Guys many thanks for explanation & advices.
It ain't much but every sat counts Smiley. I used this in the early stage of faucets when btc quite cheaper than nowadays and was just playing around, educating family & stuff with TXs etc. using other 3rd party services (ofc I warned everyone about the not owning PKs) so that's the main issue, no address with own PKs  Cheesy

I will still try to find out what's the matter with the emails because till end of February I was receiving them without any problems. It has to be definitely possible to identify the root cause of not coming mails, it's a stupid issue imho.

I tried to propose that I'll deposit some stack of sats with signature, but got no response on that so I don't know if that make sense, I just thought that it'll proof enough that it belongs to me (who will deposit to the foreign account)? But got no response on that. Using that approach I just wanted to simply proof it & change the email address...

I will keep fighting and let you know, because that can happen to anyone, so I would firstly suggest to change the withdrawal address in the profile (mine here is the default one used for deposits)

BTW sorry for complete offtopic in here if some mod would decide to make a separate section about freebitco.in issues, kindly go ahead. I am just truly reader and once I faced this I just had to reply  Cool

No problem.

Custodial service-related issues can be posted in this board: Bitcoin Forum > Economy > Marketplace > Service Discussion
If you got further concerns or updates, you can create a thread there.
They've also got their own thread in Gambling board: https://bitcointalk.org/index.php?topic=320959.17000 (link to the current last page)

No, this tutorial thread for bitcoin, you must try sign message in bitcoin wallets such as bitcoin core or electrum. The method is the same away as what you have tried - Verified -

Posting a Bitcoin address sign message can also be used for the account recovery process, so I suggest that you save the information carefully to be able to access the bitcoin address.

Maybe you can consider posting it in the following thread:
Stake your Bitcoin address here

Thanks but there is still something I don't quote understand.  When I signed my message, I used the received address in the wallet, and the address has $0 balance.

Let us say I wanted to send some bitcoin to someone, and they wanted to verify that I had the funds to pay for the transaction.

Is there a way I can 'sign' a non-zero address containing the required funds to show that a) The $ is mine to send and b) The $ is enough to cover the cost of the transaction


Would it be possible ? - (or even make sense?) to sign the message in such a way that  ? - It seems it should, I just think I'm missing something

Tks.

The signing process of funded addresses is the same as for empty ones. If you sign a message from an address that contains bitcoin, you effectively own that address and the coins in it.

Regarding point b, it depends. If you are supposed to send a client 0.2 BTC and you sign an address which contains only 0.1 BTC, the client will know (if he checks) that you don't have the required amount. If it's the other way around, he can see you have enough.

When you can sign messages from a Bitcoin address, you can also access the assets there. It's because you have access to the private key or seed of that Bitcoin address. Other people who do not have the private key/seed cannot create a signed message from your bitcoin address, for example:



As Pmalek explained above, when someone wants to know if you have enough funds or not to send from the Bitcoin address to which you signed the message, they can see it through Bitcoin Block Explorer, e.g.: https://mempool.space/address/1Apqmd4bQBaazqvRPA4Si8LzLvGjRaf3bQ

Okay so as a test I sent 2 transactions to my bitcoin wallet.

One for        0.00011792 BTC to  1Apqmd4bQBaazqvRPA4Si8LzLvGjRaf3bQ (the one I signed already)
Another for  .0.00011828 BTC to  1PMHH5BHtr1WEpesJcBPBZ2FZDdfURkohG (which is address that appeared in the receive after the first transaction)

My wallet showed the sum of both addresses once confirmation was completed.

Then I sent 0.00016200 BTC back to the originating address.

The receiving block chain transaction https://mempool.space/tx/4b941d7b2b0bc274f90d4d8310fbed3e640ffe9a5924389b73a85870b72d7cb9

Shows that most of the BTC came out of the second address (emptied it completely) and 0.00001200 BTC came out of the first address, and I'm assuming carried with it a hefty fee do to the small amount in the transaction of the second address ? (Fee was like 0.00007420 BTC)

So.. it seems, that the balance in my wallet, is simply the sum of all addresses in the blockchain for which I can 'sign' for with my private key.

If I had sent x bitcoin distributed over 20 addresses, I would have to:

a) Consolidate them amount all into one address before sending (which I'm guessing would also save me on tx fees?)

b) Send signatures for every address in the transaction to prove it was me that sent the money for all of them
(and not just 20 other random people sending small amounts)

Am I understanding this correctly?

I guess,

For a: If the process of consolidation is free or it doesn't charge you more than the other process, then consolidate it.
For b: If you consolidate and make the payment from a single address, then you only need to sign from that address.


(not really sure if this is correct, since I used a custodial wallet more)

edit: btw this might be a little off-topic, so may I suggest next time to create a different topic.

The amounts that are being transferred don't affect the total fee that the sender has to pay. The fee is determined by the number of inputs and outputs, type of addresses being used (Segwit or Legacy), and things like 2FA, multisig scripts, etc. That transaction of yours had two inputs. If one of the addresses you initially sent to had enough coins, you could have used only that input and paid less in transaction fees. A transaction of 0.00016200 BTC made up of 2 inputs is more expensive than a 1 BTC transaction that only has 1 input (if the same sat/vbyte fees were used).   

So.. it seems, that the balance in my wallet, is simply the sum of all addresses in the blockchain for which I can 'sign' for with my private key.
Private keys - plural. Each address has a different private key.

a) Consolidate them amount all into one address before sending (which I'm guessing would also save me on tx fees?)
If you consolidate your inputs at a time when the transaction fees are low, you will save money when it's time to move those coins elsewhere since you will only be spending from 1 input. Remember what I said before, the amount of coins you send doesn't affect the mining fees you pay. Inputs and outputs do. 

b) Send signatures for every address in the transaction to prove it was me that sent the money for all of them
(and not just 20 other random people sending small amounts)
Another reason to consolidate and avoid the hassle of multiple signed messages from multiple addresses.

The instructions are in the first page - first post.
If your wallet is not in the list, try to find a similar feature in your wallet, usually, it's named as "sign message".

If there's none, you can import the private key of the address to one of the wallets in the OP with "sign message" and "import private key" feature.
Then sign a message using it.

Signing an address is to show ownership of it, and this is only proven by showing access to the private keys.
The public address is accessible by others and the public key is revealed when an address signs a transaction, but the private keys are only accessible to the owner of the address (except when compromised) that is why it is used to prove ownership.

How come you get only public address without acquiring public during your wallet setup? If you are just recently created a wallet, you will get 12 word seed phrase instead of private key if you use electrum wallet then proceed on the instructions. You might counter some changes since the guide is outdated due to inactivity of OP.
