He posted on facebook bitcoin mining, $10 to get $100 within 24 hours mining, etc. I tried with my $10 worth of bitcoin transferred to his wallet 1MMnxA9Afb4vdGdVQfBFLXJZSyUGp8HPxb which he claimed to be the antminer node address for investors. After 24 hours, he told me that my $10 has generated $103 and that due to system upgrade my $103 has triple to $300 which will be paid into my bitcoin wallet address if I mine again with $25 within 12 hours and I did so but 12 hours passed, 24 hours and two days now he has not paid the $300 into my bitcoin wallet aa promised. He has not replied my email to him and he has blocked me from reaching him on the messenger app. This guy is a fraudster and I want his bitcoin wallet address block.
