I usually doesn't get convinced with cloud marketing but this site looks pretty ok to me. Already cloud mining industry is not healthy these days, the minimal withdraw fee is way high than I could earn in a month with minimum investment. Started feeling that mining is really Job of people who has got big fat wallets.
Just keep investing with the Bitcoin you get (after august 1st preferably) and then get enough to buy a nice amount of hashrate. I went about a year with only 20GHs and then, all of a sudden, I found I'd received about 0.17 BTC in that year that I could put into an S7 miner (4860 GHs). I then managed to collect another 0.07 BTC from somewhere and earn 0.08[brc] from my shares (too about 4 months though to even get that) and recently had 9800GHs (though I have just sold them due to august 1 st.
As an extra point, does anyone know why the S7 GHs have increased by nearly 400satoshi in a few days? I know 2900 was really low for them but I didn't expect it to go back up to 3300 so quickly!? |

I am developing a non profit project that uses a lot of forks (and bitcoin of course) - but's i can't decide what datatype use to store prices.
There are several ways to do this, but i have chosen two of them - to use BIGINTEGER, and store it as a STRING
1) - BIGINTEGER (in this case i keep pennie e.g. Satoshi) it's better to use in calculations - but i can't wrap my head around - how to properly take user input? What datatype should i use to use math operations in PHP, and what additional data i need to keep to convert on currency to another (i mean there are possibility that some forks can use more digits after point.)
2) STRING - just impossible to make any computations, before proper conversion. But it's much simper to keep - i mean you just can store the raw user's input
Can somebody share some ideas with me about this matter?
An inneficient way of doing this is by you just using strings for everything. There is only addition and subtraction that is required in this I presume, so you can easily just encorporate math in that way. Alternatively, you could try to use "Double" variable types or "Float" if php doesn't provide "double"s (doubles is with a desimal but is 64 bit floating point instead of 32 bit. I assum BIGINTEGER represents INT64, but you could as well just use regular integers as they should be 2 32 and you probably don't need much higher than that. |

Yes the best way is just to take your private key. Nothing more than that.
Anyways good luck keeping your coins till 2020
I don't have a sell plan really, maybe i switch a small amount to altcoins. If Bitcoin live i will have most of my stash left at 2020. I'd strongly recommend you don't go into altcoins based on how high Bitcoins value is becoming (at least without a strategy/bot to do it for you). Although, the altcoin price does seem to be fairly consistant on average with the Bitcoin price, (such as doge being always at 50 satoshi - when there are no manipulations of the market, pumps and dumps). |

I save my BTC to Paperwallet and Blockchain Web Wallet,what is your choices?
Yeah paperwallet/private key same thing. Don't lose private key, write it down or paperwallet, take care of your paper. Android for sure no. You can't know when they are going to make an update at app and god knows what will happen. I am ok with official blockchain website to be honest. Actually, the android wallet private keys can be recovered from the seed that is taken in a backup, so technically, you still control the private keys. It's jnot a perfectly clean operation (a few things need installing first) but it does grant access to private keys. |

Which wallet dont have fees and is safe? Also can you tell me which one is best.
There are fees applied to every wallet, that's how the confirmation process on transactions work. You can try either blockchain.info, electrum or bitcoin core. Blockchain.info is an online wallet, which has had quite a few issues in the past (technically) Bitcoin Core is the wallet software that is the main function of bitcoin and is the official client of it but it takes a fairly long time to fully syncronise and also takes up ~130GB in blockchain data (which needs downloading) - you can use -prune to get it down to 2GB though. Electrum.org is probably the best wallet for a software option, you can use that and it only takes a few MB to store everything in it. You also get a short seed that you can recover your entire wallet from with this choice (the others require either email/phone verification (blockchain.info) or backups to be taken (bitcoin). |

alright why would you need to mix anyway?
You may want to be anonymous online. OR you may be using a site that is restricted in your country or that you don't want tracing back to you, then you might want to use a mixer to hide what you are actually doing (whether it works or not is another question as it can still technically be detected where the coins travel to as mixers may make mistakes with the way they link their addresses - as all of their addresses have to be used to fund both themselves and their investers) |

The private keys are in the wallet.dat file right? I have multiple wallet backups! You cannot just save the priv. key and import where you want?
Even if you can't, In case of a fork your coin will be available in both chains, because you don't spend meanwhile.
So even for what I know you are safe, "like a cold wallet" if you don't spend any satoshi.
Okay, yes i have all Bitcoins on a wallet.dat, and have not touch them since 2012. So if i don't spend any coins i'm safe? Thanks! You should be fine as long as you have the private keys. Please make sure you have several backups of the wallet too. You can always export the private keys and use a lite wallet to manage them, even without being fully synced. Yes you are safe, even your backup copy are safe  Store a private key could be a good way to get a cold wallet. Isn't a cold wallet for definition (because now you have imported in your bitcoin core), but if your laptop is secure you can't risk anything by storing btc just in priv key. ps: Btc stored from 2012  ?! WOW If you dont want the brunt of the initial download of the blockchain of about 140GB you could try looking at alternative lighter clients such as Electrum (from electrum.org) which will still give you private keys and will still make you able to access both chains. |

found this on reddit...
It seems that BIP 91 has gained a bit of traction among miners and the warning in the title is now being displayed. This warning is triggered when more than 50 of the last 100 blocks has a version number which Bitcoin Core does not expect, and right now, that is being triggered by BIP 91 miners.
It's also interesting to note that some miners are signalling to orphan themselves. Antpool, BTC.com, and BTC.top are all signalling for BIP 91 with bit 4, but are not signalling for segwit on bit 1. This means that once BIP 91 activates, if they don't change their version number (and it seems that this is a manual process as most mining pools set the version number manually), they will be orphaning their own blocks under the BIP 91 rules.
Aha, that must be what is meant by this news message at the top of the forum: News: The warning which may be displayed by Bitcoin Core about unknown versions is related to BIP91, and can be safely ignored. Also, it's bip148 that we're awaiting the activation of (so maybe they're trying to adapt to that so it can be adopted) - or they might be hoping that the segwit chain sinks as it serves them to not connect to it is everyone doesn't. Also BTC.com and Antpool are owned by BitMainTech so maybe they're trying to combat segwit themselves. (Not sure if anyone else is though, be interesting to see how pools like Slush's pool, bitfury and viabtc deal with the change). |

WTF? is this because core v14.1 doesn't know about Segwit2x blocks? Should I be concerned?  Could you post the debug log of the time this warning came? Segwit won't be activated until August 1st (as far as I know). |

hey there i made a transaction to poloniex of 8 ETC and it didn't get out to polo wallet for 20 days till now some one told me to make another and all of them will be submitted to my polo ETC wallet and i did that with no change they are all in but no one out !!! i mailed the worst support all over the world and like usual they didn't reply  what shale i do now to get my ETC tokens ?? my transaction address : http://gastracker.io/addr/0x5d8e66c8c0288dc1f00b42beef2e47c287cdc4dfYou'll have to keep putting up with their support unless you want to take legal action against them and are able to. You could always try to sell the ETC for Bitcoin and then take out the bitcoin to another exchange to see if that works at getting them out. What did their support say exactly? |

Hi,
1. A couple of years ago I had a wallet with a few BTC (left) in it; I quit the bitcoin environemt after I fell in the LTC gear scam. The wallet was working perfectly, i believe it was version 0.9.1 then.
2. Lately I decided to get back in crypto (essentially driven by the Etherum concept), i downloaded Bitcoin Core wallet 0.14.2 and got it to install on a dedicated hard disk by itself (as I knew the size of the block chain will be considerable, 132GB).
3. After I installed Bitcoin Core wallet, and before starting it, i did the following:
3.1. I went into the .conf file and put a password
3.2. I coped my safely stored wallet.dat file in the folder.
4. Bitcoin Core started downloading the block chain; the process took 3 full days. However, during the download process my PC went to sleep and would not return from sleep so I had to force shutdown. No symptoms appeared as the download of the block chain continued.
5. Once the download of the block chain was 100% compelted, I got an error stating that the program cannot read from the database, and that I should shutdown and contact support.
I tried to download and tun PYwallet but I read that there is a for somewhere that sends the privaste keys to a bieber.x host, so I did not run nor use PYwallet and decided to come here and ask for your help what can I do to get the wallet running correctly as I don't mind running a full Bitcoin Core wallet to help the network a bit if it does.
Alternatively, would the same wallet.dat work with a lighter version of the wallet?
If you want a lighter wallet, I'd suggest electrum.org. However, you'd have to import private keys which is costly in transaction fees (but not too costly if you have more than ~0.01 BTC and few input transactions). |

We're not going to get 50%.
Maybe 10%. But, once those blocks have been mined (if they have) then the hashrate will fully adjust.
The majority of blocks are mined under the average also (most between 8 and 9 minutes because there are blocks that take hours to mine - one took an hour and a half around 6 months ago).
If the BIP 148 fork has 10% of the pre-fork hash rate, then each block will take 100 minutes on average to mine. It will be that way for 10 - 20 weeks followed by 5 weeks of 25 minute blocks. But once that period is over then it'll be back to 10 minutes. (Although I'm not sure how many miners are still using builds that won't support segwit - I think that's everything before 11 isn't it)? |

I have a script which creates many addresses in one wallet and can mix my coins between them. It's the safest way, 'cause coins always with you and you know that nobody have mix logs. If you're programmer you can write such script for yourself. It's not hard
All you are doing is paying fees to move your coins around addresses inside your wallet. You are not "mixing" anything. As soon as you attempt to create a transaction that requires more coins than you have in one address, your wallet is going to add in extra input(s) and then those addresses are forever linked as being controlled by the same person/entity. Additionally, it is highly likely that funding of your multiple addresses all comes from common parent addresses/transactions... which would probably enable someone to link all those addresses without you spending the coins. A true mixer will enable you to have multiple addresses that are in no way linked to one another... and obscure the source of those coins. Ahhh. I forgot about public keys as well when bitcoins get sent. The new HD version of bitcoin core can therefore link all of your addresses together and anything else already does it to it's fairly useless to attempt it. |

Okay the thing is I have BTC wallet with my ID and other information, so sending btc to some darknet website could cause a problem. The question is do I have to use btc mixer to avoid information leakage or I could create .onion free wallet and send from my original to free wallet and then to website wallet? Will It be safe? Thanks  I have a script which creates many addresses in one wallet and can mix my coins between them. It's the safest way, 'cause coins always with you and you know that nobody have mix logs. If you're programmer you can write such script for yourself. It's not hard No one denies it's not hard. The point is that that coin can still technically be traced back to you more easily. The idea with a bitcoin mixer is there is a reserve pool of say 1000 BTC. When you send them 100 BTC to one of their addresses, a transaction springs up to that value (100 BTC - tx fee and handling fee) from a different address. These coins never touch, their inputs never meet. The coins you deposit is then recycled back into the system and is used again to process another transaction and build up a large network of transactions that are difficult to determine the initial owner of each coin (it is still possible however but takes a much more complex script to match the similar amounts togther). |

Hello there, please i help. Please Pardon my in experience.
Am planning on a project but will like to run an ICO maybe after like 3 - 4 Months after launch, but i really want to be sure of what am about to do.
My project simply receives payment via Bitcoin, and may be we will add ETH later.
But i know its possible to offer to sell your own token but it need to be useable on the site itself so i read.
Now am proposing to Develop a token on Etherum, and connect this token to the site for funding an account. I also read that it's possible for this token to be traded. So owners of the token can either trade it on exchange or use it on the site
I hope am correct to this extent.
My main worry now is.
If for example 200,000 worth of token is sold for $0.01 each, it means you would need 100value of the token to buy something worth $1 at the present token value.
How will the value increase? Does it mean that we will be giving back what was sold in the token? If not, how will the value increase via exchange?
Values of your token will be set by supply-and-demand limits. If there is a greater demand on the coin then the supply, the coin will go up in value. If there is agerater suppy, the inverse will happen and the coin will start to decrease in value. Therefore, your coin/tokens value will be set by the people using the exchange itself and placing Buy/Sell orders on it. Thanks so much for responding But what will determine the first exchange rate initially before the forces of demand and supply takes place? The price you choose to set it at. Unless you want to try to giveaway some of the tokens first. Such as offering a token for 1 satoshi each and 1000 tokens free when a user signs up or omethinglike that. You have to work out how much you think your token is worth first and how much demand there will be on the token and your site in general. Thanks so much. But i was actually referring to how much initially the token will worth at the exchange sites where these tokens can be exchanged to other crypto coins If i sell the 1 token value at $0.01 for example, will this be the same value at the exchange platform before the force of demand and supply takes place? Thanks. It'll be what users wish to sell it at. If you limit the number that can be bought at $0.01 then when that runs out the value of the tokens may spike a little. But it depends on what the token is and how it works. Also, you might not be able to use other exchanges unless it is decentralised in the way altcoins are as you are the one controlling all of these tokens and can technically recall them at any point and make them worthless. |

how could we trust you , any proof ?
He's not going to pay anyway, but you can share your bitcoin address with as many people as you want as they can't take your money anyway. |

The difficulty dynamically changes based on the difficulty. It does take quite a few blocks for the difficulty to change but it will eventually change and go much lower. What goes up can come down and if we had stuck to the difficulty that satoshi used to mine his first block, we could gt a block by asics now in a fraction of a second!
1008 blocks in average.
It could be months until the first change occurs. Also, there is a very important detail that might be overlooked. That is that the the difficulty can change by a maximum factor of 4. The difficulty may not immediately adjust to the new hash rate. Let's look at some scenarios: The worst case is if the difficulty adjustment happens at the same time as the fork. | New Hash Rate | | Difficulty Behavior | | 5% | | 40 weeks of 200 minute blocks, 10 weeks of 50 minute blocks, 2.5 weeks of 12.5 minute blocks | | 25% | | 8 weeks of 40 minute blocks | | 50% | | 4 weeks of 20 minute blocks |
The best case is if the difficulty adjustment happens half way through the difficulty period. | New Hash Rate | | Difficulty Behavior | | 5% | | 20 weeks of 200 minute blocks, 10 weeks of 50 minute blocks, 2.5 weeks of 12.5 minute blocks | | 25% | | 4 weeks of 40 minute blocks | | 50% | | 2 weeks of 20 minute blocks |
We're not going to get 50%. Maybe 10%. But, once those blocks have been mined (if they have) then the hashrate will fully adjust. The majority of blocks are mined under the average also (most between 8 and 9 minutes because there are blocks that take hours to mine - one took an hour and a half around 6 months ago). |

And that could be with bitcoin mixer aswell (stealing)? Maybe you can recommend one thats not scamming? The one in my signature or the one in the first signature of the first person who posted here are both fairly trustworthy (or should be). |

It can work but I'm really recommending you to just go for a mixer as the safest route. If you were to send it to a wallet, the wallet might just send directly from the receiving address to a destination address. Even if its a service and they send it to their hot wallet first, logs would be kept by the service.
I'm not saying that mixer will not keep logs but you have a better chance with them. Plus, the mixer would erase any associations of the previous transactions.
Thanks mate Yes, and you still have to pay fees to send it to another wallet. Even if the wallet doesn't keep logs (because it's a .onion one) it'll note the initial sending address and may just steal your coins as you don't know who is running it. |
