Topic: Can you use the same address to send AND recieve Bitcoin? - page 2. (Read 700 times)

The second one.
The first was her deposit TO the casino.
The second was the casino's pay-out to the player - which she says never appeared in her wallet.

Shouldn't we also need a transaction ID from the casino to the customer, so we can figure out where the money ended up?

The address 1AWFZhxpQGMmSv9KQjRHi1j4bdhPkhh5Qs is highly unlikely to be owned by the user in question. It is used as an input to two transactions which each have hundreds of small inputs being consolidated in to one. It must either be the user's deposit address on an exchange, or their deposit address on the gambling site. Since OP said the user in question is using Coinbase, I followed the consolidation transactions along the chain a little, but could not find any obvious link to known Coinbase addresses (although I'll admit this was a cursory search), which led me to believe that the address OP gave was the deposit address from the casino. However, even if that is a Coinbase deposit address, it doesn't tell us anything useful since the transaction from Coinbase to the gambling site would have come from their hot wallet and not from the user's deposit address.

Ideally, we need the transaction ID of the deposit to the gambling site.

It's hard to come to a conclusion here when we're dealing with bits of information only and if I understood correctly, CasinoKing is just an intermediary, i.e. a third party, not an actual casino player.
CasinoKing, if you have any communication with the player, ask her to give you the correct TXID (transaction ID) of the casino payout. This can be found in the withdrawal log in the casino user interface or can be requested from the casino customer support.

Second, ask the customer what exactly was the wallet used to deposit funds into the casino? If it was Coinbase or some other web wallet, please have the exact web address forwarded here. Just to confirm that this is a legitimate service, since there are several fake websites as well.

If all this checks out, the next step will be for the user to open a support request to Coinbase customer support with all relevant information as they are the only ones able to forward funds to the user's account if they received a transaction to one of the addresses that is part of their wallet.

Casino or exchange have hot and cold wallets. Most of time, when you make deposits to their platforms, your amount of deposit will be moved to their cold wallets (sometimes are not). Your receiving address is used for your deposits or for your won amount (if you win). Platforms can credit you a balance for your deposit or your win by their internal feature.

Some platforms only have each user has only one receiving address so yeah it is clear that you will have a same address to receive your money from won bets.

Some platforms allow you to create new receiving address but your old receiving address will still be reused to receive bitcoin. Old and new addresses are coexisting in a single wallet that platform created and allocated it to your account.

I think he's talking about the address from Web wallet based on the first post.

@KasinoKing
Why not check the Casino where she gamble I'm sure they have something like withdrawal history that you can check then get the transaction link and paste it here.

So that we can check if the transaction from the gambling casino has this address "13iwmRvSV2ZwnEu78BGiHChkVq986TU9WQ".
If the transaction made from the Casino doesn't have this address well, it might be sent to a random address.

Why not try to ask her the exact website of the wallet so that we can check if it was a legit wallet or not.

Sorry, it wasn't my intention to sound like a douche. I'm still new here, so that was my attempt at humor (hint: little smiley).


Well, live and learn. Thank you for that!
I was just trying to help a member who is new to the crypto world.

If you are correcting other people while sounding like a douche, at least don't make mistakes.

For example, i could quote your post and say:
Please don't call an address a public key. It is such a misnomer that it almost hurts my brain when reading that you don't know the difference while correcting others.

Am i going to do it? No.

Instead, i'm going to say:
Dear BurningChrome, please keep in mind that an address is not the public key. With P2PKH for example, the address is the hash of the public key. Thanks.

Please don't call it "a number". It's such a misnomer that it almost hurts us when we read it.  

To avoid any confusion in communication, this string of alphanumeric characters is best referred to as a Bitcoin address (BTC address) or your public key. Remember the difference between a private key and a public key. You should NEVER share a private key with anyone or publish it anywhere.

This is the address she sent coins to that is owned by the gambling site?

There are two payments to that address - one on September 16 for 0.00242101 BTC, and a secnd one on October 28 for 0.02724758 BTC. Which one of these two payments is the one which is being disputed?

Thanks once again to all who replied!

1. I have no idea what type of wallet she is using. But as she's 70, I would guess web-based.

2. Yeah - I made up most of that number as I wasn't sure it was a good idea to post the real one!
But I guess it can't do any harm, so here is the actuall number:
1AWFZhxpQGMmSv9KQjRHi1j4bdhPkhh5Qs

I know this can be viewed on the blockchain - but it's like a foreign language to me, so maybe you guys can see what happened...?

Cheers,
Mark.

@KasinoKing, o_e_l_e_o and ranochigo have given you good instructions. Proceed as suggested.

Find out the TXID (hash) from the casino's payout transaction. Then we'll be able to check where the funds ended up.

Most of the exchanges have a different deposit address than the ones they use to pay, and that's why they don't share the private keys with their customers. So I wouldn't recommend sending money to an addy where you get the payment from an exchange.

The right way to receive and send money from the same address is with a propper wallet (One who let you import and export the private key)

A lot of misunderstandings come from the fact that there are no addresses on a technical level.
Addresses are a construct made for humans.

You could (only in this case, please don't generalize it) imagine an address as your bank account.

You can receive BTC by sending them to your address (just as depositing them to your bank account).
But you can also send BTC from your address (just as sending/withdrawing from your bank account).

A transaction has a sender and receiver. Sending the coins "back to the same address" means that the sender of the first transaction is now the receiver.

On the blockchain, the transactions are completely transparent. You'll know if a transaction spends an input from certain addresses. By recognising the origin or the path that the funds take, you can deduce with a reasonable accuracy that it is from a certain service. It's especially so since most gambling site uses a single address (or a bunch of known addresses) to store their funds as well.

Can the casino provide a transaction ID (hash)? Can you see the transaction hash on a blockexplorer (blockchair.com)? Is the funds in the transaction going to the right place? If the answer to any of that is no, then they haven't send the funds.
Deposits are automatically credited on Coinbase.

Coinbase spend a lot of time and effort to deanonymize bitcoin addresses. It can be as simple as making a deposit to the casino and watching what other addresses the coins are mixed with.

Is the player using a Coinbase exchange account on the web or the exchange app, or have they downloaded and are using the standalone Coinbase Wallet app?

We don't need to believe - we can check. Ask them for the hash of their deposit transaction, or the address they sent coins from. The address you gave in your first post is empty.

If you can answer my above questions, we can help to figure this out.

Thanks for all the replies guys!

I don't know that Coinbase know it's from a casino.
But Bitmazx said Coinbase do not accept casino transactions (which I also did not know!), so what I am asking is how COULD they know where the funds are coming from.

What I didn't mention, is the reason I started this thread in the first place, is that the casino say they sent the funds, but the player has not received them.
But I did not know if it was possible for them to send back on the same #.

I don't know the player - they contacted me via another forum to ask for help. But I do believe what she is telling me.  It's not a lot of money.
But I do know the casino, as I have been working with them (as in promoting them on my websites) since 2008.  So I do believe what they are saying too.

So the big question is, if the casino sent the funds but the player didn't receive them, where have they gone???

Would the player have to do something in Coinbase to "claim" the coins?
Or should they just automatically appear in her Coinbase account?

Cheers again!
Mark.

You should ensure you have set a return address for refunds, (or in this case payouts) PRIOR to making any withdraw claims - hope your "friend" is able to get their crypto out quickly.

Technically, an address is just a human-readable representation of a script (eg. scriptPubKey),
which can be 'spent from' by fulfilling the requirements of or solving that script.
Each transaction's output(s) creates a new UTXO (unspent transaction output) that's locked by that script and that's what's being spent, not some kind of balance for that address.

TL;DR: Let's say an address is a "padlock" (not the box that's being locked), its private key is the key for that padlock,
and the UTXO(s) that can be spent by your 'key' as the box which being locked by that padlock.
A padlock can be locked and unlocked as many times as you want. (not the best analogy since each UTXO requires different signatures)

I can't find any article that states "Bitcoin is Anonymous",
it's rather "Pseudoanonymous" which could mean it's anonymous in a way that you have the option to not link your identity to your addresses.

No they aren't. An address that belongs to you can be used to receive and send funds repeatedly.
It isn't. It is fairly easy for anyone to be able to trace transactions. The coins are usually sent to a known address that is controlled by the casino. Afterwhich, it is likely sent directly to your address. Coinbase can reasonably link the connections and deduce that you're sending the funds from a casino.
