As far as I know, you can't.


CPU/GPU mining is over. You have to buy ASICs now and even with that, your ROI will be pretty bad. You could get some if you mine altcoins, but be careful when choosing. There are many worthless coins and pump-and-dump coins.


Many sites which offer cloud mining are ponzis and scams. You should check *every* details before investing. Checking their total hashrate against total hashrate they sell can to some extent see if they are legit or not.

There is a time limit if that's what you are asking.



Yes. Do note that if you post in two activity periods (1 period = 14 days), you can get a maximum of 28 activity in a day or two. See https://bitcointalk.org/index.php?topic=582736.0 for activity period timings.

Reusing addresses is considered not safe too if you are using a bad wallet. When you send Bitcoin from A to B and change is send to C, other than you, nobody will know C is your address. They can only speculate that it might be a "change" address. If you send Bitcoin frequently, using different addresses will make tracking your transactions more harder. If you only use one address, everybody can see all the transactions you have ever made which is pretty bad IMO.

If you are using https://github.com/iancoleman/bip39, change '0' to '1' in "External/Internal" in derivation path to see your change addresses.

m/44'/0'/0'/1 - you can also copy-paste this if derivation path is not as detailed as the above tool.


Ask their support. They won't reply in this forum.


Transaction fee will pretty high if you use faucets or gambling sites or receive many (micro) transactions. Transaction fee will only increase for such users if change addresses are also used. If you don't want to use new addresses per transaction, get private key of that address from seed (12-word recovery phrase) and import it to your wallet.

Note: Don't use two wallets with same seed. E.g. Blockchain.info + Copay or Blockchain.info + Mycelium or Mycelium + Bither etc. If you send Bitcoin from wallet₁ and it send change to a new address, that address won't be shown in second wallet. Thus, Bitcoin sent to that address won't be shown as you balance. Don't do it unless you know your stuff!

Receipt - a writing acknowledging the receiving of goods or money.

Other mixers send Bitcoin directly to address we give them. After they send Bitcoin to our addresses, they give us receipt or signed message saying they have send x.xxxBTC to

. However, ChipMixer doesn't actually send Bitcoin, they give us private key related to the address which has Bitcoin. Either we or ChipMixer can send Bitcoin from that address. In worst case, a hacker if the private key was stolen. So they can't give a "receipt".

If they give receipt after mixing and before they give us private keys, then they are essentially saying "we paid you" even before "paying" us. That is not a "receipt".

If they give a signed message mentioning they have sent us private keys like they are already doing, that is only a "receipt" saying "we have send you private key(s)", not "we have send you Bitcoin" because they can send Bitcoin from that address anytime if they want.

ChipMixer's signed receipt:

Code:

--- MESSAGE ---
This is a receipt / confirmation that you have received following
private keys from ChipMixer:
### CHIP SIZE: BTC
Address:

; Private key:
### CHIP SIZE: BTC
Address:

; Private key:


This message is signed with ChipMixer's Bitcoin address:

--- SIGNATURE ---

First of all I find it extremely unlikely that any competitors would want to 'frame' chipmixer as a scammer. That is extremely unlikely. There is a possibility that a user just wants to get free coins.

Be in a safe environment and make sure your computer is free of viruses. Chipmixer has no reason to steal your money when they've spent so much on developing and promoting this. Sweep the keys if you need to.

I find it odd that people think chipmixer is somehow less trustworthy than other services who just send the coins directly to you. If you think about it it's about exactly the same likelihood that they will scam, which is almost zero especially if dealing with small amounts.

You have misunderstood something! By not giving us receipt, even if they do steal, we can't prove because we also have access to the funds which makes it easier for a scam to happen. It does NOT mean other services are safer! Just that if they send to a wrong address or if the funds were stolen, we can prove it in most cases and ask them for a refund. For ChipMixer, it is not possible even if it is their fault.

P.S. A hack/steal could also mean stealing private key from their server. Although chances of happening this are very low, it could happen. I hope if this is the case, ChipMixer will give a refund!

They CAN scam us and they MIGHT scam us! But it does NOT mean they WILL! Like others have said, it comes down to how much you trust them. ChipMixer offers features others don't offer and there are drawbacks for offering such features. If you don't like ChipMixer or is afraid they may scam you, don't use them! FYI, I have used ChipMixer recently! Both their service and their support are great!

Download https://github.com/iancoleman/bip39 and open it. Enter your 12-word seed (aka recovery phrase) in "BIP39 Mnemonic". Scroll down and you will see your addresses and private key corresponding to each one. Import private key of the address you want to sign with into a wallet such as Electrum, Bither or Blockchain.info or use a tool like https://github.com/weex/bitcoin-signature-tool.   If you want to sign message with a "change" address, change '0' to '1' in "External/Internal".

Only an admin can help you! Currently, only theymos and Cyrus are admins. Asking anybody else to recover account won't help you and you will only be wasting your time. Use your current account until your old account is recovered. There is no need to wait until your account is recovered to post.

@OP: If you are unsure whether you have linked your email with Blockchain.info or not, you should do as hilariousandco said. You maybe lucky!

P.S. Check "sent" & "draft" folder in your email account. It is possible for you to sent Blockchain.info support your identifier if have you contacted them.

Even if she is really an extortionist does not mean she should be removed from default trust list. As long as she had good judgement and is accurate in giving feedback, her being in default trust list in fine.


I think she is rash.


Was there more than one case? Can you back this up? I have read previous incident, but I didn't find any other. I am not very active in 'Scam Accusations' board now. I could have missed it if there was any.

His posts were deleted. As there is no post to show, "sorry, no matches were found" is shown. If you check general statistics of 'logonowpls', "no posts to speak of" is shown. I think even his post count and rank will be reset after sometime. I am not sure about it though!

If you are going for pool mining, choose your pool carefully! See https://www.bitcoinmining.com/bitcoin-mining-pools/ and https://www.blocktrail.com/BTC/pools.

Don't spread misinformation! Anonymity is lost when using hardware wallets? Where did you hear that? When you use hardware wallets (normally), your anonymity is not compromised.  You WILL loose anonymity if you use online wallets because they will know your IP and all addresses in your wallet. They can basically track all your activity.

You can't sign messages with addressss created in new Blockchain.info wallet. If you have imported private key or if your addresses were created in old Bloclchain.info wallet, you can sign messages. If you want to sign messages with addresses created from new Blockchain.info wallet, you will have to first get private key of that address from seed (aka 12-word recovery phrase) and then import private key to a wallet or use a program only for signing messages.

Address starting with 1 is pay-to-pubkey-hash (P2PKH) and address starting with 3 is pay-to-script-hash (P2SH). You can't interchange 1 & 3 or any other letter in an address. It will result in an entirely different address than yours or end up with an invalid(unusable) address.

No, you can't! If you are going to create a new wallet in Blockchain.info, don't forget to write down your seed (aka recovery phrase). It will help you to recover your private keys even if you forgot identifier and password.

Use rpcauth.

You have clearly said it yourself that wallets do not require personal information, so why bring exchanges? Wallets and exchanges are for different purposes. Wallet is for *storing* Bitcoin, while exchange is for *trading* or *exchanging* currencies/assets. Because of legal issues, exchanges do require personal information *for trading* [above their limit]. If you use it *only* for storing, there is no need for ID verification, but I absolutely deprecate using exchanges for storing your bitcoins.

You need at least 775 activity to have a chance to become legendary. For your activity to reach 775, it will take ~44 periods (1 period = 14 days), i.e. ~88 weeks = ~618 days.


You're welcome!

If you use a transaction which uses an input which is considered as invalid by a node, your transaction won't be mined and hence, unconfirmed forever. All nodes reject double-spend transactions or transactions which use a double-spend transaction as input or a transaction which uses an unconfirmed input which has double-spend transaction as input and so forth. But for some reason, Blockchain.info don't do that. Blockchain.info's mempool configuration is different from other block explorers. Therefore, you will be able to see such transactions and also "unconfirmed" balances in Blockchain.info.

Mempool - A place where node store transactions which it consider as valid. You can configure it in different ways.

https://bitcointalk.org/index.php?topic=1939408.msg19284845#msg19284845.

P.S. Normally, nodes also reject dust transactions, though, afaik blockchain.info don't.

Edit: Like crairezx20 already mentioned, this thread is closed. So please create a new thread in Development & Technical Discussion board if you have more doubts.

To calculate transaction fee, I recommend https://jochen-hoenicke.de/queue/#24h using as reference.

Blockchain.info now uses hierarchical deterministic(HD) wallets. Many HD wallets don't allow you to sign messages. You will have to use tools like https://github.com/iancoleman/bip39 to first find private key of the address you want to sign message with and then import address to a wallet or use a tool.
