Some pepole say i need to use CUDA worker for INVIDIA Right now im useing OpenCL worker What shuld i use and how do i use CUDA Thx for you help i really love you guys  This is cudaminer ( https://bitcointalk.org/index.php?topic=167229.0). It utilizes the cuda cores found in nvidia GPU more efficiently than OPENCL(optimized for AMD). The performance increase is significant but would still be slower than a ASIC. Unzip the file and read the readme.txt for the instructions on the usage. |

Why would you want to go through so much trouble to get a bit of Bitcoin. If you have a Bitcoin ATM near you, use it, the exchange is very fast and you wouldnt need to wait so long, just a driver license to verify, insert cash and done.

This should be at the meta section. The searching function was turned off a few days ago after downtime (due to failed RAID harddrives) for theymos to regenerate the search index. Use google to search instead. (insert keyword here) site:bitcointalk.org |

Someone has probably already mentioned this, but online wallets are FAR less secure than offline wallets. I use Multibit as my offline
wallet. Sometimes I keep some Bitcoin on Bter.com for the daily interest it earns, but most of it I keep offline.
It all boils down to the security management of the online wallet. Opensourced Online wallets such as Blockchain.info allows user to export their private key, enable two factor authentication and the private key is encrypted on their server. Sure, offline wallet is even more secure but blockchain.info is already secure for typical users. |

A few satoshi, CPU mining is a thing of the past. GPU took over CPU mining late in the 2010. ASIC took over GPU at around 2013, the smallest ASIC miner, USB block erupter can mine Bitcoin more efficiently in terms of power consumption and space requirements. You can try mining GPU and ASIC resistant coins but there is no guarantee that the price will crash and you would lose your profits.

Everyone have different preference when we come to choosing a exchange for the price. Most of us would either select the largest exchange or use preev.com which calculates the average price over a few exchanges. The price is locked before the transaction, you have to tell him how much he has to send. The amount of BTC would just be the amount of BTC when you agreed on. The amount lost is probably due to transaction fees, usually 0.0001.
Coinbase would not know if you are doing a gambling transaction unless the transaction originate from a well known online gambling address. Even so, they dont ban you. If you happen to send the amount to a onchain dice site, you will not receive your winnings since coinbase sends it from a different address and they wouldnt have ways to verify that you sent it and credit you.
There are loads of people without coinbase account, you can either transfer coins offchain from different accounts or give them your address and your bitcoins will be transferred correctly regardless of wallet type.

it is unsafe as it is a shared wallet.
Please explain. Shared wallets means that the private key is stored on the server. If the entire server gets hack or go down, you would not have access to your coins anymore. Desktop and cold wallets(including blockchain.info) however, allows you to have control over your private key and is open sourced which is safer than online shared wallets. I believe Coinbase stores most of the coins offline, but I could be wrong. I'll look into it. True that, but they do have a possiblity of running away with your coins or blame them on a 'hack'. You would not have any ability to check on them as your private key is not with you. |

Ok thx,
But is it normal that it's more than 8 hours on estimated reward and it's so unstable?
Yes, the last block was found yesterday, 14 hours ago. It really all depends on the luck of the pool, the more blocks they find the more often the rewards but the rewards would be lower and vice versa. I guess the unstability is due to your GPU and other miners submitting shares resulting in less payout per share. However, the GPU will also submit share, therefore the estimated rewards will go back to somewhere near the original amount. |

Your expected reward is the estimated reward. For it to turn into unconfirmed rewards, a block has to be mined by slush pool. For unconfirmed to become confirmed rewards, you have to wait till 100 blocks are solved ~ roughly 3/4 of a day. Your setup is going on fine, you can see the shares on the page and the hashrate there. However, GTX 660 is a very slow miner, if you want profit, go for a cheap ASIC. Even a USB block erupter beats it by a few times. |

I created a coinbase account but didn't sign the agreement and didn't put my name in it yet. I will do that soon. I wanted to know once I do that and my bank account is verified... assuming i don't buy any bitcoins through coinbase.com which is the 1 percent fee and 15 cent fee each time, if i were to receive bitcoin from another user and buying it from them... would that be fine? Im on a forum where ppl trade poker funds for bitcoin so i wanted to know if i receive bitcoin from them, am i suppose to have them send it to my coinbase account or my blockchain account? I might do the multibit or electrum wallet but for now i think im just going to keep things simple and use blockchain. Note... any bitcoins i receive i either will be sending it to my coinbase account then to my bank of america or will be sending it directly to gambling sites. So if thats the case... then i obviously have them bitcoin to my blockchain or multibit wallet as oppose to coinbase then right? Im also a bit confused but i assume u can send/receive bitcoin from others with coinbase?
If you want to directly exchange the bitcoin to fiat, use the address provided by coinbase. If you want to sell them your poker chip, you can use any. Coinbase also function as a online wallet although it is unsafe as it is a shared wallet. Also try to avoid using blockchain.info, they have plenty of security issue recently. |

it can not be due to variance??? Who's turning on new miners? New Chinese mining farm(s)? Don't they know btc price is in the dumps???
It may be possible that people mining other sha256 altcoin are changing their miners back to Bitcoin. It may also be the luck, the network happens to be mining more blocks at a faster rate due to the luck or perhaps mining companies testing their new ASICS. The network total mining hashrate is only for estimation only, it is not 100% accurate as no one can count the machine's hashrates accurately. |

That only apply to newly mined coins. Those coins are not newly generated so this doesn't apply. Any input that is not newly mined with 1 confirmation is considered to be matured. The main factor is the priority, it must be higher than 57,600,000 to have a high chance of confirmation. The formula for calculating priority is priority = sum(input_value_in_base_units * input_age)/size_in_bytes Where input age is coin age, 1BTC left untouched for one day has a coin age of 1 the amount of confirmation. |

Does anyone know a legit operator that offers this service?
I know fastcash4bitcoin.com can fund a Payoneer card via Bank Transfer (ACH) which would be great, but Payoneer limits this service to only its US card holders. Is there any websites like fastcash or bitinstant that can fund a Payoneer using Visa or Mastercard (this is the other funding option Payoneers allows)
If you want to fund the VISA directly, use virwox or btc-e to withdraw. For wire transfer, try using btc-e or kraken, both of them have a good reputation and have relatively low fees. Actually I have funds in my payoneer account I have its debit card. I want to convert the funds to bitcoins. Use virwox or currency exchange section. The fees may be high due to the risk of chargeback associated with it. Always use escrow before trading at the currency exchange section unless the person is very trusted. |

Do take note that some wallet service actually delays your bitcoin transaction, the invoice may actually expire before the system receives your bitcoin. A good idea would be to send the bitcoin first to desktop wallets(multibit,electrum,bitcoin core) or online wallet(blockchain.info) and make a payment from the desktop/online wallet.

This would be huge if McDonalds did start accepting btc but it's not gonna happen. I don't think bitcoin is even used enough right now for McD's to bother with it though I hope I;m very wrong. If McDonalds starts accepting bitcoins
Ronald McDonald will be a "cryptoclown"
LOL
Not sure if there is a pun that I am missing there. You're not missing anything, it's just a shit joke lol. Not really, Bitcoin is pretty popular among people right now. It wouldn't hurt for them to integrate Bitpay/any other POS solutions into the system. They can pretty much reduce fees for credit card transactions, saving loads of money. With bitpay, it can be nearly as fast as using cash or credit cards. |

How much is the usual fee?
Who pays for it?
The usual fee is around 1%, there are a few trusted escrow who does free escrow. It all depends on which service you trust, the fees vary based on their quality of service. You can negotiate with your buyer and choose who pay the fees. |
