Really it feels like a gold old scheme to scam people with that trick of depositing bitcoins, it is decryptor ransomware but his site isn't secured in the first place even by that it really looks suspicious at all. People who really fond of scamming innocent people will not really pick any occasion even the whole world is in turmoil because of this pandemic "COVID-19".

Good job OP for the dissemination in this board for people to be aware.
