Hi,
There's an advance fee scam going on and circulating through various discords regarding receiving "free bitcoin". Users get direct messages on discord to register on a certain website (https://nivbit.com/, https://zelbit.exchange/ and others) and activate a code in order to receive their free BTC. The websites are technologically very well done, while the "operators" and discord spammers are either Russians or from Eastern Asia so their English is pretty bad.
After you register and enter the code you get 0.71 BTC on your account (note that your "account" doesn't have a hash or an address so you can't check your balance on any blockchain explorer). You can exchange the currencies and everything is very well done from website tech perspective, but when you try to withdraw the amount you received you get a message popup that you have to deposit 0.05 BTC ($600) in order to be verified. The website doesn't offer your wallet address (since you don't have one), but rather the scammer's address. Their addresses or wallets are "clean" and without past transactions, so that if you were to check on a blockchain explorer, you'd think it's your wallet on that website, but it isn't and they change deposit addresses regularly.
When you click withdraw and get that message you will receive an email from the scammer that goes like this:
"Please finish your verification. You need to make 0.05 BTC deposit on a special address which I will give you. For more information please email me.
Best Regards
NivBit Team"
They're quick to reply and will pretend it's not a scam even though it obviously is. Some of their operators are from Yekaterinburg area in Russia (websites' servers are located in Moscow) even though they insist that they're called nivBIT Financial Company OÜ based in Estonia disregarding the fact that that company doesn't exist and there are no addresses or locations on any of the websites.
Operator's Email: William Hosten <[email protected] - Russian guy, pretty bad English, from Yekaterinburg area judging by the timestamp on his signature (which is in Cyrillic lmao), he could be the only guy doing this scam though, since the email says "please email me" instead of "us" as it would be if they were a real company.
Some of their wallets used for depositing (you bet those are gonna get changed as soon as they scam someone, or see this)
BTC - 3NB4ZTPuE1zoZSynCbXQFnVedsAS4UowLX
ETH - 0xB0a2059fA82d8507c19cC400Bed5b36EbDD91BF0
LTC - M85yQEr8aTWCJMTscytEFJ7pjk9SDSxpRr
They don't accept any other cryptocurrencies like other altcoins as they're too volatile and could drop in value, even though the buttons exist on the website albeit they're greyed out.
