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→
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.

We received multiple scam reports of a likely 3000 BTC ponzi exit in South Africa yesterday. Jonathan Weltman, founder of arbX Digital (@arbXdigital), informed his investors he lost all funds via email a few days after the twittersphere erupted with complaints about no redemptions or communications.
We received multiple reports of a bitcoin scam run by “Austin Cain” on Facebook going dark this week. It sounds like a classic ponzi scheme exit.
This is one of the “Invest Coins with Austin” addresses 1FXNLk9BVUt7fCHuu8GQtSCukR4CiyYA6D with total received balance of 39.84 BTC. The Facebook group is no longer accessible. It appears the ponzi is over and Austin is on the run. One of our informants has reported him to the Australian Cybercrime Online Reporting Network (ACORN).
You can run but it’s hard to hide forever on the Bitcoin blockchain Austin.
