Did you mean the last transaction which you get 0.00109813 BTC?

Unfortunately we can't forbid anyone who want to sell coins to our address, but we can choose which transaction aka UTXO when we want to transfer our coins, it's called as coin control https://bitcoinelectrum.com/how-to-spend-specific-utxos-in-electrum/

The amount is not that small unlike dust transactions, now it's your choice to send the coins back to the sender address, freeze it or steal it.

Just a quick check if you're in control of the wallet mentioned—you have the private keys and can freely send funds out. Then, someone probably sent it by mistake. They most likely have copy-pasted the wrong address.

But if it's "watch-only" or in some random website, and you can't send the satoshis out, then there is a catch—scam. Best to expound your situation.

Only thing we can go off is the transaction ID - https://blockchair.com/bitcoin/transaction/4b84fdf2ef59ff1544811ecfa39ab3a97d07b01dce3649aa3ae1bd4a81cfd430
This will show the address that sen it, but can no give more info.

Can you identify places you may have posted your address, to help narrow the search.

...now it's your choice to send the coins back to the sender address, freeze it or steal it.

I do not think it is stealing in this context.

It's quite a coincidence that someone sent you some satoshis, even I'm curious now
Have you posted this address anywhere, or have you registered for withdrawals with this address?
Because if this BTC address is yours, and you've never passed it on to anyone, it would be VERY coincidental for someone to make a mistake and send it to you




From what I saw in explorer, an address (source) sent BTC to 1983 Outputs
It's usually an exchange address or someone paying something to several clients and/or users

Could an exchange make such a mistake, though? These processes are automated; there's no way an exchange would make such a mistake. On the other hand, how common is it to randomly receive money in your Bitcoin wallet? The addresses are extremely randomized, and it sounds extremely unlikely. A dust attack also sounds very unlikely, as it's not a few insignificant satoshis. Perhaps the OP had requested a withdrawal from somewhere and completely forgot about it? Perhaps a casino or another similar service was shutting down and was sending any outstanding balances to their wallets?

[btcltcdigger]

It could have been someone sent to the wrong address, or potentially it could have been an old withdrawl that was tuck in the mempool for ages and you simply forgot about it.
You can either keep it, or send it back if you feel morally obligated. Up to you

[JeromeTash]

It doesn't seem like an unsolicitated transaction. If it was a very small amount, we would understand it's some sort of dust attack and the address from which the BTC is sent from usually spams other different addresses too. It appears the transaction was sent out from an exchange's (or another service's hot wallets, such as a casino)

Try to think about any possible past deals you might have made. It could be some payment you have long forgotten about or a tip?

[BenCodie]

If you hadn't forgotten about an incoming payment or a time that you shared your address with a likelihood/certainty of receiving something, or if someone hasn't accidentally inputted your address, this is an extremely rare thing to have happened. The only other thing I can think of here is that it is an (expensive) attempt to identify you? If so, maybe employ some privacy techniques to prevent that, and enjoy the free Bitcoin.

I cannot open this Blockchain link, I would have done a little digging.
Check if you have submitted your bitcoin address to an exchange for a reward.
It could also be that you dropped bitcoin somewhere for donations you didn't think will come.
Trace the last transaction the address did, you could have a clue and also look out at the balance remaining in the address that sent the coin.

[sheenshane]

The amount is not that small unlike dust transactions,

It seems like a dust transaction to me, it has 1,983 addresses that receive different sats, some are dust and some are quite large amounts, which I think is a mistake in sending.
It's almost 1 Bitcoin, which is a huge amount, and that might be a gesture of generosity from whoever did that.

Let's consider that it isn't an unsolicited transaction and could be a reward from an airdrop.
@OP, have you joined any groups or shared your Bitcoin address elsewhere?
I remember when I was also part of a dust transaction before, but nothing else happened.

Keep it, send it back or freeze it first before taking a next action, three options to do.

Value of that transaction is bigger than normal dust transaction.

thank you all for you answers
i don't remember sharing my address with any other person or send/received .
what i remember that i did a swap transaction only .
also is there difference if the the my BTC address is from cold or hot wallet ?

If you ever use your address, there's a chance they can find out your address because Bitcoin use public blockchain.

There's no difference, but it depends on the developer/producer.

Hot wallet could be non custodial wallet that connected with internet or centralized exchange, if it's centralized exchange, there's no privacy. Even cold wallet (assume it hardware wallet) might be not completely safe, just like ledger who suffered data leaks in few years ago.

You have both exhausted any ideas that I can come up with why OP can receive payment for unsolicited transaction, it is either that the transaction was intentional or it was a mistake. We can rule out whether it was a dust attack because the amount is not insignificant and also it is very unlikely that it could be a mistake from an exchange because the process must be automated. My best bet is that OP had shared his address somewhere and totally forgotten about it, it could be a reward or repayment, he has to think deep to remember. If he decides to return the BTC to the sender's address, let him not be in a hurry to do so, he can give a little more time maybe he can remember the source of the payment.

A cold wallet is a wallet that has never been connected to any internet device, that has always been offline
But the public address may have been shared, no problem

A hotwallet is a wallet that has been generated or is on an internet-enabled device, for example if you generated a wallet through Electrum on your PC

In short, it makes no difference whether your wallet is a cold or hot wallet.

After some more thought, I've only come to two conclusions, assuming that the address that sent you the satoshis is either a payment address or an exchange address:

1 - you had money to receive from someone or some exchange and you forgot it
2 - the person who made the payment took your address by mistake from some list

[CryptSafe]

I had to check for myself to see what really transpired, but from the transaction, I am convinced it is not likely a dust attack but rather a bulk transfer of BTC to a different wallet in a different volume. Maybe a payment for something or so, but I am convinced it is a genuine payment, and nobody would have made such a mistake for payment of such an amount. The OP wallet has received payment, and it's not a new wallet to say, and this is likely that OP must have taken part in a contest, or so was possibly submitted his wallet and long forgotten about it.
Looking at the sender's address, it is very much active and has transacted a huge volume of bitcoin, which means the transaction is a real one and not a dust attack. Maybe OP should do his findings by trying to recall, because there is every possibility OP had taken part in an exercise a long time ago, which he has forgotten.

Not that there is necessarily a link between both transactions, but telling us more about this swap transaction and which service you used can help us better understand what happened.

also is there difference if the the my BTC address is from cold or hot wallet ?

No, it doesn’t matter whether you are using a hot or cold wallet. It’s irrelevant in this case as there is no way for the sender to know the type of your wallet.
Unfortunately, there is no way for us to know who the sender is, and all we can do is speculate. If I had to guess, I would say this has something to do with the first transaction you received (but this is just a guess!).

[Cricktor]

Frankly, I wouldn't mind to receive a lot of unsolicited transactions of ~1mBTC like OP.    Who sends such an amount without consent? Strange...

At first when I came across this post I thought it was about something related to dust attack but upon going through the transaction details you provided op I guess I was wrong because it seems like a normal transaction with a decent amount and a couple of consolidations too.

Come on who wouldn't want that, I don't mind 1btc either  however jokes aside, the chances of that happen is almost around 1 in a million there is a high chance a mistaken address receiving the coin hasn't even been created then.
