none of the exchanges are to be trusted, to be honest. coinbase is not a real exchange, and is probably the most trustworthy of the lot. Bitfinex, to be honest, is very shady IMO, and now that Bistamp liquidity has been removed from its order books, it is a very illiquid exchange. to just buy (and not trade) Bitstamp is worth looking into.
I haven't follow bitstamp news recently. Have anything bad happened to it?  well, some people have been complaining that they have been getting increasingly invasive with KYC procedures. some have suggested that this may be a tactic to stall on withdrawals (suggesting insolvency), but that seems unlikely to me. KYC/AML is a legitimate "hoop" to have to jump through. If, after you have jumped through this hoop you still expericne delays then you may have other issues. |

Thanks for the list. IMO, one slight problem of it is that it puts John K in first place, without mentioning he has a history of disappearing while holding escrows for months... You should still use common sense when dealing with escrow. Before blindly accepting someone for escrow search their user name to check for scam accusations. |

Most paper wallets have two QR codes, one for the private key and one for the public key.
You can scan the public key QR code to get the public key saved to your clipboard and check blockchain.info
Another option is to use a "watch-only" address with your blockchain.info wallet.

I know a few people from this thread wanted to know when our move to new servers were complete. I can say that it is completed and we passed all our internal test to make sure the data is correct. The blockchain we hold I call it A1 because we examined all the data after the move.
Also we will not be moving any more! We will start growing horizontally now. It only took us a couple months of production to go from a little couple of servers, to now a big boy server, to handle our loads.
Looks like you are now on Atlantic Metro Communications VPS. Why are not u giving a try to Amazon AWS or Google App Engine ? Are not they better for this kind of a large scale operation ? We are not on any VPS system, we are on a dedicated server provided by http://www.bitronictech.net/aff.php?aff=061. Why we choose them over AWS or APP engine, well a couple reason. One is that I actually worked for a datacenter at my college, before I got into bitcoins so I actually do tweak some very low level settings. Every ounce of power you can squeeze of a system, makes my project that much better than the next one. This rules out google app engine. Two I want to support the bitcoin eco-system. If you read some of my early post I actually called for someone to start a hosting PaaS for bitcoin. It would sky rocket, and you wouldn't have any of the issues you have now with hacked AWS accounts. My startup has paid everything so far in bitcoin. Making it so I never have to get a bank account for my business! Trust me this some powerful hardware, I know what I am doing and the site has yet to be down excluding today when I had to move the huge blockchain database. Which as you can see went as planned. Really proud to know this buddy. I wish all bitcoin entrepreneurs have this ideology. Thank you, bitcoin just makes business so easy in this global era. Yep, but finding counterparty to accept bitcoin is sometimes a pain. There are a fair number of ways you can pay for things in bitcoin in non-traditional ways. You can use gyft (for consumers), get vendors to use coinbase or bitpay for your specific transaction. |

I'm just getting started with bitcoins after someone at my site introduced me to them. I tried mining but my computer is to weak.So I started investing I've made aprox. .0006 BTC but I've only been doing it for a week or two. So what I'm asking is do y'all have any advice for me.
That sounds like a lot to have earned if you have been CPU mining for two weeks. |

Have purchased/sold ~35GH worth of cloud mining on ghash.io over the past several months and aside from the occassional pool-related issue(s) never had any problems. *Did I earn any real profit? Nope, matter of fact I ended up losing money but it was a valuable learning experience  Cloud mining will almost never earn you a profit. Cex has put a stop to this, but you used to be able to buy GH/s then place an order to sell right away, and you would earn whatever it mined until it sold (they now charge a trading fee) |

You previously said that eligius lost ~400 BTC, based on $571 for 1 BTC that comes out to ~$228,400 that was stolen. Your largest mining address lost ~$14,850 from the selfish miner. If you look at your number 5 mining address they only lost ~$3,300 from the selfish miner. The point is that the amounts of individual miners are relatively small and probably would not be worth hiring an attorney over, also attorneys would probably want to be paid by the hour for a case with that much is dispute. If you were to hire an attorney to bring a case trying to recover the entire $228,400 (400 BTC) then there would be a better chance that an attorney would work on a contingent basis (agree to only get paid if they win and the payment would be taken out of the settlement/judgment). Probably right. Which would mean it'd have to be a class-action case (if there even is such a thing in China). As far as I know, nobody ever wins in class-action lawsuits...  The attorneys usually win in class actions cases. Are you located in China? Is the selfish miner located in China? I am not sure where the appropriate venue for such a lawsuit would be. If you are located in the US and the selfish miner is located in China then federal court would be appropriate as there is a dispute over international commerce. You would need to prove that the "damages" were done in the US. If the pool is in the US and the pool was the entity that was damaged then this should be clear. If it is determined that the individual miners were damaged then this is much less clear. If a class action lawsuit were to be filed then "class members" located in the US could be included and the suit would be filed in federal court. The definition of located complicates things significantly, does it mean the equipment is located there, does it mean the "owners" of the BTC addresses live there, does it mean they are US citizens/residents? I honestly do not know the answer to the question. One thing I noticed lacking on your website is something that says what laws would be followed in the event of a dispute or what court cases would be held in (what state/district). If there is zero relationship between the pool and the miners this may be a non-issue. 2 - Individual miners may not have standing to sue the selfish miner. In a civil case (involving money/damages) you must prove that damages be caused, but also that he damages were against you. There is clearly a relationship between the miners and the pool (the miners provide work for the pool and in exchange for each unit of work the pool provides a maximum amount of payment, if payment is less then the maximum then when the pool can afford to pay more then the maximum the units that got paid less get paid more). The relationship between miners at the pool are not as clear. I am not an attorney, but I think a likely ruling would be if a miner tried to sue another miner at the same pool, the judge would say that their "beef" is with the pool operator, not the selfish miner. On the other hand if the pool operator were to sue a miner the damages are more clear, as the miner did not provide the work, the miner said they provided the work, and the pool operator paid for the work that was not done. There is clearly a fraud here. Pools don't pay miners for work, merely coordinate cooperation between miners who pay each other. This is especially clear-cut on Eligius, where most of the funds never pass through the pool operator's hands. That may be how it is on a logistics standpoint, but is that how it is in the eyes of the law? If you were BTC Guild or ghash I would say defiantly no, as both of those pools have block rewards (and tx fees) paid to the "pool" wallet, and the BTC is then eventually transferred to miners' wallets via automatic payouts. Eligius is very different in that it pays the block rewards (and tx fees) directly to miners via a TX in the found block. Someone could argue what you are saying but they could also argue that since the pool determines who gets paid how much via the payout cue (this being embedded into the header of work provided by the pool - I think this is how it works) that the pool does really control the found blocks. Even a attorney could likely not answer this question with certainty, as I don't think this kind of dispute has been litigated before. The only person who can answer would be the judge that hears the case (and any appellate panel of judges that hear any appeals). I do question what this person's motive would be. In theory he paid good money for this equipment. As far as I can tell he has done this to multiple pools. Do you think it would be possible to modify mining software so that only the stratum shares are sent back to the pool with the correct header, but the other shares could use a different header (one that pay out to another address)? Do you have a way to determine when he withheld a block from the pool? If so can you compare that to other blocks found around that time, is there any consistency as to who found the blocks? I know that it has previously been determined that you cannot modify block headers to make a found block payout to your own address as the hash would be invalid, but someone who has the resources to have millions of dollars worth of mining equipment might have the resources to make this happen. |

What would happen if all bitcoin miners unionised and decided to go on strike? Most likely it's highly unlikely to mobilise such a global union but hypothetically what would happen if one day the mining stopped?
They would have no reason to do this. Miners have invested good money into their machines and taking their machines "offline" would mean that their capital would not be used and would be deprecating. |

I would be interested in buying 1 CALL contract (covering 100 BTC) at DEC 31 2014 expiry with strike price $500.
Accepting offers.
A CALL for that amount expiring today would have approximately 100 * (650-500) = $15,000 in intrinsic value. Add 205 days of time value premium, where historically the underlier has ranged from $400 to $1000 over a similar period of time, a standard deviation of ~50% of log returns. And we can estimate that today this Call option is worth a total of approximately $60,000, but any writer in their correct mind, would need to add on a charge of 5 to 10%, in order to expect a profit. You need to have a liquid options market for options trading to really be effective. With enough buyers/sellers in a market then individual participants will have their own motives (speculation, hedging) that can help set prices. |

Stay away from those "arbitrage" sites. All of them are scams that steal your bitcoins!
This. Also if a site could successfully execute arbitrage then they would simply use their own funds. |

Coinbase allows you to buy up to 50 BTC at a time (per day)

What exchange allows this?
If any such exchanges do this, whats the best rate?
I need some BTC as im wanting to invest in other altcoins.
You can use https://coin.mx/They have very low buy limits as they are at a high risk of fraud. I think there are a few other sites that will sell via credit card but the prices are much higher then the exchanges as they are taking a lot of risk to be scammed. Coinbase allows you to link you bank account and use your credit card as a backup if your bank transfer is returned NSF |

WHat's the best way to trade bitcoins in China using my Chinese bank account?
There are a few BTC ATMs located in china. Depending on where in China you live you can use one of them. |

Part of the problem with arbitrage is that others will be doing it, hence the current profit margin that can be gained from doing so will already be taken advantage of.
The free market is very adept at handling price mis-matches, especially if there is real money to be made.
If you're going to arbitrage, I'd stick with exchanges with fast turnarounds and really low fees, like 0.2% or even less.
But of course, with Vircurex just freezing accounts, that doesn't help either. There's no regulation out there, so nothing prevents exchanges from just outright stealing your money and then claim some bs like "fraud prevention."
Even if you have low fees, you still have the issue of having to wait for 3 or 6 confirmations to have your funds available at the other exchange and risk the price moving against you in that time. |

Hello,
Is there any Silk road site right now on the internet which is real and not scam? If so can you help me register and use it? Never used tor browser before, is there any specific thing to know when using Tor? I will appreciate any help.
Thanks!
PS also not sure if here is the place to ask...
There are loads of them.... see this list: http://www.deepdotweb.com/2013/10/28/updated-llist-of-hidden-marketplaces-tor-i2p/Hahahaha! Thanks for the link and for the trouble to register an account just to give us the link! Hats off to you sir! Watch out for two things: 1) Getting scammed. 2) Getting arrested. +2 lol It is highly advisable not to buy illegal drugs period. Trying to do things like this is what gives bitcoin a bad name. |

I don't understand why people don't just buy from trusted exchanges instead of going to the trouble to meet someone IRL with not only a chance of getting scammed but paying a lot more for the BTC then they're worth (at time of purchase).
People want to make trades in an uncentralized fashion |
|
|
|
Is there any service where I can just get it in like less than 30 minutes?
If you live and/or work close to a BTC ATM then you can buy bitcoin pretty much instantly. Otherwise you are not going to be able to purchase bitcoin in less then 30 minutes. |

|

There would be easily, I googled some sites, but they tuned to be scam.
It needs just to be taken serious and to study the market, nothing else.
Sites will easily be scammed if they were to do this as selling via a cell phone is the same as selling via a credit card. |

I was thinking to buy some bitcoins but i have few concerns since using Localbitcoin is i am not sure really the right way to go. I did hear from few friends which they warned me that feds are trying to use sites like that to catch people selling their bitcoin in $5K or more in person and then they would accuse you of laundering money. (i dont want to go into jail because of bitcoins)
What do you think about this things? I did hear some sort of stories occur in past. It might be an issue to be aware off or not?
Just keep the amount of bitcoin you will buy or sell limited to less then 4 figures and you will be fine. If you have repeat buyers just make sure they are spreading out their transactions enough so that it could not be considered "structuring" |
