Bitcoin Bomb Ransom Fizzled Out: No Payments Made By Deadline

There will be winners and losers in the race to become the best bitcoin extortionist emailer. The latest bitcoin scam email campaign looks like it will be one of the losers.

New Bitcoin Bomb Ransom Email A Fake

Starting this morning, from U.S. sources, BitcoinWhosWho.com began receiving reports of a fake bomb threat demanding $20k in bitcoin or a “mercenary” would blow up their building. So far no one has paid any of the 15 bitcoin addresses that have been identified. But, it would only take a few people falling for this to make it worthwhile for the scammer.

The email typically states the bomb or explosive device is made of “lead azide”, “Tetryl” or “Hexogen” but also “tronitrotoluene” has been reported.

Notably, the author really wants to be clear that everything is proceeding “according to my guide”. Oh, and BTW, the bomb will go off by the end of the day if you don’t pay.

The Future of Bitcoin KYC

Free Bitcoin KYC
The addition of two Iranian SamSam ransomware bitcoin addresses to the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) list ushered in a new era in Know Your Customer, Counter Terrorist Financing and Anti-Money Laundering (KYC/CTF/AML) regulation compliance for bitcoin transactions. From now on, no one is allowed to transact with these two bitcoin addresses:

Are these the real bitcoin pizzas?

8.97 Bitcoins Burned In 2017

2,759 BTC Burned All-Time
The total amount of bitcoin in circulation decreased by almost 9 in 2017 due to “burn” addresses. Burn addresses, like the Genesis Block, are deadlier than “zombie” addresses, because there is no chance of coming back once BTC is sent to it. There are almost 400 known bitcoin burn addresses, i.e. valid addresses with no private key, to which, for a variety of reasons, people have sent 2,759.42507135 over the years. In 2017, 9 of these addresses received 8.97140133 BTC. That is way down from 2016 when 26.04 BTC was burned. Continue reading 8.97 Bitcoins Burned In 2017
