Can you use the same address to send AND recieve Bitcoin?

[OcTradism]

They sent a small amount of Bitcoin to an online casino using a standard address. e.g. 1AWFZsieMdJH8HJeT956HdhsPjhsf3S
Having won and cashed out, the casino says they sent the winnings back to the player USING THAT SAME ADDRESS.

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.

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.

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

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

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.

[Marvelman]

...

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

[KasinoKing]

1AWFZhxpQGMmSv9KQjRHi1j4bdhPkhh5Qs

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 second one on October 28 for 0.02724758 BTC. Which one of these two payments is the one which is being disputed?

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.

[o_e_l_e_o]

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.

You misunderstand. The two payments I am talking about above both go in the same direction - TO that address. One cannot be her deposit and the other the withdrawal, as that doesn't make sense. If that address is owned by the casino, then both those transactions are deposits TO the casino.

You are not giving us enough clear information to help you out here, I'm afraid. We need you to answer very clearly the following questions:

Is the address 1AWFZhxpQGMmSv9KQjRHi1j4bdhPkhh5Qs the address she sent coins TO when depositing to the casino?
Can you provide the transaction ID of this deposit transaction?
How much did she deposit, and on what date?
How much was the pay-out she never received, and on what date?

[bob123]

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.

No, it wasn't.

As i tried to explain earlier.. look at the address as a bank account.
You either pay to that bank account or receive money from that bank account.

You can't sent money twice to the same bank account and say once i sent the money and once i received it.. This simply doesn't make sense.


If your "friend" or whoever you are helping, did not receive a transaction ID, he/she should contact the casino or whoever should have sent any funds back.
At the very least, we need to know the address your friend send the deposit to and preferably from which address.

Well that's EXACTLY what I thought and the whole reason I started this thread in the first place!

But in some of the earlier replies, people said it WAS possible to send and receive using the same address.

So let me be clear:
The player deposited approx $26 on Sept-15th sending to address 1AWFZhxpQGMmSv9KQjRHi1j4bdhPkhh5Qs
She played and won some money.
The casino says they sent approx $360 to the player on Oct-29th using the exact same address: 1AWFZhxpQGMmSv9KQjRHi1j4bdhPkhh5Qs

So now you're telling me that is NOT possible?

Mark.
PS: Sorry for the long delay between my posts - I only get the chance to visit the forum like once per day-ish as there is just so much going on here at the moment.  I really appreciate everyone trying to help though! 

[o_e_l_e_o]

But in some of the earlier replies, people said it WAS possible to send and receive using the same address.

It is, but the same address can't belong to two people.

Your friend can send bitcoin from her own address 1xyz... (for example) TO the casino's address 1AWFZ...
For the casino's to return the coins to the same address she paid from, they would send coins back to 1xyz...
There is no point them sending coins to their own address 1AWFZ...

Having said that, it does appear this is what had happened. I also stumbled across this thread on another forum where you are discussing this. It would have been much easier if you linked this thread earlier: https://www.casinomeister.com/forums/threads/thebreeze1355-vs-rich-palms-casino.93277/

Between that thread and the blockchain evidence, what I can ascertain is the following:

The user deposited 0.00242101 BTC to the casino's address 1AWFZhxpQGMmSv9KQjRHi1j4bdhPkhh5Qs in this transaction: https://blockchair.com/bitcoin/transaction/b8695c54fbce14dbd7f2c8026851530e5ee77410e8c05e13f273d4c9975a7956

According to this post (https://www.casinomeister.com/forums/threads/thebreeze1355-vs-rich-palms-casino.93277/post-1170323) the casino emailed her with the above address as an example of a deposit address she needed to provide for them to process the withdrawal.

According to this post (https://www.casinomeister.com/forums/threads/thebreeze1355-vs-rich-palms-casino.93277/post-1170362) she then told them that "that must be the right [address] if that's what they had".

The casino then sent 0.02724758 BTC to their own address in this transaction: https://blockchair.com/bitcoin/transaction/25a4fe55735affcd9fbad0e10d9ebb500916bce9eb1c49734361c165e924ae57

So it seems that the user accidentally told the casino that their address she deposited to was in fact her own address, and the casino accidentally processed her withdrawal without realizing they were sending coins to their own address. She should contact the casino with her real withdrawal address, and explaining the above. Link them to this post if it helps.

[Marvelman]

Wow! I would've never thought of this. So the casino transferred the funds back to the deposit address of the user? That's funny!
But does that mean that the funds are available to the user in the user account again? Or not... It probably depends on the casino's internal procedures.

On a side note, o_e_l_e_o, you're the true gem in this forum. Big respect!

[o_e_l_e_o]

But does that mean that the funds are available to the user in the user account again? Or not... It probably depends on the casino's internal procedures.

If the casino creates a single deposit address for each customer to use multiple times, then the "withdrawal" they processed to their own address should show up in the customer's account.

If the casino creates a fresh single use address for each deposit, then the "withdrawal" may or may not process, depending on their internal processes as you say.

Either way, it seems that the funds are on an address owned by the casino, and indeed, have already been swept and consolidated back in to their main wallet, so the casino should be able to refund to the correct address.

On a side note, o_e_l_e_o, you're the true gem in this forum. Big respect!

Many thanks. Anything to help the adoption of bitcoin!

So far so good. Everything is fine till here. Even tho winning in a casino is rather unrealistic 

The casino says they sent approx $360 to the player on Oct-29th using the exact same address: 1AWFZhxpQGMmSv9KQjRHi1j4bdhPkhh5Qs

Well, sending using the same address is possible. But in this case this address would be the sender, not the receiver.

According to this post (https://www.casinomeister.com/forums/threads/thebreeze1355-vs-rich-palms-casino.93277/post-1170362) she then told them that "that must be the right [address] if that's what they had".

In this case the casino should have seen this transaction as a deposit and the funds should be available in the players account.
The fact that this is not the case might indicate some really bad software.

But at least the root cause seems to be found, even tho this could have happened a few days ago already if we were given all necessary information.

[o_e_l_e_o]

Well, sending using the same address is possible. But in this case this address would be the sender, not the receiver.

Yeah, the only transactions sent from that address are two consolidation transactions, each with hundreds of inputs, one for 1.3 BTC and the other for 3.2 BTC, obviously neither of which fit the story we have.

In this case the casino should have seen this transaction as a deposit and the funds should be available in the players account.
The fact that this is not the case might indicate some really bad software.

Yeah, it's a bit strange, but given the fact that it seems the casino sent funds to their own address and then swept them back again without even realizing it, then it is at least believable that they don't really understand bitcoin and that their back end is awful.

OP, I would be grateful if you could update us as the situation develops. I'd like to know if my assessment was correct and if the user managed to obtain their funds.

[KasinoKing]

LOL  
I win from casinos a lot - not all the time, but a lot.
When I first started playing online in 2001, I made profit from casinos for 9 years in a row, by taking advantage of their generous bonuses... and that is why I started calling myself Kasino King!
After that I just played for fun - though winning is a lot more fun than losing...

You can see all my stats from those days and loads of pictures on my big wins on my websites or YouTube channel. I won't put a link here in case that's not allowed.

They sent using the same address?
Well, sending using the same address is possible. But in this case this address would be the sender, not the receiver.

And this is why, despite all the great answers from you wonderful people, that I am STILL so terribly confused.

Some are saying you CAN send back to the same address, and some say you CAN'T.
I don't get it.

So your saying that the casino could send it using the same address used to deposit, but in that case, how does the system know WHERE the Bitcoin is going?
Surely to HAVE to have a different "send to" address which is linked to the players wallet

Mark.

[KasinoKing]

Will do!

Currently this is not resolved, but I am still talking to the player and the casino.
And currently I am still confused about how Bitcoin transactions work.
Also I am currently asking myself why I have spent so much time on this when I don't even know the player and they didn't even go though my website to sign-up at the casino...!

But 'tis the season of good will I suppose!

Thanks again for your help,
Mark.

Think of an analogy about real world, physical addresses.

The customer lives at 123 Customer Lane. They send a some cash in the post from their house at 123 Customer Lane to the casino's local branch at 555 Branch Street. The casino can see from the letter the customer included that the money has been sent from 123 Customer Lane. The customer makes a few bets, and they win big. They ask for a withdrawal. However, withdrawals aren't processed by the local branches - they are processed by headquarters, at 1600 Headquarter Avenue. So the casino sends the cash from 1600 Headquarter Avenue, but instead of sending it to the customer's house at 123 Customer Lane like they should have done, they (I think) accidentally send it back to the local branch at 555 Branch Street.

Bit of a newbie question - but I hope there's some experts here who can answer!

Someone contacted me with a problem:
They sent a small amount of Bitcoin to an online casino using a standard address. e.g. 1AWFZsieMdJH8HJeT956HdhsPjhsf3S
Having won and cashed out, the casino says they sent the winnings back to the player USING THAT SAME ADDRESS.

Is that even possible?

Thanks in advance,
Mark.

I believe that using the same wallet is possible, but in your case it looks somewhat suspicious. Usually, if you take part in one or another crypto platform and want to receive a payment, then you yourself need to specify the wallet to which you want to receive your BTC. However, there are cases when the payment can be received only to the wallet from which you made the payment. If you received a payment in BTC, then this is exactly the case, if not, then you were simply deceived. But no matter how it was, the same wallet can be used to receive BTC.

Happy to report that FINALLY the player advised me they got their cash-out this-morning 

After 3 weeks, dozens of messages and numerous hours on Skype with 2 different casino reps, I finally got them to admit that they had made a mistake by trying to send the funds back to the player on her deposit reference.
They sent the Btc on a new reference that the player gave them.

I'd like to thank everyone who replied in this thread, for your help & support 

Cheers,
Mark.

[bob123]

~snip~

Glad to hear it finally got sorted out.

It has been a really embarrassing mistake from the casino tho. I hope they learned from that.
Something like this shouldn't happen at all.

Anyways, your friend finally got his BTC. And they are worth more than 3 weeks ago 

[ololajulo]

All the story behind the transaction looks suspicious to me, I cant rule out possibility of trying to scam you, they could be trying to lure you into it. I guess they are trying to introduce you to the gamble site but were surprised you got so much information to address the process of transaction. After 3 weeks the transaction rectify by who? we dont usually delayed such transaction again so be careful out there. I wish you provide the name of the casino
