The First #Bitcoin Transaction; Was it for two @dominos or @PapaJohns #pizza?

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

Are Your Bitcoins Safe? Large Bitcoin Collider Finds Another Private Key

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.

The Austin Cain Facebook Scam

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.
