Yup, definitely a scam. Created a second a/c in my Mycelium, used that. Interesting that the address is verified first - I deliberately put in a typo, and it came up with an address validation error. When I corrected the address, the following came up ...

"You can withdraw your funds only on external address, which is registered and verified with your account. To verify your (external) address with your account, you need to make a deposit from this address. Deposited amount will be added to your current balance amount and will be available for withdrawal at any time immediately. More information you will find on Deposit area in your profile. Minimal amount of the deposit is 0.01 BTC. Current deposit status: 0 / 0.01 BTC. "

Which of course I have no intention of  doing.

So, yup, looked like it was indeed too good to be true.

Thanks very much everyone.

Thanks. What's the purpose of the tracking then - what benefits could they get from doing this?

Well the blockchain stores the sending addresses and receiving addresses for each transaction. The company would be able to do some deanonymisation techniques (potentially) which could do things like link your bitcoin wallet to your ip/name if it's in an email signed up with. It's more of a thing thatd just seem a bit weird and if you wanted to stop that, you could just send the funds to a trusted exchange instead.

OK, I created a second account, they wanted a deposit.

Thanks mate.

If you give them an address from mycelium (downloaded from your app store) the most they can do is send funds to it and see what your address is doing.

I'd make a new account purely for the second thing and then pass the funds through a mixer if possible - like chipmixer - (or an exchange like binance) to try to break the chain of tracking they'll be able to do if you send within your own wallet.

I got a message on discord (i sign up to a particular server) from an individual informing me that I've been given some bitcoin (0.2) . The message was to the effect that their exchange has increased activity and decided to hold a draw, distribute to random users. Crazy eh? Sticking to the tried and trusted old adage, if it sounds too good to be true, it probably is.

Nonetheless, I followed the instructions, signed up to this somewhat-dubious exchange website, put in the activation code. I now have the option to withdraw the bitcoin. When I select "withdraw", I am asked for a bitcoin address.

I have a mycelium wallet. when i click on Account 1 (now working with on this HD account), and then "balances", it shows an address. Is it safe to enter this address into this somewhat dubious website? Or shall I create a second account in mycelium? Or better yet, forget the entire thing?

Sorry for your loss.
Damn, this bitcoin stuff is incredibly complicated.
It could be complicated, but all you need is a bit of research, a lot of people played around with Bitcoin early on without fully understanding it and lost access to their coins through carelessness. The simple rule to follow is 'not your keys, not your coins'. So basically having access to your private keys gives you ownership of your Bitcoins, preventing anyone else from having that access protects you from loss and backing up your private keys means you can always recover it in case you lose your device.
Private keys are represented as 'seed phrase' or 'recovery phase' which consists of group of 12-24 words. This makes it much easier to back up.

Better luck care next time.

Cheers mate.

Yes, I do see the balance.
I emailed the key to myself, so technically, its very risky I'm guessing, since i just added the key to mycelium, and just like that, i got a balance.
I eventually found what looked like a "key" which I had emailed to myself - a string of numbers and letters. I didnt write anything else, just this string of numbers and letters.

I have mycoleum with  "Bitcoin HD" account. I decided to enter this string of numbers and letters. I can't remember exactly how i did this to be honest, i think it was trying to import this key.
Before concluding that you have the balance, click the "SEND" button in Mycelium's 'Balance' tab while the "SA Account" in 'Accounts' tab is selected.

Because you can create a watch-only SA account if you've pasted a bitcoin address instead of the private key (and it'll not be labeled as watch-only).
And since private keys and bitcoin addresses both consist of "numbers & letters", the one in the email could also be an address.

To clear the doubt, try to click "send", if it continues instead of a long watch-only note, then it's spendable.

Oh no!! You are right, it is a watch-only account!
Well I'm stuffed then. it says i need to import the corresponding private key. I don't have it.
Ah well, easy come, easy go.

Damn, this bitcoin stuff is incredibly complicated.

Not the news I was hoping for, but thank you anyway.

Can you see a balance in mycelium? If not then you might have found a key for the wrong thing or something. How did you go about finding the key, was it in a file somewhere or something?

Yes, I do see the balance.

Thanks for your help dude

beginners. Understanding bitcoin private key

Hi,

A couple of years ago, I bought some bitcoin ( about £10gbp) . Then I forgot all about it, and forgot what I did with it.

Now that the bitcoin rate has gone up, I decided to search for any trace of the purchase.

I eventually found what looked like a "key" which I had emailed to myself - a string of numbers and letters. I didnt write anything else, just this string of numbers and letters.

I have mycoleum with  "Bitcoin HD" account. I decided to enter this string of numbers and letters. I can't remember exactly how i did this to be honest, i think it was trying to import this key. anyway, I can't be certain, but I "think" this import seemed to work. mycoleum now has two accounts: the already-existing "Bitcoin HD" (hierarchal deterministic) which I had before, and a new "Bitcoin SA" , (SA - which Im guessing could mean Satoshi? ).

Anyway, a few questions:

Have I done this correctly, and can I now use this imported bitcoin in mycoleum and convert it to GBP?
If someone had "gotten" hold of my private key before I added it to mycoleum, would adding it to mycoleum still have worked?
When adding this private key, what exactly is it that I added? Is it a wallet?

Thanks
