It is readjusted every 2016 blocks based on the timing between each blocks for the last 2016 blocks and attempt to adjust the timing to 10 minutes. It is possible for the difficulty to go down if a lot of miners get shut down due to the profitability or other factors. If the miners begin to ship or a large farm comes online, the difficulty would rise much higher than normal.

...that it's impossible to create counterfeit coins. Wrong. Care to elaborate? AFAIK, the only way to create 'counterfeit' coins is to double spend. Risk of double spending can be reduced if you take the appropriate measures. Most merchants require at least one confirmation to confirm the purchase. To successfully double spend a transaction with 6 confirmations, you would need to have at least 51% of the network's hashrate. If any pool goes near 51%, most of the community would start leaving the pool unless the pool takes appropriate measures. |

is there anyway to mark those btc as "stolen"?
Bitcoin protocol don't mark Bitcoins. Even if they are marked, they can easily be mixed using a mixing service and no one would know they are stolen. IP address are useless as they can be private VPN or proxy. Check for malwares and always enable 2 factor authentication. Make sure the address bar matches bitfinex's address. |

Hi everyone,
Some time ago I bought 100 BTC (+70.000$), most of them I lose through hackers, mtgox, investing in HYIP, getting scammed by cloudbet... Now I have a bit less than 10 btc left (sadly worth nothing in compare to my initial investment). I'm used to keep them at exchanges like kraken and justcoin (which closed recently), then I discovered bitfinex and now I'm offering swaps there, hoping to maybe get back an extra bitcoin within a year. But I'm wondering how safe it is to keep my bitcoins there and offer swaps? I can make some profit there (and technically it should work as long as the owners don't run away or something went wrong on the website) but I'm also a bit affraid of losing everything. It also has some advantages, sometimes I really want to make some bets and recently I did it a lot bringing me from less than 3 to over 9 BTC. But that's mostly because of luck and maybe that could precent me losing my bitcoins that way because I never have access to my bitcoins immediately unless I change the autorenew settings in the website and wait for a few weeks. So what would be the best way to store my bitcoins? Going for the profit and let the bitcoins earn intrest on bitfinex or what do you think? My mail is safe now through 2FA if that would matter. If I deposit around 10 btc there I could earn around 2 mBTC every day by just offering swaps.
Bitfinex is just like any other Bitcoin exchange, they have the potential of running away with your funds. It is never safe to entrust your bitcoins to someone else. They can either claim to get hacked or just simply shut it down and run away. Remember this rule, the house always wins. Due to the house edge, you can't win in the long run so do not gamble more than you can afford to lose. Store majority of your bitcoins in your cold storage and put a few on your online wallet for day use. |

I've just invest to bitcoin, so I have question: can I transfer direct money from Paypal to coinbase? using paypal to buy bitcoin and receive money when sell its?
AFAIK, you need a US bank account to transfer money to coinbase. Coinbase don't accept paypal deposits or withdrawals due to the fact that they are easily reversible. Try virwox or the currency exchange section. |

Signature campaigns is probably one of the best ways to earn Bitcoin. Alternatives are faucets, or giveaways in the games and round section. I would recommend you to use the faucet at primedice, they have good faucet payout. If you have skills or knowledge in programming, offer your service at the service section to help people to code their program.

I suggest you not to invest in cloud mining because many cloud mining services are nothing but HYIPs.
Anyway, even if they are legit, the ROI takes too long to be reached.
I agree, however even if the cloud mining company is not a ponzi/hyip most cloud mining contracts will need to have the difficulty rise unrealistically slow in order to potentially ROI period. That is why some of them allow you to trade the contracts. This feature also gives you a way to bail out should you need to. CEX.io's maintenance fees is much higher than the payout so you would get negative payouts, the cloudmining there is already unrealistic. On the otherhand, if you are looking to profit, the best way is to trade. However, without sufficient experience and funds, you would most likely not profit. Trading is like gambling, you have the potential to lose in the long run unless you are experienced. LTCGEAR.com or pbmining, but pbmining is anonymous, so LTCgear.com is the safest, roi in 10 to 14 weeks. LTCGear seems to be quite new, I haven't seen any proof of ASICs actually mining. I wouldn't regard them as the safest as they could potentially run away once they have gained a lot of deposits. Also, you cannot sell the hashrate whenever you want to. |

Antminers is a very good mchinesto mine with. YOu can still reach roi if you have cheap electricity.
There are a lot of factors affecting ROI, if they decide to delay shipment, you would have less chances of getting ROI. You need to have good cooling equipments and space, if the difficulty increases very fast, the chances of you ROI would be reduced. |

You are going to need a vpn, I believe pd3 do not work via tor.
PD3 does work via Tor but be sure that you are using the latest version as you have the potential of getting hacked by POODLE vulnerability. VPN is infact more secure than Tor. |

Online wallet like blockchain.info
Currently, there is only one wallet like blockchain.info .  ~~MZ~~ No there are many online wallets but blockchain.info is the only trusted one and the longest running.....online wallets can be found inside coinbase too which is used by many just for hot wallets and not actually trading. I think you misinterpreted it, wallets like blockchain.info do not store the user's private key and allow the user's to control their own private key instead of sending them all to one shared wallet like coinbase, giving the user no control over their coins as they have no private key. |

Sorry man!
I need a VPS but not with your trust rating.
but i accepted escrow Even with an escrow, you have the potential of getting a refund or resetting your VPS password after getting payment. |

hello anyone tell how to mine bitcoin freely,i still did not understand and is this possible or not?
You can still mine using CPU and GPU but they cannot make profits. Mining is basically for big companies and people who invest millions into ASICs. For a small home miner, it is impossible to mine and get profit since the hashrate and difficulty is rising very fast. I wouldn't recommend you to mine since GPU or CPU as they are too slow compared to ASICs and ASICs may not always ship on time, by the time you recieve them, they wouldn't be profitable already. You can try cloudmining although risk are involved as the operator may run off. Try GAWminer, their rates are pretty reasonable and have proof of mining actually going on. |

Took me four full days to download the BTC blockchain.
For newcomers and widespread adoption that isnt to hot actually..
I'm surprised it wasn't longer than that if you downloaded it recently, personally. I downloaded the Blockchain back in June of last year and it took me about 3 full days, and that was when it was "only" 9 GB. I'm having to do some troubleshooting stuff to recover my computer from a virus I had earlier, enough that it may end up wiping my drive knowing how messed up Windows is. Is the blockchain BitTorrent still being maintained? I'm just wondering because I need to know if I need to make a backup of the blockchain on my hard drive. You can upgrade your computer to SSD if possible. The read and write speeds are significantly faster. The Blockchain snapshot on the BitTorrent is still available but you may need sometime for it to sync as it isn't the newest snapshot. whats a blockchain bittorrent?? i just started syncing and its so slow. is that something to speed up sync? It is basically the Bitcoin Blockchain file on torrent. By downloading the blockchain using Torrent and put in your bitcoin datafolder, you can speed up sync. This process skips the CPU verification part and the problems of having slow peers by connecting to lots of peer. Take note that the first start up will still take sometime as the client still needs to verify the blocks. Since the blockchain file on torrent was created sometime ago, you still have to synchronize with the network for sometime. Here's the full tutorial https://github.com/bitcoin/bitcoin/blob/master/doc/bootstrap.md |

Is i tpossible as of i knew that you need to give your address and code so that they can send you money..definitely hacking you account!!carefull in sign on in your account...but come to think of it..your a lucky one..receiving such amount...cheers! BTCThey can get your address from any search engines or blockchain. To be able to spend your coins, they need your private key which they will not know unless you tell them or you have malware on your computer. They only have your address. |

Tor is pretty safe as long as you download all the updates. The latest Tor update disabled SSL3 and it is not possible to MITM attack with the newest version.
I don't know Tor enough to be criticising it, but the whole idea seems rather unsafe. I don't feel comfortable with typing any passwords in it. Traffic coming out of tor exit nodes are unencrypted. Rogue exit nodes can potential capture unencrypted information transmitted using HTTP instead of HTTPS. Alternatively, vulnerbilities in HTTPS can allow those exit nodes to see encrypted information and capture your passwords. |
