This is not an instruction for fraudulent schemes! Here are the cases that you buy/sold cryptocurrencies carefully and safely!
Triangle and compromised cards.
You sell bitcoins on localbitcoins or through bots. You receive payment, and you approve the transfer of your cryptocurrency to the buyer's wallet.
There may be two scenarios:
- later a fake man calls and says he transferred you money by mistake and will complain to the police,
- a buyer who was deceived by the same fraudster who was given your number to transfer calls. He's going to complain to the police, too.
In any case, the only expectation is that you will get scared and return the money. From the point of view of the law, you have not violated anything (at least until the law on cryptocurrencies is not passed and you can buy them without any licenses). But the funds found/accidentally received must be returned.
Just in case, save screenshots of correspondence in the chat localbitcoins and do not forget to ask the buyer, from which wallet to wait for payment and do not accept payment from the terminals!
Also, fraudsters can buy BTC from compromised cards and so money money, but your account or bank card in this case is not blocked. However, they may be considered accomplices in rare cases.
On mindfulness
The buyer uses Yandex.Money, zIWI or Webmoney. Sends you his wallet and makes a translation. Only here translates the amount with the protection code (in the case of Yandex.Money) or does not confirm the translation, etc., that is actually your balance is not replenished, and you, looking fluently into the interface and seeing the presence of the transaction, "release" the cryptocurrency.
In fact, the buyer will never send the protection code and will not confirm the payment, so in 24 hours the payment will be returned to the sender, and he will have free bitcoins.
Instruction:
- ask the protection code (of course the scammer won't answer)
- wait until the debate opens. This feature does not appear immediately, but after a certain period of time. The opening of the sport is under the cryptocurrency sending button.
Open the argument. Usually the attacker is not involved in the dispute, and this automatically counts as your victory in it. Dispute resolution, if the buyer does not close the transaction ahead of schedule, takes place within 12 hours.
In general, very often asked to "release" (send) bictoins, without waiting for the enrollment of money: send screenshots, some receipts. They can simply send a text message to the phone under the guise of Sberbank and other services that the money is deposited into the account.
But you should be guided by the iron rule "Morning - money, in the evening - chairs" and check the balance of your account, not just sms and email notifications.
The seller's ejection from the top
From different accounts open deals with sellers from the top for all available volume. Naturally, the money is not transferred, but the seller's BTC is temporarily frozen. So you can go to the top with a less profitable rate, getting rid of competitors.
Exit - use offer settings in the localbitcoins interface, filters limiting access to it for customers: a confirmed phone, the maximum volume of the transaction with the customer (for those who do not already have a single transaction), the level of feedback (note that this the metric does not take into account new users) and others. Don't forget to check customer reviews.
And also don't put the whole "cutlet" for sale, even if you want to sell your entire balance. It is better to divide the coins into several safe parts.
Why are they asked to translate by phone number?
The buyer-fraudster often asks to transfer the phone number to the Sberbank card. This in itself is undesirable, because the personal number is better not to disclose to strangers: it can turn into just unpleasant spam and calls from call centers, and can result in blackmail and so on.
The phone number in such cases is still requested then to illegally restore the SIM card to the left person. And then use all the accounts tied to the phone number. You may ask, how can you restore a card without a passport? It is really possible to do it, although operators are trying to fight it.
Also, knowing the phone number, the attacker can easily intercept the ss7 network to receive text codes of confirmation.
Mistakes with ziwi?
We've found that people who haven't used Kiwi before accept this deal and confuse the wallet number of ziwi (which looks like a phone number) and just a phone number. And instead of transferring to the account, replenish the balance of the phone.
In this case, the seller may not have access to the number (many use separate numbers to work with the cryptocurrency) or simply do not enter the position of buyers and do not withdraw money between accounts.
Then the seller refuses to transfer bitcoins. In this situation, the support takes the side of the seller and recognizes his actions as correct.
Verified seller
A seller with a bunch of positive reviews offers bitcoins at a price below the market price. It so happened that usually the owners of an honest high rating put prices even 20% above the market. And dumping can be a signal.
Reviews are easy to screw up from other accounts because there is enough mail on these exchanges to register. By sacrificing 1% of the transactions to cheat votes, the scammers will cheat on the spending when they do not send you BTC, and the rubles are cashed.
How to detect fake reviews:
look at the spread of purchase selections, maybe it's always only the smallest amounts (of course, often and honest sellers buy a little, but if all the sums are very similar to each other, it is worth thinking),
reviews coincide with the style of writing (it is possible that the scammers do not go so far as to write a variety of reviews, the style can often be the same or even be a copy).
Also in Telegram, Instagram and other social networks there are commercial offers from certified tradesmen, which will help you earn. Common sense says that a successful trader to work with your modest capital is unprofitable. But the fraudster to earn an extra thousand, doing nothing - quite imagine.
Often these accounts also use fake evidence: galleries with reviews and screenshots of translations.
Do not believe such "authorities" and for buying/selling use only sites with customer protection: direct transactions are now very risky. Or deploy a smart contract.
Sometimes the seller is trying to lure from the proven site, agitating against the commission of the service. The attacker can offer an escrow-service, some proven guarantor. But such sites are easy to deploy in an hour.
Earnings on course differences
Such scams have been repeatedly exposed, but people still carry money there.
The scheme described by the author of the commercial proposal is as follows:
- you buy bitcoin on one exchange, which is given by the author with a special reference,
- on another recommended exchanger sell cue, as if with a difference in course,
- get rich.
That's just money from the system can not be withdrawn. This arbitration system is a pure deception, and all sites belong to the same owner. As well as the money given for BTC.
To pump out more money, you use entry thresholds, for example, only from 0.03 bitcoins, talk about the change of the ruble to the dollar and ask for more to make money and so on.
