Hello i was looking for a btc forum to post this and get help if possible. i normally use paypal for online payments, i dont deal in crypto, just started accepting crypto recently. i used my local country wallet called unocoin also exodus before, both i had no problem. today i created blockchain wallet because i heard blockchain to blockchain transaction is instant, like i heard i got the btc instant. i will explain everything in steps below.

i advertised selling something(digital good) in a market forum. to contact i posted my discord id. few hrs after a person contacted me, we negotiated price and i said i will have to wait for atleast 1 conformation before giving the goods. he suggested to use blockchain wallet which is instant transfer to wallet within block chain network. so i created wallet on blockchain.com. to test the wallet i asked him to send only little,

-he sent 50$ btc, i received the 50$ worth btc almost instant. the transaction was successful and registered in transaction history
- i decided to test if i can send this btc to my local wallet unocoin. i sent the 50$ worth btc which they took some fee. i checked transaction history, it said 0/3 confirmation, it was pending(which i never received yet to my unocoin after 12hr)
-after the 50$ btc , my buyer sent few 100$ and some 200$ worth total around 900$ worth btc. all this was registered in transaction list.
-after this i created their exchange account on exchange.blockchain.com and i had to link my wallet with exchange acc.
-after linking i came back to wallet and refreshed the page, the balance went to 0. i looked transaction history, history is wiped, and says this btc address is unused.
-i thought maybe its a bug, i refreshed the page, relogged, but no nothing is in account. even checked exchange account, its not there too.
-so i opened 2 support ticket on their site, for both i received confirmation with ticket number to my mail. i did not give this mail id to anyone else.
- 10min after i sent 1st support ticket i received response to junk folder in my mail from totally different domain. i was thinking how did someone got my email id, i only gave it to blockchain while creating account.

This is the email i got from support@blockchainexchange.vip (i knew its scam, so i did not respond this this mail)


-so my instant question was how did they get my support ticket which i sent on blockchain.com.
- so blockchain is compromised or officially scamming, they took the btc back, for what i know it is not possible to charge back btc by sender. my transaction history is wiped, so this is inside scam on blockchain. i did not even receive the 1st 50$ btc i transfered to test from blockchain to other wallet for 12hr, that transaction history also wiped. i can make that 900$ in few days but i want others to know this aswell.

no i googled blockchain and clicked top result(not ads). the address is https://blockchain.com for wallet, https://exchange.blockchain.com for exchange.

If its full of bugs, did they ever refunded btc before?

If blockchain suspected this double spend attack they should atleast give the btc to person who lost in this scam. but they still have this feature after knowing its vulnerability and doing nothing to person who lost means they should be leagally taken down from which ever country they originated from.

They won't give you that amount.

Wallet providers aren't responsible for any amount that was scammed to their users. If the negligence is on their part, they might give a refund but in your case, you were tricked. Sorry with that.

The link on blockchain.com shows an Android wallet. If an address was generated on this wallet, how can that address say "This BTC address is unused". If the balance shows up on the "blockchain" wallet for an unconfirmed transaction, that means they should be acting as the escrow or arbitrator for such a transaction. Judging from the fact that the OPs incoming transactions never got confirmed, Blockchain.com effectively "ALLOWS" such a double-spend attack.

If the confirmation count is still zero, hopefully, OP wouldn't have parted with whatever digital good he was giving the other person. He never intended to send the money and expected that a ticket will be raised. Then sent a email to fool you into sharing your wallet mnemonic. Social engineering hack at the most.

Also, can anyone explain how does a transaction that shows up in the blockchain.com wallet (or explorer) can end up being "wiped" clean?? Is this about non-confirmed transaction being reversed if the attacker used a RBF option at the time of creating the transaction??

You used Unocoin, Is this India? Relying on instant settlements in bitcoin or any other PoW cryptocurrency is fraught with risk. So always wait for that 1 confirmation. Blockchain.com doesn't claim to provide instant settlement so accepting an incoming wallet balance with zero confirmation is a decision that the user has to make. They probably just give you the option to "see" an incoming transaction in the mempool without going to the block explorer.

 

so from this what is see is crypto is not really "secure" coin. someone new always going to fall for such scam. Its really not for normal people and business, its the currency for scammers and businesses who do illegal trades and wants to hide transactions from authorities. only reason i wanted to try this because it dont have big transaction fee, currency conversion fee like paypal. atleast in paypal we can win charge backs. im just going to sweep this under rug as unexpected monthly loss and going back to traditional secure currency. im actually glad it learned this early at 900$ not at 900k$.  Thank you to everyone who took time to explain things.

Why didn't you do this?

Are you trying to say scammers were not there before the birth of cryptocurrencies?
Can you even be able to count how many times have terrorists, drug dealers, warlords and corrupt Government officials have used the US Dollar and other fiat currencies to commit crimes?
Your perception of cryptocurrencies is totally wrong. Even the same PayPal you keep praising has been used by scammers countless times to scam people

We are talking about personal money not the tax money here. how much money from your pocket did u loose to those crimes? its either tax or money these illegal parties make themself illegally. are u saying crypto is not used for such crimes u listed? from my view apart from some individul investor, it is mainly used for illegal transactions to hide from laws.
im not praising paypal, im saying chargebacks can be reverted by filing a complaint.
i looked around and read some blogs about crypto, the 1st point everyone says is they dont trust their central bank.
where can central bank run with whole countries wealth?, out of this planet? is there a real reasons to not trust central bank or they dont trust because everyone says they dont trust? just like news channels play mindgames on election time. again im not supporting anyone, its a genuine question i want to know why everyone dont trust their central bank.

Crypto is a risk and you need to be really careful not to lose your funds. In addition, scammers are very eager to get your funds and are looking for new ways to do so.
