Do you know something about the exchange https://coinspin.net/ I received a transfer to my account on this exchange. Then a message popped up saying that I had to pay 0.02 btc to withdraw funds. I paid the amount. Then I was asked for another 0.05 btc payment which is supposed to unlock the withdrawal limit for this month. A red lamp lit. Which is very interesting. Nowhere in the Internet there is not a single information about such an exchange. I am asking for help in the investigation. there is no address, and only bots write in chat. Sophisticated scam. Watch out for this exchange. If you find out more than I do - write here.
