The number of bitcoin ever to be mined may be capped at 21 million but the total supply will always be less. How much less is a critical valuation metric for bitcoin economists. There are a variety of ways and reasons bitcoin can be taken out of circulation. The purpose of this post is to examine one reason: “burn addresses”.Continue reading ~2 BTC Burned in 2018
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.
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.Continue reading Bitcoin Bomb Ransom Fizzled Out: No Payments Made By Deadline
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:
It’s a significant first. For responsible crypto exchanges and bitcoin ATMs operating in this wild west legal environment there are very few FREE KYC/CTF/AML compliance tools available. BitcoinWhosWho.com provides open-source data necessary to adhere to burgeoning global KYC/CTF/AML procedures involving bitcoin transactions.

There is strong evidence to support either thesis. Bitcoin Pizza Day is May 22. No better time to review the evidence. Whose pizza is worth $98 million today?
Eight years ago “Jercos” sold “Laszlo” 2 pizzas for 10,000 BTC. It was the first transaction in bitcoin history for an economic good or service. At the time 1 BTC was $USD00.08.

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

Phished the mnemonic seed and stole many people’s coins. The site was linked from official bitcoin gold website.
BitcoinWhosWho.com started receiving reports of a mass email attempting to blackmail recipients out of bitcoin about a month ago. The hilariously worded text always closes with “sorry for misprints, I am foreign”. Rudimentary block exploring shows at least some of these scam addresses are being consolidated on the Russian wallet service Matbea.com. Continue reading Blackmail Scam Run on Russian Wallet Matbea
It was supposed to be impossible to discover a bitcoin’s private key without the owners’ consent, but the Large Bitcoin Collider “LBC” pool is proving that assumption incorrect. LBC found a 14th private key a few days ago according to their website, the first since April.
A look at the blockchain shows the address, 15K1YKJMiJ4fpesTVUcByoz334rHmknxmT, was quickly emptied to 1GaZi2TSYLns8A85yAQr1Js7Rqjrn5HGZ where the BTC still resides.
