This problem lies in their side and since you have already sent a support ticket to them, what you can only do now is to wait for their response.
Did you reference your TXID and your transaction history? as it can greatly help for them to solve your issue as soon as possible.


It's a normal practice for most exchanges and it's most likely for security reasons or for organizing addresses/funds. There's nothing to worry about as long as the exchange is reputable.

I haven't bought bitcoins in blockchain.info as it is not available in my country although to get to get the most accurate percent rate of your transaction, you should have get the buying and selling price when you made your order not in the price you paid and it's current price now since bitcoin is highly volatile so the price you have seen a few hours ago may not be the same now. Looking at the charts, it's constantly falling, probably because of the price correction


Look at your order history, blockchain.info promised that you will get an amount of .00912182BTC so for obvious reasons, you got an exact amount of bitcoins in your wallet

To add on, It'll be more expensive if you use such alternative because of multiple deposit/withdrawal (miner fee) and trading fee's, furthermore the bitcoin network is still congested up until now so every on chain transaction requires a high miner fee (compared than usual).

Meanwhile if use an actual mixing service, you will only need to pay for the miner fee of a single deposit and withdrawal as well as the mixing fee.

In chipmixer's case, you can withdraw through private keys so you can just import it into another wallet to avoid another miner fee.

Signing a messsage is only available for imported addresses, If the address is a part of your HD wallet, then that feature won't be available. Quoting it with the link you provided:


But there are still ways to sign a message

1. Using some third party tools:


2. Importing it in another wallet and signing a message there. I recommend electrum for that

Using your seed/backup phrase:


Here's a tutorial to sign a message in electrum: https://www.cryptocompare.com/wallets/guides/how-to-sign-a-message-with-electrum

You can also import just one address using its private key. Use the iancoleman bip39 tool for deriving your PK's as mentioned above
Guide: https://bitcoinelectrum.com/importing-your-private-keys-into-electrum

This is a problem in their side so they're the only ones who can fix it. You've done your part now that you've sent a support ticket regarding this problem.
I'm sure they are already aware of this considering that you're not the only one whose currently experiencing this: (but I'm not sure if they're fixing this or what   )

For now, If you want to access your funds, you can import it in another wallet using your recovery phrase/seed. You can find a tutorial in the links stated above^


Can you post the TXID's here?

What kind of hacking attack? Attack on their system where lots of btc's are stolen or just from your account only? but since your private keys are stored in your email, your funds have a 99% chance of getting stolen.

Before anything else you should verify their credibility first.
Can we know the name of this site? If it were really running for 4 years without a problem, it should have some kind of reputation here.
(For safety reasons, Post the link like this: poloniex[dot]com)

If you see an unauthorized transaction then yes, your wallet has been compromised and unfortunately, bitcoin transactions are irreversible and pseudonymous so getting your bitcoins back is pretty much impossible.

But what intrigues me is where did you buy these coins? If I understood correctly, You bought bitcoins from X and X gave you the address and private key funded with those coins through email which is highly dangerous as it can easily be hacked. If it is, You are most probably been scammed by X.

A must read announcement from shapeshft since you submitted a support ticket: https://www.reddit.com/r/shapeshiftio/comments/7layhk/a_note_about_the_current_state_of_the_ticket


Yes the miner fee would be expensive since the bitcoin network is still congested although it has stabilized a little. In shapeshift case they are using a fixed rate regardless of the transaction size. Here's the current rate:


I'm not sure if they have increased the fee higher than what is stated above but as you can see it's just .002BTC now so if you get a refund, only .002 will be deducted.
*Note that miner fees doesn't go to shapeshift!!!

And looking at your order ID, It's not entirely their fault because:

First, you chose "Precise" which has a time limit for deposits but you only included a fee of 61 sats/byte which is fairly low and as a result it got stucked for 3 days, and obviously your session expired. You'll see in the upper right: "Time Remaining Expired!"

If you're not even spending an amount greater than what you have but you're still seeing the error sign then please refer on my previous post as this is most likely a problem in blockchain.info's end so for obvious reasons, they're the only ones who can fix it.

I think bitpay and copay is pretty much identical since I imported my bitpay wallet to electrum a month ago. If my guess is right both uses BIP39 for their seed.

You can try importing it to electrum using your seed. Below is a tutorial for that.

So meaning to say, there's nothing on your withdrawal history that states that your coins were withdrawn in an unknown address? If so, you should contact their support to clarify your situation. Please make it as detailed as possible and it should also be followed by proofs e.g. screenshots since waiting for their response is slow enough but if your support ticket lack essential details then it will be slower than that.

But If you see in your withdrawal history that your coins were withdrawn in an unknown address, unfortunately most cryptocoins are irreversible and pseudonymous so its nearly impossible to get them back.

I'm not sure but there are a lot of people complaining about them recently so If I were you, I wouldn't use them now.

Yes it'll be expensive compared to normal because of the network congestion, I think your deposit has to confirm in the nearest block as much as possible because I've seen a lot of users whoose transaction (deposit) got stucked for days and it's either "trade failed" or stuck to "exchange in progress"if it ever confirms after those days. As for withdrawal fees they released a list of it, since exchanging in blockchain.info is powered by shapeshift, I think these also applies to them https://info.shapeshift.io/about

This address (1EtuLFnTQt9sEWpQYnPUFVJrocEEbSbVWb) really has no btg's and that is because if you look at its transactions, all funds were withdrawn at block 478736 and that means that it doesn't have any bitcoins stored at the time when the snapshot took place (Block 491406). If I'm not wrong since its a fork of bitcoin, the transaction history in it should still be identical until the snapshot.


The address (17qrzjzzwZHa822cAbe1TL7B4zzKki5D9u) where the .1BTC resides must be a change address. I checked it with block explorers and it has a balance of 0.10120542 BTG, And its equivalent address is this: GQgnQsKwvQtsCVKu6YJ7t6T4zAnAoyzQJg.

Is this still from your HD wallet in blockchain.info? If so you can again use the tool and follow what HCP says to check your change addresses private keys.

Most services claim that majority of their funds are stored in a cold storage but we can't really verify if it's true. When you deposited your money on these third party services,
you are trusting them with your funds so in short it's all about "trusting" that what they claim is true. Meaning to say, its impossible to know what kind of wallet they are using unless you've seen them for yourself but they can just claim whatever they want.

And every address has a corresponding private key, it's just that some services don't give their users an access to these.

From my understanding, You kept your bitcoins in blockchain.info until november? or you transferred bitcoins into blockchain.info this november?

Because only bitcoin holders who had bitcoins at the time of the fork (block 478558 - August 1st, 2017 about 13:16 UTC) will be credited.

Have you already tried checking the address/es in any BCH block explorers? If not, Try pasting it from the links below:

• https://bch.btc.com
• https://blockchair.com/bitcoin-cash/blocks
• https://www.blocktrail.com/BCC
• https://bitcoincash.blockexplorer.com

From what I know, Despite the price increase polo still holds the cheapest bitcoin withdrawal fee (miner fee), The second one would be hitbtc which is 85K sats and then the average would be .001BTC but please note that most of them changes their withdrawal fee depending on the current network condition, for example if the network is congested then the fee will obviously increase.

And most exchanges will allow you to trade <500k sats and if by any chance they don't, there will be a caution sign so you'll be fine as long as you pay attention on your surroundings.

BCH is different from BTC as they are in different chains although both of them can use the same addresses as well as private keys which is why technically, you can still get your btc's back if you sent them to a BCH address or vice versa as long as you hold an access on the private keys of the address where you mistakenly sent the coins. In your case it'll be a little different as coinbase is the only one who have an access to their user's private keys so the decision is up to them if they are willing to retrieve those coins back for you.

That is why people should stop using third party wallet's like coinbase   

I think you have a very slim chance of getting it back  


There was also another user who had a similar problem such as yours. Unfortunately, coinbase didn't retrieve it back for him.

Reference:


Then again, to get things clear, you should still contact their support like what the above users have mentioned.

Yes


There is no feature like that in blockchain.info's dashboard. For you to access your private keys, you have to use a third party tool like this one: https://github.com/iancoleman/bip39 (Download it and run it offline)


Enable the Developer Menu (Ctrl+Shift+D) after that Go to Exodus --> Developer --> Assests --> Btc --> Export private Keys

If you don't mind, Can you tell us from which country do you reside?

Have you already tried checking this site: https://localbitcoins.com because most countries are there. Just make sure that the individual you're trading to is "trusted", check his feedbacks, confirmed trades etc.
