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.
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.

There will eventually be 21 million bitcoins mined however that will never be the true number in circulation. The distinction is important if you want to precisely measure bitcoin value and market capitalization which is setting new records. Not all bitcoin addresses can be spent. The genesis block can never be spent. Likewise any bitcoin sent to a “burn” address are also forever unspendable. A bitcoin burn address is like an impossible vanity address. There is no private key to a burn address and one would be impossible to generate. These are not merely ‘zombies‘ but truly gone forever. How many bitcoins have been “burned” exactly?
