There was another miner manufacture that provided refunds this way and people were upset. This was sometime in 2012 or 2013 or so. I forgot the name, might of been Butterfly Labs or so.
They basically cost like $5000 usd each, and BTC was like $10, so people paid 500 BTC for the miner, then 2 years later they issued refunds in BTC but at the original USD cost, so people got back like 5 BTC instead of the 500 BTC that they paid.
However I am pretty sure if BTC went the other way and hit $1, they would send the original 500 BTC back instead of the actual USD value of 5000 BTC.

The issue with a hardware wallet is that it takes a while to order it and wait for it to arrive. What do you do in the meantime to keep your crypto secure? Or what if you can't afford a hardware wallet? Also if you buy a hardware wallet, how do you know that the vendor is to be trusted? There were a few incidences of tampered Ledgers found on Amazon.
This is why you are better off just using a cold storage software wallet like Armory or Electrum. Because all you need is an old computer you never use which we all probably have.
You take an old computer, take out the wifi and bluetooth and that will be your cold storage which is used to sign your transactions and holds your private keys. Your online computer is only there for generating the unsigned transactions.
This is very easy to setup, its almost instant and its free.

Im using M2G Android Miner to mine Monero. But you need a lot of cellphones to achieve pc-like results.
Eg my S6 gets about 15 h/s, but my S9 gets 40+ h/s.
Its pretty bad that an S9 can get 40H/s when an RX 470 gpu gets like 1000H/s. The RX 470 can be had for like $50 on eBay and an S9 is still a pretty expensive phone. It also has a battery inside that will most likely explode due to the sheer constant heat of the mining. And right now its not profitable to mine with the RX 470, so mining with an S9 is even worse. If you really want some money and got some spare phones, just put them on Craigslist and sell them for cash and use that cash to buy crypto instead. Not really worth the headache and like the above poster have said, its a scam fad and the other phone miners are fake mining and you won't actually make any profit. You are absolutely right. I just mentioned these numbers to show how tiny they are. Phones just cant compete with pc cpus and gpus. But thats just because of the overhead costs, the hashrate per wattage ratio is pretty much equal compared to my 1080s on Monero. Nevertheless I wouldnt call it scam because it is what it is. Everybody can run the numbers and compare it to see it's not worth it out of a financial point of view. But it still serves the general idea of decentralization and for some it's just fun to see and try if something works even if it makes no sense. Btw my S6's temperatures arent that high. Just about 40-50° Celsius. They get way hotter playing mobile games for example. My guess is phone gpu causing most of the heat which isnt used for mining. But Im no expert, correct me if I'm wrong. I am assuming that the miner software you downloaded for your phone was using the GPU instead of the CPU to mine, since GPUs work better than CPU in mining. This is only a guess, I don't know anything about the M2G android miner. One thing you need to realize is that when someone is playing a high intensity game on their phone, they usually hold it in their hands and their hands are actually the heatsink and its what lowers the temperatures. When you put the phone on a wooden table and leave it mining for hours plugged into the wall, then it will have much higher temperatures. |

I've PM the original creator of this thread because he seems to be active since his last activity was in June. I told him to either lock the thread or just change the topic from Bitcoin puzzle to something along the lines of "Bitcoin Challenge" to combat the same question being asked over and over again whether this is a puzzle or not. If he locks the thread we might as well continue from the one created recently, https://bitcointalk.org/index.php?topic=5166284Hopefully he replies and complies. |

A theme topic, whatever often talked about on this forum, is the $5 hammer attack.
Many people suggest to keep your bitcoin holdings secret, thus preserving the anonymity of bitcoin to a certain degree.
But then you get sportsbooks asking for photos and passports, and god only knows what else.
If a sportsbook wants all this, I respectly suggest they change to fiat.
Which site are you referring to? Most crypto gambling sites at the moment don't KYC. The only time when a site might KYC is usually when there is a questionable source of the depossited Bitcoin. Basically it might of been tainted Bitcoins from some bitcoin hack and due to liability reasons the site might as for KYC for liability issues in case there is some investigation going on with those tainted BTCs. However this is extremely rare. Only sites that do KYC, is usually the scam sites which do it because its in the terms and they don't want to make the withdraw when a player has won big. Since they know that many people due to privacy reasons don't want to KYC. So if you provide more info about the site that asks for KYC we might be able to provide more info. |

Bitcoin is beyond 1 country's borders mostly, USA would just be regulating its own borders and people which of course every country can and does do. Its not going to vastly alter the BTC protocol anymore then China banning usage which is over a billion people. Ultimately BTC relies on not being centred or requiring roots in any one place, it would have run dry a while ago if it retained that traditional vulnerability I think.
All I really hear in the latest words is make sure to pay taxes and follow the law, nothing radical imo. I doubt they oppose growth in industry and technology.
I think that trump tweet and the Libra mess that was created this week was nothing than over-blown FUD. Bitcoin has existed for years and exchanges like Coinbase and Gemini have been in operation and the USA didn't have an issue. There are issues with certain gambling sites however and this is why certain sites just don't let you use their gambling site if you originate from a particular country such as the USA. Basically they say that Bitcoin gambling is not illegal but their legal counsel basically advised them to block deposits anyways from certain countries. This is mostly to avoid any regulatory hurdles that might be created by dealing with customers in countries like the USA. But the USA is far from banning Bitcoin itself. |

It doesn't take any electricity to run a mining pool. All you do when you run a pool is basically have the wallet open and you accept shares from your miners and when a block is found your split the reward based on the equal share count for every miner. This only uses some CPU power and not much else. It might be more dependant on larger SSD and RAM depending on what type of coin pool you want to run. From what I heard Ethereum will require more resources than some new alt-coin based on a Bitcoin clone.
It used to be profitable to run these back in the day but these days people just stick to the big pools. And usually won't switch to a newer pool due to trust issues and the fact that if there aren't enough miners it will take a long time to find a block.

I assume that you live somewhere in North America with 120V power.
There are a few ways you can get 240V. One way is to use the stove and dryer plug. Those are always 240V.
Another way is you can probably just join 2 seperate breaker outlets which are 120V. Now you should consult with an electrian first before you do this because I don't know if its going to be up to code and everything. So do this under your own risk.
But I believe the Stove and Dryer plugs which are 240V are basically 2 separate 120V joined together with a larger fuse. However the wiring is probably a different gauge so you will be stuck with a smaller 15A instead of the 40A which are used by Stoves/Dryer. Again I am not an expert so ask an electrician first.

The original poster of this thread back in 2015 should go back and change the topic of this title. Because we are getting the same questions asked over and over again and it creates alot of confusion when it says "Puzzle" in the topic while this in fact is not a puzzle.
A puzzle is something that you can solve with a pattern, kind of like solving some mystery.
However the way you solve these private keys is mostly by brute force and its no different than solving for any private key the only difference is that these are low entrophy.
So instead of this being a puzzle its more of a test of human coding skills and available CPU and GPU and FGPA hardware.

Honestly, who plays 0.25 btc hands on blackjack? That is literally 2.5-3 thousand dollars each hand, that is a huge whale move if I have seen one, normally in real life you sit on a blackjack table and you will realize the biggest is usually 50 bucks per bet, I rarely ever see a person betting anything more than that, keep in mind this is a regular casino blackjack table, not Las Vegas big 5 star hotel with insane entertainments type of table, which means this dude is betting so much that if he cashed it out to dollars, go to Vegas and bet on blackjack he would be treated like a huge whale even there as well among all other whales. If you are attracting that type of customers to just sit at home and gamble on a website than you know you must be doing something right.
If you think that this is a big amount, then you must be wrong because there is more than just 0.25 btc play on stake. It is a big amount for us but this is just some tiny pennies for big whale so it does not really looks big for them. You should checked on their few pages back there when someone bet huge amount and got profit here. It seems that you are new to gambling industry that makes you amaze on this kind of bet  0.25 btc per hand on blackjack actually very high amount and i'm sure it was not all in bet which mean the players playing with plenty of bets use 0.25 btc for every hand and imagine if the players playing 30 times bets or more with it then i'm sure this players can be called as the whales in online gambling industry I can make an assumption here that he is indeed a middle whale, because there is no way that I could bet 0.25 btc per games. This is too much for any normal players here. They can even bet this huge because of it is stake, I do not think that someone can bet this huge amount randomly on other sites. It must be really painful if they do not get paid. But on stake with really huge bankroll and with the same roof as primedice make this possible Its pretty much no different than any regular casino. Most of the people that go to a physical casino usually gamble a few hundred, maybe less than 5% or even 1% or so gamble in the 5 figure range. Most people usually get paid on a Friday and blow their entire paycheck by Saturday. However the casino maybe makes $500-$1000 off those types of players. When some rich businessman gambles its usually in the 5 figure range and they usually have a special room for those betters. And it comes with huge perks whether they gamble or not. From what I heard they get a free hotel stay, free dinners and free excusions. The casinos most revenue however is from the 95% that gamble less than 5 figures, because there are many of those people and since they are mostly gambling with scared money, they usually are greedy and fearful and the casino makes a profit off them. Someone who bets in the 5 figure range usually has a net worth of 7 figures and they gamble without greed or fear and usually end up winning, if not they do it for fun. |

I was just looking for something related to these cards, in terms of price performance and capacity I am undecided
In my area I found some "offers" in the informal market (already used for mining, of course)
r9 290 4GB 65 $
rx 470 4 GB 75 $
R9 390x 8 GB 70 $
rx 570 8 GB 100 $
rx 470 8 GB 100 $
Some vendors say they have been used only for "games", come on ... I do not even think so. I would be encouraged to buy if any will go down for around $ 40 ...
they are usually double the price mentioned I suppose they will be desperate sale
In my area the pricing is pretty similiar. The RX 470 4GB resell value is very low probably because AMD made millions of those GPUs and almost all got bought by miners and now nobody wants them anymore. The 8GB always goes for more because it has more memory and in certain newer and more intensive games it performs better. It also performs a little faster with ETH mining due to the faster ram. The 290/390 pricing is similiar since they are power-hog type of GPUs and miners don't want them. And gamers might want them but due to the power issues they are noiser than say an RX 580 or some Nvidia 1070 GPU. |

In 2017 we had 30-40% pullbacks that were around 4-5 weeks or so. And it eventually engulfed those drops and hit a new ATH shortly after.
The reason why the pullbacks are so severe is mostly due to over-leverged longs. Basically a few days ago when we were at $13000 there was over $1.1 billion in open interest and today its only $700, so its a crazy amount of longs which were liquidated that lead to this severe drop which happened so quickly.
It looks like the $9200 area held, so see if we can test the $10000 area and close above it.

Its been years since I've actually run an actual Bitcoin core wallet but I remember a few years back I was getting freezing issues also. From what I've heard they might of been resolved by now.
I am not referring to the staking or mining with the core wallet but just running the wallet just to send and receive coins. The issue is mostly from not having enough system RAM and an SSD. The CPU doesn't really play a role, it only plays a role in the initial sync. But after you get it sync'd and if you got an old regular HDD and low amount of ram, it will freeze when it tries to open the wallet.
This is why most use online wallets or wallets like Electrum these days.

Not a fan of alts for gambling either. It WAS fun and seemed like a good idea at one time, now we all need to define digital money a lot better.
If you go to many of the gambling sites out there, people actually do place bets with coins other than Bitcoin. And right now its fairly cheap to send Bitcoin transactions, in the last 24 hours you could of sent a transaction with 1 sat/byte so basically a typical transaction could be as low as 250 sats if its 1 input and 2 outputs which is about 3 cents. However people still are using alts. Gambling sites are realizing this and this is why they are adding alts, not because the bitcoin network is expensive to transact but because there are people out there that own coins other than Bitcoin. So say there are 2 gambling sites, both featuring dice and say that one accepts Ripple and the other doesn't. Some gambler has a stack of XRP and doesn't own any Bitcoin, which site do you think they would deposit to? This way Stake would gain a customer. This is the customers that they are targetting for. Many people sold their BTC since it quadruppled since the beginning of the year but many are still holding alts which didn't move by much. |

There were 2 major price hikes in the history of bitcoin. One was the 2013 year and another was the 2017 year. Ethereum plays a major role in today's alt market since most of the shit coins are created out of ethereum network. 2013 weren't much affected with the shit coin losses since Ethereum was created only in late 2013 - early 2014. So people who came to know of the cryptocurrency market followed bitcoin and updated themselves with the tech in the later time. But the real problem started with the development of Ethereum and the formation of EEA. This was probably the reason which triggered various companies to learn a little bit of solidity code and create their coins out of thin air.
The event reached its peak by end of 2017 and probably people who came to know of cryptocurrency jumped onto alts in the verge of catching an earlier train. This fueled various companies and scammers to start their own coin. Once some of these companies collapsed, the 2017 newbies started realizing the real potential of bitcoin. This paved way for major selling in these shitcoins and the transfer of all their money to bitcoin.
Alts have the potential unless the start-ups don't scam and run away with investors money and similarly Ethereum is a good platform for bringing business into the blockchain if they are utilized in a proper way. The speculation of alts being the next bitcoin should come to an end and if that happens we would see the real potential coins which can solve the real world problems through blockchain cherishing over the period of time. People should become more educated and must have the capability of distinguishing a product based alt with a payment processing coin like btc.
I completely agree with this statement and it deserves a merit. Basically the complete dump of BTCUSD to $9850 which happened yesterday was mostly due to ETH in my opinion. I was watching the charts and when ETHBTC started breaking yearly support areas, all hell started to break lose. Most likely due to over-leveraged longs waiting for "alt season" there were 2 massive spikes in ETHBTC, which caused a dump in ETHUSD which caused a flash crash and this most likely contributed to the selling of BTCUSD. Now it seems to have stabilized however there might be more dumps if ETHBTC breaks the 0.02 ratio. |

Taking into account probability, you are better off starting the search from the middle of the range and spreading it outwards, however its not always the case.
2 Years ago when I tried to find #54 or #55, I tried it the same way and basically eventually gave up because ETH/ZEC mining was more profitable and when the key was finally found (by LBC if I recall) it was somewhere towards the end of the range, so I would of most likely never found it anyways.
Best would of been some type of pool for this, where if the key is found its equally distributed for all the shares submitted.

From what I recently learnt from a similar ancient GPU thread, https://bitcointalk.org/index.php?topic=1540107.0You can still mine ETH with the Hawaii GPUs however it won't work under Windows and/or with Claymore. You need to use software like SMos or PhoenixMiner and you will get the full 30MH/s that everybody got in 2016/2017. I didn't realise this and pretty much almost got rid of my R9 290, however most likely in the winter months will power them up again. |

Sometimes I play on yolodice. I noticed that yolodice supports some different cryptocurrencies, BTC ltc eth and doge.
I was thinking, why not xrp support? Xrp transactions are cheap and fast. Is it an upcoming feature? Are there other sites that support xrp to gamble?
It would also be nice to be able to exchange btc-xrp in yolodice plataform, as it already support somes exchange pairs
Hey there, according to Ethan in our chat the other day, he's not interested in adding any other coins at the moment, he said he's happy with the four we currently have, and would rather focus on new features in the future rather than more coins. This is just what he said, I suppose he could change his mind, but I think his interest in XRP is very very low. I think unless there are crazy bitcoin transaction fees like we had in Q4 2017, I don't think all gambling sites need to list many alts. Back in Q4 2017, it was very bad because I remember I had to pay $50 just to send 1 transaction which had 1 input and 2 outputs and it took probably 2-3 hours to confirm. Right now bitcoin seems to be going mainstream again with the Trump tweet and the Facebook crypto-coin and the transaction fees are very low. You can probably send a transaction at 5 sats/byte if done on the weekend. This was not possible back in 2017. I don't think its Segwit, I think its more of the transaction spamming that stopped and seems not to have an affect this time like it did in the last bull market. |

Its not only bitcoin or crypto markets that crash faster than they rise, its almost all markets especially the stock markets.
Look at the stock market back in 2007-2008 during the recession, it took years for the markets to hit those highs and only took around 1.5 years for all the profits to vanish.
Markets goes up slower than they go down mostly due to fear. Basically when the market is up 5% everybody is happy, when the markets are down 20% or so, people panic and everybody wants to get out at the same time. So there is massive selling pressure that accelerates everyday and everytually there is a recession.
Then it hits a low and the cycle repeats. This is generally how the rich and other institutions make their millions. Off the traders who sell out of fear not to lose money.
