/btc/address/1NBWjyCYcwfhyaqgQMzyagUgegSxrW2oYMNow... What does this mean to you?A) 1EdnLXoWy2DJnwgJbvzGRH72Wx2VYxYzDV certainly belongs to the thief... If you ever find somebody posting this address, you can link it to a name B) 14Vc3rodXBCAMR8NXYJDzSv6X9FKVXxQ4e and 16YJ7uM8rwvXvA1o2YSdgvEsiHRT32Ma1j *probably* belong to the thief... Altough one of them could be a mixer, an exchange, a casino or some serviceprovider and the other one could be a change address... Altough the amounts seem strange to me... If i robbed you, i'd either try to wash all the stolen funds, or i would wash none of them. My gut feeling tells me that 14Vc3rodXBCAMR8NXYJDzSv6X9FKVXxQ4e is probably an address belonging to the robber, and 16YJ7uM8rwvXvA1o2YSdgvEsiHRT32Ma1j is either an address belonging to the robber OR a service provider. If somebody posts either address anywhere, this person is either your robber OR somebody that got payed directly by your robber... So you can tie those addresses to a person C) IF one of the other addresses ever get posted, you can try to work your way back to the owner of 16YJ7uM8rwvXvA1o2YSdgvEsiHRT32Ma1j and then use this owner to find the owner of 1EdnLXoWy2DJnwgJbvzGRH72Wx2VYxYzDV ... Anyways, it becomes a longshot. |

Here's the part where you mess up/get confused ~snip~
There is a big chance of getting the same output from different inputs.
~snip~
The output of a sha256 hash function is 256 bits. The odds of a sha256 hash collusion are astronomically small. You'd have to find a merkle root hash (so a complete merkle tree), timestamp, and nonce for which the sha256d hash is equal to the sha256d hash of the original block... That's allmost impossible. I've googled around, and found this example: source: https://stackoverflow.com/questions/4014090/is-it-safe-to-ignore-the-possibility-of-sha-collisions-in-practiceFor instance, with SHA-256 (n=256) and one billion messages (p=109) then the probability is about 4.3*10-60.
A mass-murderer space rock happens about once every 30 million years on average. This leads to a probability of such an event occurring in the next second to about 10-15. That's 45 orders of magnitude more probable than the SHA-256 collision. Briefly stated, if you find SHA-256 collisions scary then your priorities are wrong.

Thanks for the sample posts... joniboini is probably right, i'm not sure if there is a market for these items on bitcointalk... But it's certainly worth a try. Posting on bitcointalk is free, so there is no reason not to try. I'd suggest 4 things: - post "different" pictures. The pictures you post now look like stock photo's, people on this forum need photographic "proof" you have these items in stock. They don't need to look at stock photography (if they want to see a stock photo, they can use google to find one). Post a picture of the items you have in your store and place a piece of paper with your forum username and today's date in front of the items when taking a picture
- offer the use of a forum escrow
- never ever try to move the discussion to skype, telegram, phone, email,... Keep all conversation on the forum in plain sight. People like me think it's fishy when you try to move the conversation off-forum (it looks like you're hiding something)
- You can always try to give some vouch copies... I know it's an expense for you, and it's not certain you'll gain some business... But nothing beats a green trusted, long-time member vouching for your product. Don't give vouch copy's to just about anybody, only give one to longtime, very trusted members that have some kind of link to the product you're selling. In this case, it would be a good idear to find a DT member who's into cooking to send a free saffron sample.

Well, this is nothing new... It's been known in the community for years, and i guess it's even common knowledge for "mainstream" people after the silk road founder was caught and jailed years ago. All newspapers in my country reported how much bitcoins were seized from him, so every man in the street that has any interest in the dark web or crypto currencys at all has known the use of crypto on darknet markets for years... I don't know why it comes as a suprise to some people in 2019.
That being said: a lot of the adds on those darknet marketplaces are real... Some are fake, some are honeypots, but a lot of them are "genuine".
Also, bitcoin is pseudo-anonymous... If you don't know what you're doing, and you're using it to buy stuff on a darknet market, there is a decent chance you'll end up on a suspect list of a 3 letter agency sooner or later. Some marketplaces have switched to monero because of these anonimity-issues.
Disclaimer: i'm not a darknet user anymore. I've run some hidden services for LEGAL websites for a couple of years (but they're all down now), and i've visited several darknet markets in the past to see what the fuss was all about, but i've never purchased or sold anything illegal, not on the darknet, not on the clearnet, not IRL.

Sorry, i mean you can get $25 worth of XLM
Are you sure? They spammed my email with their offer to, but i think the mail i received indicated they were talking about 25 XLM (i deleted the mail from my mailbox, since i do not tend to hold on to spam mails)... I searched for the claiming procedure and found out they want a complete KYC for 25 XLM, so i walked away. But it's possible i misread and they were talking about $25 in XLM... Still not enough for my privacy, but certainly better than $2  |

Well, a link to one of your efforts on bitcointalk might help us pinpoint the problem.
A payed subscription will only allow you to post pictures and reply to your customers a bit faster, but don't expect some "magic" to happen if you buy for a copper membership... It'll make your life a bit easyer, but i don't think it'll increase your sales by a lot.
The best advice i could give you is to clearly state in every thread that you will always use a trusted forum escrow to hold all funds your receive untill the customer indicates he or she received your items. Without using a forum escrow, it'll be nearly impossible for you (as a newbie) to conduct any business on bitcointalk at all.

Altough, theoretically, most of your points are correct, i would still like to add some remarks to each of the points you raise: 1. Faucet
You can get any coin with claim it every 1 hour,1minute or no waiting time. Like freebitco.in and freedoge.co.in or Faucethub.
Altough i haven't tested out a faucet in years, i quickly browsed to faucethub and found the average claim seems to be around ~100sat nowadays (i did not do the math, i just looked at the list and remember that most faucets don't actually give you the amounts they claim in those toplists). I remember that due to the hidden links, captcha's, popups, fake faucets, dry faucets,... It would be a miracle if you were able to claim more than 50 faucets per hour. This would make your average "income" 5000 sat/hour... That's about 18 cents/hour. In my country, the minimum income (after taxing) is about 7€/hour. Working on an assambly line or at Mcdonalds would be about 40 times more efficient than claiming from faucets. Next to this, working at a factory or a fastfood joint wouldn't require you to invest in a pc, electricity, internet,... It would also give you access to social benefits like insurance, and you would actually contribute to the growth of your country. My advice: get a real job, buy BTC with part of your wage... Far more efficient 2. Airdrops
Its just like a giveaway to user who participate in their project. Blockchain give free XLM to their member who has tier 2 in their profile and some ICO creating airdrop to introduce their project.
They give 25 XLM AFTER you gave them your name, address, phone number, copy of your ID... My privacy is worth more than 25 XLM (less than €2) 3. Cloud Mining
Mining in website like EOBOT. You can claim GHS everyday to increase your speed mining in EOBOT.
There are only 2 types of cloudmining companies: - 99,9% are scams
- 0.1% are companies that sell you 100% of their risk for a very, very, very small part of the potential profits
The 99,9% and 0.1% statistics are not a result of an actual calculation... They are a result of my experience within this comunity and are more of a gut feeling instead of a "calculated" result. My gut feeling actually tells me that the 99,9% is actually an under-estimation. 4. Advertise
If you have website with good visitors, you can advertise your website with A-ADS. you can get bitcoin if your visitors click your ads.
Sure, i run a-ads on my sites to... But you'd need a site that gets thousands of unique visitors a day to make peanuts... I've been able to claim from them ONCE, and i run sites that do receive a couple hundred uniques a day for a couple of years now 5. Social Media
You can earn by posting any Story in Belacam. If other member like your post, you can get free coin.
Don't know this technique, but be carefull not to promote scams while posting things on social media!!! There are many more ways to earn free cryptocurrency to share in here. like a Bounty, View Ads, Take a Survey, Play a Games, Gambling and many more.
Bounty = a type of promotion that decreases everybody's bitcointalk experience IMHO. If you do bounty reports on bitcointalk, don't expect any respected member to take you seriously ever again View Ads = very low hourly income, get a IRL job instead Take a Survey = very low hourly income, get a IRL job instead Play a Games = very low hourly income, get a IRL job instead Gambling = bad advice... The house always wins. Sure, you can get lucky once in a while, but on average, the total group of players will always lose more than they win (and in the odd case the group of players wins more than they lose, the casino goes bancrupt and dissapears) |

If you want a quick and easy sollution, check out https://bitcore.ioIf you want to do it yourself, you'll have to run a full node and either use the json-rpc interface and build a custom api on top of it, or build a block parser, extract the needed data and build an api on top of this data |

No worries about the merits... I was happy to help I currently have a forum rank that cannot be increased any further by receiving merits, so i have no actual need for them... They're more like a badge of honour (at least, they are for me). I simply sent you a merit because you seem like the kind of guy I want to encourage to stick around, and you need at least 1 merit to move past the newbie-rank and all it's restrictions. Most newbies are spammers or scammers, but since your first post was a real question that doesn't get discussed several times a week, and was posted in a relatively well-chosen subforum, i just felt like you deserved to be able to rank up eventually If you have any more questions, don't hesitate to ask! |

Okay, I get it. Regarding your answer to the fourth question, I've read many places that donation or fund-raising addresses should be dynamic, i.e. generate new addresses every time someone requests the donation address. Does that only apply if I were to spend one of the UTXO i received as fund before the fundraising ended (i.e. I stop accepting funds to that address)?
That's actually a pretty good question... From a security point of view, i would say that, yes, as long as you don't spend any unspent outputs from a donation address, the public key isn't known to anybody but you, so it would be safe to re-use a donation address as long as you don't spend any of the unspent outputs funding it. Now, don't freak out if you re-used an address, at the moment it's still secure even IF your public key is known... I re-use my public address all the time (but i don't think i have anything to hide)  If you want to track who donated how much, you'd need to create a fresh address for each donation tough... Also, creating fresh addresses would allow you to spend some of the donated funds while leaving the rest untouched, while increasing the pseudo-anonimity (it would be pretty hard for somebody to find out which addresses were funded for donation purposes). |

Here's my take on your 4 questions... It's possible other people will have other opinions tough:
Can someone observing the Blockchain deterministically figure out A1, A2 and A3 belong to same user?
Well... He can't prove A1, A2 and A3 belong to the same user, but if you spend all unspent outputs funding an address to fund a single second address without sending change to a change address, one can assume there's a reasonable chance both addresses belong to the same person... But you will be unable to prove this with 100% certainty.
If Alice now spends A4 to Bob (sends all amount, she never uses A4 again), can Bob ever figure out that A1, A2 and A3 belonged to Alice?
That's actually pretty much the same question as before... He can't prove A1, A2 and A3 belong to Alice, but he can have a very strong indication that this is the case
What privacy will Alice (or someone down the trail, like Bob) lose if she goes for option 2?
That's actually still pretty much the same question... If Alive had to fill a KYC form on an exchange and withdrew her exchanged FIAT to A1, a 3 letter agency will be able to deduce to a certain degree of certainty that both A1n A2, A3 and A4 belong to Alice. It's won't hold during a court case tough.
Is reusing addresses to only receive payments and spending that address only once okay?
It's not only OK, it's strongly recommanded. It makes it harder for other people to analyse the blockchain and increases your privacy AND it makes sure the public key of your address is only known to a thirth party AFTER you've spend the funds funding said address.

It's been a while since i last posted on this topic, but it filled with nonsense dribble once again... I guess no more than 25% of the posts in this topic make any sense (both gramatically and technically). Since newbies WILL be able to read this nonsense posted by higher ranking members, i have no choice but to set the record straight once in a while. Everybody spreading false rumours in this thread will go straight to my ignore list from this point foreward...Not possible. Why do you even want a feeless transaction? I thought the purpose of Bitcoin fee is to prevent spam/ddos. It's not even for the Miners as some suggest.
The fees very negligible by the way. It saves the network from attacks
The miner can add the sum of all fees of all transactions he puts in the block he's trying to solve to the coinbase transaction... So the fee IS for the miners (as some suggest). At the moment, the fees are neglectible, however, about a year ago there were fees upward of 400 sat/byte. To do it individually it is not possible but if you use another sites services they can send your bitcoin and take on the transaction fee themself.
Wot  Some casino sites such as the sports books I use do not charge you to send bitcoin off their site.
I also use a wallet for exchange when I send bitcoin from their site they do not charge any sending fees too.
Offchain transactions between two sportbook "wallets" *can* be free because they are offchain... It's just the sportsbook updating the balance of your account in their relational database. As long as they don't broadcast a transaction, they don't have to charge a fee. If they allow you to withdraw your winnings for free, they're the ones footing the bill... it has nothing to do with 0 fee transactions (which are technically possible, but very improbable). Absolutely not, transaction fee is what miners use in making transactions easier and swift for different parties. Without this it won't be possible for bitcoin to be sent out or in.
On a technical level, there is no "in" or "out", just transactions spending unspent outputs from the utxo set, funding addresses so new unspent outputs can be created. A fee does not make it easyer for a miner to add your transaction to a block, it just gives the miner an incentive to do so. You really cannot tell that there was no free transactions available earlier, most of the online wallets used to transfer funds for free without any fees before the transaction charges started increases because of the block limit and getting to a consensus took a really long time which made a lot of difference on how bitcoin is adapted since, now every online wallet does charge you fees for every transaction and nothing is free now, If you are using your own wallet then you can send transaction with very minimal fees, less than ten cents right now but without any fee is impossible if you are planning to send your coins  . If you use the command line interface of core, the console of electrum, coinb.in,... It's still possible to create 0 fee transactions... The trick is getting them broadcasted/relayed and finding a miner that's willing to add them to the block he's trying to solve. As of now I don't have any incounter that there's no fee because most of in crypto have a fee if you do a transaction. And fee is the one thing they can use to develop their every platform.
Huh So, because altcoins are using fees, bitcoins must be using fees? I don't follow that logic. The fee does NOT pay the dev! Yeah, fees are here to make this market more secure. Its hard for a developer to run their system if there is no profit at all and chances are, they will just close the project. So fees is good sometimes, and its more affordable compare to other financial institutions.
The fee does NOT pay the dev! Always you pay transaction fees for transferring btc from one wallet to other wallet. Little bit of low or high. But must be pay fees.
But now I want to say about coinbase. Where they support transection btc Through coinbase email address. Where coinbase don't charge any fees for transection. And transection is instant. So I want to say it is the one way for transferring btc from one person to other without any fees. You can choose it. [ coinbase is an Exchange don't a wallet ] Thanks
Once again: offchain transactions *can* be free since they're just an update in the relational database of the online wallet provider |

Disagree, just like all the others... If this proposal would make it to production, and the *sshat that gave me -ve ever makes it to DT, i would show as having risked about 1 million BTC. I doubt anybody that wanted to do business with me would bother to check out his link and find out it's completely a completely offtopic, wrong and insane feedback from an a-level troll disguised as an honerable member.
There is no way to factcheck these inputs and avoid abusers to enter massive amounts without any proof...

it is you who see I sent image + files
you're all getting so ripped off that it's getting psychological.
The image proofs ONE of these things: - you know the basics of image editing and have a watch only, testnet wallet, or a wallet funded with 48 microbtc
- you have found an image of a wallet
- you own a wallet whose addresses are funded with 48 btc
The file proofs you know how to make an encrypted wallet. There is nothing that proves the images are real and the file you uploaded is actually the wallet depicted in your images. There are 2 attack vectors, and your nonexisting forum reputation does not protect us from either one: - The wallet you shared might not be the wallet you showed in the image
- If we send you 0.5 btc, nothing is stopping you from running away without sharing the password
If you're honest, you'll go first and just send the funds to whoever accepts your deal without sharing images or encrypted files... Confirmed transactions proof waaaaay more than images ever will... If you're afraid of getting scammed: use an escrow, or send 47,5 btc and keep 0,5 BTC, that way you don't have to trust your client |

The problem with this approach:
- We don't know what we'll be downloading.. It can be an infected rar for all we know
- Even if it's a valid rar containing a valid electrum wallet, we can't verify anything... Electrum encrypts the complete wallet, so you can be sharing an encrypted watch-only wallet containing nothing more but a list of addresses but without an xprv or imported private keys. Even IF the rar is valid, the wallet is valid and it's a real (not a watch only) wallet, we have nothing more than your promise you'll send the password as soon as you receive our funds.
As i've said: if you send me (or an escrow of my choice) the 48 BTC, i'll send 0.5 back as soon as the funding transaction has 10+ confirmations. I know i don't have a sufficient reputation to to trust me with 0.5 BTC, but your account certainly doesn't have sufficient reputation to send 0.5 BTC to your address with nothing more than a rar file that might or might not contain a virus.
I'll even make the deal a bit sweeter: i'll pay the escrow fee, and i'll send 1 BTC back instead of 0.5... As soon as the escrow of my choice confirms he's holding 48 BTC in escrow, and the funding transaction has 10+ confirms.

If it looks like a scam, smells like a scam and feels like a scam, it's probably a scam...
If somebody on the street asked you to give him $100 and promises you'll get $1000 back as soon as he's gone, you're not going to believe him either are you?
OP: i'm willing to take you up on your offer under these terms: send 48 BTC to the address in my bitcointalk profile (1MocACiWLM8bYn8pCrYjy6uHq4U3CkxLaa), as soon as the transaction has 10+ confirmations, i'll send 0.5 BTC back

Depending on the amount of coins you want to stake, an rPi might also be a good idear... https://medium.com/@monkas/how-to-setup-your-raspberry-pi-for-staking-multiple-wallets-c30d133a2ecdI've read a discussion on bitcointalk a long time ago, and if i remember correctly, an rPi should suffice for staking at least 3 coins, to bad i can't find the exact thread. This way, your setup will be very cheap, and your power consumption will be minimal... Offcourse, this setup won't suffice if you're staking dozens of coins. EDIT: after re-reading the thread, i noticed bathrobehero already gave the same suggestion... I did not delete this post because i think his suggestion was only made on the sideline of the discussion, and i think it deserves a bit more attention |
